Hey, 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 stroke width transform (https://github.com/aadv1k/swt.h) but again, the results were very hit or miss, likely because I never took the time to understand the logic behind why these functions would work.
1) Optimise many of the functions (a lot of room to use GPU, multi-threading and what not!). 2) Add new functions and improve the existing edge detection ones
I would love to know of a good resource for computer vision, the various algorithms, optimisation techniques etc. Thanks for sharing this project! Cheers

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!

Hey this is great! Thank you :)
Since 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.
I 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)?
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! =)
Did you see the "By The Power of Grayscale" submission and go digging?
Yes, that's exactly how I discovered it :-)

And then you said HEY YEYAAEYAAAEYAEYAA?
I’d like to take this moment to say that the recent She Ra revival series on Netflix by ND Stevenson (the creator of Nimona) is pretty good, go watch it.
On this tip I always found opencv to work way way faster just dropping the color depth of whatever image as such
Missed opportunity to one-up the He-Man joke from earlier :p
