FlatCV

Simple image processing and computer vision library in pure C.

"Simple" means:

• Color images are a flat array of 8-bit per channel RGBA row-major top-to-bottom
• Grayscale images are a flat array of 8-bit GRAY row-major top-to-bottom
• All operations are done on the raw sRGB pixel values
• Minimal usage of macros and preprocessor
• Available as an amalgamation where all code is combined into one file.
  (Each release includes a flatcv.h and flatcv.c file.)
• No fusing of image transformations
• No multithreading
  You're more likely to process one file per core than one file over multiple cores anyways. Yet, it's still often faster than GraphicsMagick with multiple threads. (See benchmark below.)
• No GPU acceleration
• Only uses functions from the C standard library.
