On this tip I always found opencv to work way way faster just dropping the color depth of whatever image as such

#12Did you see the "By The Power of Grayscale" submission and go digging?
Yes, that's exactly how I discovered it :-)

#13Since this is intended for embedded systems, supporting ARM DSP extensions would be beneficial. Correct me if I'm wrong, but I have not seen any compiler generate those instructions, other than through the use of intrinsics.
I would add the support if I needed the library, but I don't, at least not yet.

#14I basically did the same thing a few weeks ago! =) => https://flatcv.ad-si.com It will be interesting to see what you did differently!
Nice. Any plans to add support for affine transformations and perspective transformation (warp)?

#16Hey, this is great :) I attempted to do something similar a while back https://github.com/aadv1k/deimos basically trying to build many of OpenCV's functions from scratch in C from first principles, though I was using stb for handling the images. I ended up putting the project on hold, primarily because I lost interest in computer vision at the time. For a while I went deep into OCR, and built a rather rudimentary str…

Definitely on the todo list, but since it is only a side project, I don't know when I'll get to it. Any contributions would be highly appreciated! =)

https://github.com/spsingh37/Classical-computer-vision spend some time to understand how CV worked before deep learning transformed it in 2012->2014. lots of those techniques are still useful
This is very useful, I was unable to find a simple, clean implementation of the harris corner algorithm, this might help. Appreciate it!
