Hardware acceleration for image processing

This project implements a hardware acceleration system for image processing primitives on a FPGA. The system processes in real-time a stream of images, coming for example from a webcam.
The framework stays limited to greyscale images and implements the following operators:

• Identity oprator
  
• Gaussian filter
  
• Median/Min/Max filter
  
• Gradient magnitude and phase
  
• Non-maxima elimination
  

The C code allows the final user to call these primitives without being aware of any link with hardware. The OpenCV library was used for performance comparisons with software.
