Gradient image generator hardware/software co-design

This project proposes a software and hardware architecture for computing image gradients in order to reduce the input image size. The only way to transfer data in real time using lower speed wireless communication systems is to reduce the frame size; if a 24bit image is binarized the size will be re...
