Performance Analysis of Basic Image Processing Algorithms on GPU

摘要

Image processing could be done in CPU or in Graphical Processing Unit (GPU), using sequential programming or parallel programming respectively. Sequential and parallel programming are good in their own paradigm. This paper analyses the performances of various basic image processing algorithms on GPU as well as CPU. Various images with a range of dimensions have been used for the testing purpose. The results show that the usability of the GPU for image processing problems is highly depends on the nature of the problem and also on the size of the problem domain.
