Computer manipulation of images is generally defined as Digital Image Processing (DIP). DIP is used in variety of applications, including video surveillance, target recognition, and image enhancement. These applications are usually implemented in software but may use special purpose hardware for speed. With advances in the VLSI technology hardware implementation has become an attractive alternative. Assigning complex computation tasks to hardware and exploiting the parallelism and pipelining in algorithms yield significant speedup in running times. In this thesis the image processing algorithms like median filter, basic morphological operators, convolution and edge detection algorithms are implemented on FPGA. A pipelined architecture of these algorithms is presented. The proposed architectures are capable of producing one output on every clock cycle. The hardware modeling was accomplished using Handel-C (DK2 environment). The algorithm was tested on standard image processing benchmarks and the results are compared with that obtained on software
