71e795812f April Tag Release Fixes
Everything works. Running out of memory is fixed and the rotation value
is valid now. For 320x240 operation on the STM32H7 we're going to need
on the order of 1 MB in the entire frame buffer. The code is designed to
handle us getting this amount of memory without any new changes for
320x240 support.

55716a632a AprilTags Main
This file includes all of the relevant header/source files from the
april tag library merged into one big file. Additionally, it also
includes heap/quicksort code. I've done the work of going through
the april tag library line by line and fixing it to use fb_alloc,
floats, and our fast math functions.

Anyway, I'm sending this massive file by itself first since it's so
big. Note that we migh in the future want to pull things out of this
file for our own use later if we need linear algebra support.

02af722fe8 Fixed fb_alloc() with mark for recently re-worked code.
I also tested the firmware for about an hour to make sure there was no
stack leak.

Note that I prefer for fb_free() to still be called versus
fb_free_till_mark() doing that for you in the code.

For functions without this fix they will just free the entire fb_alloc
stack when an exception happens. For functions with this fix they will
only free up to and including the mark. Since there are no places in the
firmware where you could start building a second fb_alloc stack when one
is already in place this point is moot currently. But, if we do
something like that in the future the problem will have already been
solved.

Any new code or re-worked code should use the mark function.

d6b49adefa Speed up lens_corr.
Speed up the algorithm by fixing the abs() issue. Do not use that
function in any of your code. It by itself cut the speed of the code
in half. I don't know what's in that function but I'm guessing it does
ABS of a float using ints or something.

I made the zoom parameter functional now too so you can use lens_corr to
zoom in on the image. Argument parsing is handled too. Finally, I
updated the only script where this is used.

Note that I'm able to get more than 10 FPS at 160x120 on the M4 and 15
FPS at 160x120 on the M7. Previous this was at about 5 FPS and 7.5 FPS
respectively.

0111084125 Updated stats code
We now have a method to get an the normalized histogram of an image
patch. The histogram is returned as an object with methods too. You can
then get the stats off of the histogram or just get the CDF of it. The
CDF is particularly useful for automatically chaning the the color
tracking bounds.

* This function filters keypoints far from the centroid, it's very useful for finding an accurate bounding box for an object.
  If a bounding box for the object is not needed, the centroid can be used instead since it's not affected too much by outliers.
* The filter finds the centroid of all the previously cross-matched keypoints then finds the mean, variance and standard deviation,
  it then filters keypoints with a distance higher than standard deviation from the centroid.

af15ec6eb3 New Blob Code
The new API is backwards compatible with the previous one except for
advanced features. The new blob code uses a flood fill algorithm that is
3x faster in filling out blobs that the previous code. On the M7 the
performance cap of 30 FPS is usually reached.

Additionally, blobs are objects with named attributes now so you don't
have to index access them anymore. However, index access is still
supported.

7af818c4d8 Finished up optical flow code.
* Added pooling functions to make getting small images easy. set_binning
works too... but, it zooms in way to much. pooling functions aout you to
shrink the image while not zooming in.

* To make the pooling functions easy to use I created a version that
pools the image out of place and one that pools the image in place. The
inplace pooling function can work on the frame buffer (see edits to
sensor.c)

* I added the code to do hann windowing to the FFT lib. However, I
commented it out after it improved performance by basically zero.
Specialized windowing stuff will only come in handy for folks trying to
tune their algorithm... not in general for everything.

* I added subpixel resolution for the phase correlation code. You can
now track the image movement really precisely. Additionally, I fixed up
the displacement outputs to give expected results. I also added a QoR
output for the displacement code so that you can know when the results
are bad.

* Finally, an example script has been added to show off the features.

15aed91efd Fixed FFT and Phase Correlation!
There were some mistakes, they are fixed now. FFT 1D and 2D work
flawlessly. No problems with that code anymore.

As for phase correlation I need to study how to interpret the output
better. The function generates noisy results once you move the image too
far and I'm not quite sure if I have the code right for detecting
positive and negative displacements.

45fdcc973e Add FFT Code and Phase Correlation Code
The heart of the 1D FFT works. I tested this on the PC. However, 2D FFTs
may have issues and the phase correlation algorithm does not generate
the expected results. That said, most of the work is done. Stuff just
needs to be deubgged.

The FFT lib is designed to handle up to 1024 point real FFTs and 512
complex FFTs. As for 2D FFTs, we can do up to 64x64 pixels. After which,
we don't have enough RAM to handle them because they use up about 128KB
each.

Things to do... the 2D FFT needs to be verified. So, we need to run an
image through it and then back again to verify that there are no
problems. Then we need to compare the 2D FFT output with another 2D FFT
algorithm on the PC...

Once the FFTs are known to be good we then need to make sure the phase
corelation algorithm outs the correct results. We need to test that with
multiple shifted images, etc.

Added the ability to turn AGC off. Kinda will need the ability to restore

Added the ability to turn AEC off. Objectively this function probably
won't be used. But, in low light situations it can help.

Added get_fb() to allow you to get the last image snapshot returned.

There was some old exposure function in the code that was getting
optimized out. So, I deleted the used methods that didn't have any code
in them and commented out the only method that did.

7a01a9bede Final Imlib Cleanup
Finished going through imlib.c.
-> Histeq uses fb_alloc now and has hook for RGB histeq when reserve YUV
LUT is added (coming soon in next PR).

Cleanuped py_helper.c/h
-> No functional changes. Just added some header info.

Finished going through py_image.c
* 1 - Finished general code cleanup and updating everything to using new
library functions. In particular, I updated the remaining find_*
functions with the new roi clipping code when they accept rois.
* 2 - Made blob stuff return a list when nothing is found so you don't
have to do an if on the returned value anymore.
* 3 - img subscr is more powerful now allowing image reading and
writing. I updated this because I had to use it to find a previous bug
with socket.send() for the WINC driver.
* 4 - Renamed find_eyes to find_eye. Because it just finds one eye.
* 5 - Other than that just general code cleanup to make functions look
consistent.

And yes, changes have been test. Face tracking, eye tracking, keypoints,
etc. all work still.

Future things todo before release:
1 - Change all LAB stuff to YUV.
2 - Add in reverse YUV->RGB LUT and update functions like Mode() to use
this so they don't generate messed up outputs, also histeq() too.
3 - Add any remaining sensor control functions like agc control.

367e5fdd3d Improved JPEG capabilities.
* Added the ability to control the quality on JPEG functions... However,
due to our JPEG implementation this doesn't seem to help. 90% JPEG
quality images and regular images should be about equal. But, you can
see heavy degredation with 90% still. E.g. text is unreabable. Not
exactly sure why this is happening but it can be fixed later.

* Changed the compress() function to compressed(). Also, it now
compresses using FB_Alloc to prevent realloc issues when compressing.

* Added new compress() function. This function compresses an image in
place and if that image is the frame bufffer then it will update the
frame buffer bpp value to reflect the image was compressed. Users can use
this function to basically finalize the frame buffer and then pass the FB
to functions that need to send image bytes. The benefit of using this
function is that it should allow higher quality JPEGs and let everything
run at a faster speed while connected to the IDE.

I made this function to speed up WiFi. However, I encountered a bug with
the winc.send() method. It appears to zero the bytes it sends. I didn't
debug further except to verify that the image data became zero after
calling send.

b534dc6ffc Imlib cleanup
*Changed subimg to copy.
*Made blend work the same way as all our other double image argument
functions.
*Changed bilt to replace (the name of bilt is way to esoteric). Replace
gives you the basic assignment op.
* Removed scale/sacled. I removed this code because we don't want to
encourage people to scale things and allocate additional images in
memory. I decided to keep copy() for completeness sakes... but, I don't
see anyone using it. (By completeness sakes I mean that we now have the
assignment op, copy op, etc. for an image object).
* Removed rainbow. This feature is built into the FIR module now.

Moving on, compress needs to be renamed to compressed and a new compress
function will need to be added.

The compress() function will compress the image (or frame buffer, etc)
and not return a new object. The compressed() function will return a new
object and not compress the original image.

The compress function will make it easier for users to compress images
once they are done working on them before sending the image some where.
I don't see compressed() being used much then after adding the
compress() function. Since the compress() function won't use up heap
space this makes it very good.

d1ff36602a New blob code.
Blob tracking has now been updated to work without requiring prior
segmentation of the image. You can still run it on a segmented image,
but, that is not needed anymore.

Use the copy color feature of the OpenMV IDE to get a color in the
image. Once you have that you can then pass the color to find_blobs which
will output a tuple of lists of blobs for each color. By default, all
blobs less than 1/1000th of the image are filtered out, however, you can
add a custom filter function which gets the image and the blob about to
be added to the list and you can decide to filter it or not.

For marker tracking, we now have a function called find markers which
basically merges all the blobs found by find blobs into one list of
blobs. Each new blob will have a color code value which will tell you
what colors are part of that blob. We support tracking up to 30 unique
colors this way.

401b7b72a8 Added mean, median, and mode filters.
Mean filter -> Fast and easy to use. This will likely be the only filter
that gets alot of action on the M4.

Median filter -> Works really well, but, slow. On grayscale at 160x120
you can get also 10 FPS with it for a 3x3 kernel. That said, it's still
slow. Also, the code only works for 3x3 and 5x5 kernels.

About the previous histogram filter... technically, that filter should be
better. However, it suffers from a startup cost. The operation of finding
the median point in the histogram costs too much to compute. This is
what causes it to be slow. On very large kernels it will be faster than
the sorting median alrogithm I put up... but, large kernels will be too
slow for anyone to use anyway. The paper Ibrahim linked to about it
showed it being used for like 7x7 kernels and up... so, I think the
researcher who thought of the idea was really thinking about the
algorithm for large kernels.

Mode filter -> Works great on grayscale. Not so much on color. I think it
needs to be run on the LAB color space instead of the RGB color space. I
say this because it causes pretty strong artifacts around edges. When we
get more flash we'll be able to have a reverse lookup table for LAB to
make the mode filter better. Until then...

88907c438c Redid MLX Code
First, a few things:

The MLX 16x4 sensor has just too low of a resolution for mass appeal for
the price. The product is not going to sell very well. We need to look
into supporting sensors with a better res. Like the FLIR 1. The MLX
module was renamed to the "flir" module with this idea in mind.

The flir code now takes care of doing scaling and blending itself. I did
this to get rid of the user having to scale the image themselves and
blend themselves. Its too easy to run out of memory given our current
ultra small heap. In general, anything that requires multiple images in
RAM has got to go. When we do another OpenMV Cam with external RAM in
the MB range then maybe such functions will be safe. But, right now they
are definately not.

Anyway, moving on, I fixed a few bugs with the MLX math code. But, for
the most part was correct. I also added reconmended polling code for
brownouts as required by the datasheet.

Last, I designed this code like the LCD code to support a type value
when inited. This will allow the system to user a different sensor in the
future without any API changes to the user.

I will add test scripts for this next. Basic usage follows:

import flir
flir.init()
flir.display_ir(sensor.snapshot())

And that's it. Super easy. If the user wants the raw temp values they
can use flir.read_ir() to get the ta and to values. The display function
has a hidden alpha and scale argument for controling blending and the
min/max scaling.

The previous way we worked out scaling kinda sucked... it was a good
shot, but, controllable min and maxes that autoscale by default just
work better. If the user knows the temp range then they can just set the
min and max.'

Anyway, longest commit ever done.

File reading is runing ultra fast now. We're getting that SD card speed
the STM32 promised now. The file buffer commands have been updated to
alloc as much available memory to read as much of a file in as possible
now to speed up things. This works really great.

Note however, while the file buffer is active you have to use the file
buffer versions of tell and size. Spent a few hours on tracking down an
error related to not using the buffered versions.

14dbcbd73c Updated code to use fb_alloc.
All file write functions now use fb_alloc to go much faster. Writes are
re-directed to the extra frame buffer RAM and are grouped until they can
be written in a massive multi-block write to the SD card. We get the
best SD card write speed by doing things this way.

Ideally we'd want to buffer the whole file... but, this is about as good
as we're going to get for now.

Going to fix reading functions to use the same buffer next.

98f4dde21f Add new morph function.
The morph function lets you convolve the image with a kernel. It's
decently fast right now. But, in the future we'll have to optimize it by
a lot (unrolling loops, using SIMD instructions, etc.).

Anyway, along with morph I added an edge detection test script showing
how you can use a high pass filter on an image to get all the edges in
it. This is not as good as canny edge dection... but, it's about the
same and fast enough.

We'll need a Hough Transform system in the future to make edge dection
useful. Not sure how that will be implemented... so, that's going to be
far away for now.

fb8b357c24 Dilate and errode working.
The old code did not actually implement the errode anhd dilate kernels
correctly. However, it migh have been a little faster because it avoided
the boundary problem.

In the future we can optimize all the kernel code to have different loops
for doing the edges of image versus the center. But, for now, this is
good enough. QVGA color tracking with kernels will be slow, but, the
speed can be improved with QQVGA resolution. Using a 3x3 kernel is
plenty fast. Larger ones are slower.

I also added the ability for you to set the threshold for erode and
dialte. This lets you make the kenrel a little bit smarter so that it
won't errode or dilate a pixel unless the threshold is met. Meaning,
you'll be able to use erode to erode an image down to 1 pixel wide
lines.

It now figures out the file type from the file extension. If no file
extension is given it just saves the file as BMP if its not a JPEG image
or JPEG if it's a JPEG image. If you specify an extension and the file is
not of that type then it will give you an error.

The new test_save.py should run until you reach the JPEG image part
where it quits due to lack of JPEG support natively on OV7725 boards.

think only grayscale is going to be fast. All other formats require a

The negate function gives you the ability to negate an image before

I believe it would have been optimal to work on the RGB565 image in the
LAB color space. However, since we don't have an inverse LAB lut this is
not possible. If we could replace LAB with YUV then that would free up
space to have an inverse YUV table (YUV->RGB).

Kwabena W. Agyeman
024b16d475 Added some helper stuff.
The alloc functions allow you to use the framebuffer as a storage space.
It's very simple but effective. You can alloc which puts some memory on a
stack... and then when you're done you can free which pops the stack.
Pops (frees) must be done in reverse order of pushes (allocs).

In general, functions should call the init code before using the stack.
It could be in a bad state.

Also, I added some wrappers for file system functions to make that stuff
easier. This will be used in the future.

Additionally, I added a function to get the intersecting rectangle of an
image. This will be used for all functions that accept a subimg
argument. This function allows the user to basically pass any wild and
crazy rect they want and the function will find the intersecting area (if
it exists) and return just that to operate on. This is good for "do what
I mean" functionality versus "do what I say".

Fixed up array functions.

84a964f930 Fixed up array functions.
There were a lot of missing features in the array module. I added
quicksort based on the MP sort function and I expanded the array code so
you can do stuff like take() which lets you get an object from an array
and easily put it into another array.

I also fixed the "struct array" problems in the code. Anonymous structs
have to go.

c622e05b58 Re-added timeout.
Given how the SCCB won't fail it should really be 0... but, then the
rountines wouldn't return if there was a failure.

b6eb26d324 Lowered timeout.
It was previous set to 10 seconds... since the timeout is in ms. Now
it's at 1 second. This represents 100 clocks at 100KHz I2c. Also, I
noticed general call mode was being set for the I2C which is not at all
something we want (the ability to address multiple devices at once).

I tested the changes with all my cameras. No problems. This was 4 units
(2 being the original protos).

Kwabena W. Agyeman
456c4ab757 Made XALLOC better. Now the functions detect if you are trying to alloc
0 bytes and don't fail if you do that. Additionally, I added some
comments on behavior. (I studied what the gc functions did extensively
to know the behavior of this stuff). All changes have been tested with
code that does memory allocs.
