DIGITAL IMAGE PROCESSING is the use of computer algorithms to perform image process on digital images. By using Digital image processing we enhance the digital images and extracting information and features from the image. Digital image processing has become the most common form of image processing and it is generally used because it is not the most versatile method but also the cheapest. This is the one type of image processing and it is used for filtering the image and editing the digital image which are taken from digital cameras. Digital Image Processing has the advantages as a wider
range of algorithm to be applied to the input data and can avoid the problems such as buildup of noise and single distortion during processing. The main feature of this technology. Digital image editing .Image Editors are providing the means for altering and improving images in an almost endless number of times. They accept images in large variety of image formats. The other features of this technology is image size alteration, cropping on images, removal of noise and unwanted elements, merging of images, colour adjustments and image filtering. Image filtering is another application of Digital image processing.
It is a computational intensive task requires large number of CPU cycles. In this paper the two methods of image filtering are explained and are compared. And in this paper we present categories of digital image processing, image compression, image viewing and image types, and digital image editing, and finally advantages and disadvantages of digital image processing.
