Implementing image processing algorithms in VHDL is a scary thing for many. Though I agree that its much more difficult to do it in VHDL than in a high level programming language like C, Matlab etc, it needn't be that scary. In this post I am going to share the code for a simple image processing algorithm - A RGB to Gray scale image converter.
