Design of graphics processing unit for image processing

Abstract

This work describes the designing of a Graphics Processing unit that deals with image processing. Graphics Processing Unit (GPU) is an important factor when it comes to large computing. Images and videos that are having large data can be processed efficiently in GPU by exploiting its feature of parallel execution. Digital image processing implemented on hardware provides higher processing speed and performance. The use of Verilog HDL for the design of GPU provides an immediate implementation possibility. The paper focuses on image processing operations like Brightness manipulation, Contrast manipulation, image cropping, image zooming, image rotation and morphological operators such as Dilation and Erosion.
