Digital Image Processing

Digital image processing is the technology of applying a number of computer algorithms to process digital images. The outcomes of this process can be either images or a set of representative characteristics or properties of the original images. The applications of digital image processing have been commonly found in robotics / intelligent systems, medical imaging, remote sensing, photography and forensics.

Digital image processing directly deals with an image, which is composed of many image points. The image points, also namely pixels, are of spatial coordinates that indicate the position of the points in the image, and intensity (or gray level) values. A colorful image accompanies higher dimensional information than a gray image, as red, green and blue values are typically used in different combinations to reproduce colors of the image in the real world.
