9eba59c6c1 Update to full invariant image.
This commit updates the shadow free invariant image to 2 colors from
just grayscale.

If we need to save ROM room in the future we'll just disable the LUT and
have the algorithm run with the regular C code. Right now this is not an
issue.

7516d7699f Add Advanced Optical Flow scripts
Someone asked me about doing a field of receptors before. These scripts
show how to do that. Also, added example scripts for calling the linear
polar and log polar methods added previously which power
find_rotscale().

213396d090 Complete Overhaul of phasecorrelation
Just doing one big commit/PR here since I noticed that breaking it up
causes issues.

Anyway, these fixes give us GOOD/WORKING/FAST optical flow now on the
OpenMV Cam M7. A number of changes were made to the optical flow
scripts. You have have absolute and differential estimation example
scripts. Additionally, you also have the ability to measure rotation and
scale changes too. Linear/Log Polar conversion was added for this. Users
may use the new code for generic image manipulation too. Finally, I
updated the power of 2 resolutions since you actually HAVE to use them
with optical flow for the phasecorrelation code to work correctly.

I have some more advanced scripts coming after this. But, This commit is
already getting kinda large so I'm stopping it here.

7be0a7a182 Add exposure control for all sensors (#292)
* Textual register cleanup.

No functional changes.

* Add exposure control support.

You can now set the exposure for the camera in microseconds (versus an
opaque unknown value previously). First, we have a new method called
get_exposure_us() which will get the expsoure time in microseconds. This
let's you determine what the auto exposure algorithm set the exposure
time to. Second, the previously implmented set_auto_exposure() method
which allows you to turn aec off and on accepts a exposure_us keyword
argument when you turn aec off to manually control the exposure.

The next commit will add support for other sensor types.

* Cleanup register formatting.

No functional changes.

* Add exposure control support for the OV2640.

Register access for this chip is a PITA.

* Formatting Cleanup.

No functional changes.

* Add exposure control for ov9650.

Just doing it for all sensors.

* Add missing 2 factor.

* Added exposure control for the MT9V034.

* Add exposure control example.

Works well on the OV7725.

046a2e1825 Restore MAIN_FB() size on snapshot()
This fix allows "copy_to_fb" with a different resolution than the
current frame buffer to work. It also allows the frame buffer to be
resized, etc. In particular, the pooling methods I added for optical
flow work again... you'll also be able to scale the frame buffer too.

Add extra frame buffer.

27f5110ab7 Add extra frame buffer.
You can now allocate an extra frame buffer for storing images. However,
this takes memory from the main frame buffer. In particular this reduces
the RAM for many methods that do image processing making memory errors
more likely to happen. Note that you may allocate as many extra fb's as
you like. Dealloc happens in reverse order.

Anyway, you can use this method to now storage things like difference
images in RAM allowing for MUCH faster frame difference image
processing.

Moving on, to keep memory management sane... the second fb looks just
like an image and you can use all the image methods to load and update
it, etc. That said, if users deallocate the second FB they need to *NOT*
use the image pointer anymore. There's no way for me to delete the image
pointer in python right now so this is just something that has to be
manually managed (even if I did setup a deconstructor the second FB is
on a stack... so, things wouldn't work so easily with that).

It's now faster to be more useful.

Need to work on HDR for the sensor and making the sensor output better.
I fixed some issues with the illuminvar() method going crazy when it
gets colors with values near 0... but, the shot noise from the sensor
adds a lot of noise to everything. Fixing this will likely solve a lot
of algorithm problems.

937aa1fa22 Add chrominace and illuminace invariant image generators.
Both algorithms were tested on the OpenMV Cam using images loaded from a
file and work correctly. However, shot noise from the sensor.snapshot()
makes the output value somewhat worthless except in a situation unless
you've controlled for it. Anyway, the illuminvar work best when the
image is constrained to a very particular view point looking at a flat
scene without shadow and then a shadow enters.

(Not adding demo's for these methods since the output looks like crap
unless you've put some work into constraining the scene... need to add
HDR code and other stuff to the sensor module to get better images).

For easy line following mainly. In non-robust mode the line is computed
using least squares. In robust mode the line is computed using the

Medians operation because it costs more CPU time... but, more
importantly there's no way to improve the centroid estimate so even if
the slope is more robust the line will be drawn in the wrong place.

dc6ab59cfd Add Image Writer/Reader
These two new classes allow you to record image data for later viewing
at the same speed the image data was recorded. Unlike GIF/MJPEG the
image data is stored on the file system completely uncompressed in
native frame buffer format making super fast reading and writing
possible. Recording VGA Grayscale at ~13 FPS is possible along with
playing it back. (That's about 30 Mb/s folks).

...

The motivation for writing these scripts is so that you can record video
of something like a line following track, take that video home, and work
on computer vision algorithms for that data.

These classes should make it a lot easier to use the camera at home now.

Moved structs along with image copying code from sensor into
framebuffer.c so that we can use the new copy_fb_to_jpeg_fb() function

Also, I noticed that the MAIN_FB_SIZE() value is not calculated
correctly in all cases. Will fix later. Trying to keep this commit clean
for just the refactoring.

Todo - skip frames does not run long enough anymore for auto white

55e4809ff6 Image Streaming Code
The user can now call compressed_for_ide() and compress_for_ide() on an
image to make a jpeg compressed image formatted for transmission over a
data link other than USB. Note that OpenMV IDE will automatically handle
one of these compressed images ending up in the frame buffer and display
it like normal.

To send the image data the user can do:

print(img.compress_for_ide(), end='')
print(img.compressed_for_ide(), end='')
uart.write(img.compress_for_ide())
uart.write(img.compressed_for_ide())

and etc. As mentioned above, compress() compresses the image in place.
And that in place compressed image will then end up in the jpeg buffer.
OpenMV IDE will automatically handling decoding these special compressed
images when this happens.

All variations of the above code have been tested and are working.

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.

The automatic grayscale and rgb565 color tracking scripts are very cool.
