Abstract:

The digital image processing (or DIP) is done to get an enhanced or filtered image or to extract any required information from the image by manipulating it. A raw image is converted into a digital image using various algorithms and machinery. DIP is one of the swiftly emerging technologies. It forms key sector for research within computer science and engineering field. It has made its way in a wide variety of fields ranging from medical to space. There are various steps involved to process a digital image and to obtain desired outcomes. In this paper we have discussed the detailed review about the digital image processing, image filtering, its recent trends and challenges faced.
