FPGA based image processing unit

In the field of medicine, services based on multimedia and arts Image processing plays a crucial role. The important solution to enhance the quality of systems linked to image processing is hardware based processing of an image. In this a discussion about implementation of coin counting and simulated result by the help of a language for description of hardware, verilog was done. Algorithm for step wise implementation of Brightness manipulation, Operating Threshold and Contrast stretching is implemented which gives an efficient implementation than normal edge detecting kind of counting coins.
