Insertion Sort Circuit Design Applied on the Median Filter

摘要

In our paper, we proposed the insertion sort circuit of the median filter for the corrupted image. The median filter can be overcome the salt-pepper noise in the figure. We indicate the middle pixel value in a mask window of the figure to overcome the salt-pepper noise occurred. The method concept is easy and efficient. We use the Altera DE2-115 development board to verify our insertion sort circuits. We put the noise image in the SDRAM on the board, and filtered the image by the proposed circuits. In the result, we display the picture on the screen to show the processed image.
