In this study, the difference between parallel programming and serial programming and the differences between whole image processing and image processing by segmentation was tried be to analysed. In the context of the study, to the image given to the application, which improved with Net framework, median, mean and gauss filters were applied by using single, double and 4 as a separate part serial programming and parallel programming methods. As a result of the study experienced in different computers and processors, it was noticed that parallel programming method performed filter processing in a shorter time both in the whole image and the segmented image. We determined that the whole image processing has higher performance than other method for image.
