Digital Image Processing - A Remote Sensing Perspective

Digital image processing deals with manipulation of digital images through a digital computer. It is a subfield of signals and systems, but focuses   particularly on images. DIP focuses on developing a computer system that is able to perform processing on an image. The input of that system is a digital image and the system processes that image using efficient algorithms, and gives an image as an output. This paper discusses the various image processing techniques and remote sensing applications.
