Image processing has many of the application in current scenario. During the image capturing or processing, some noise mix with the original image. Due to the noise issue the overall performance down or sometimes it failure. The images pixels mix with these types of the noise signal. There is various filters design which avoids or removes the noise signal. The advancement of the technology is going with the advance ICs processing. The VLSI architecture of filter design is useful in the FPGA ICs for the image processing applications. This paper reviews about the low-cost VLSI architecture of the filter for image denoising.
