摘要：Noise present in the image hides necessary details. It compromises with level of quality of image. So, we need to remove the noise from images. Noise removal is one of the pre-processing tasks in several image processing techniques. Many researchers work on different types of filters used to remove different types of noises from images. There are some traditional filters, some filters derived from traditional filters and some filters are new innovations. In this paper, we make a survey on various denoising filters and conclude which works better among all.
