Image processing plays a vital role in plentiful fields

Image processing plays a vital role in plentiful fields, for example computer science, mathematics, optics, medical imaging, and industrial imaging. In computer vision its applications are also very diverse which include, remote sensing, feature extraction, pattern recognition, robot vision, finger print and face detection, argument reality, machine learning and many others. Therefore, digital images are of great importance when it comes to extract different kind of information out of images. So the need of digital image processing can be summarized as, the use of computer algorithms to:
Improve the pictorial information for human apprehension and Processing of data for storage, transmission and presentation for autonomous machine perception.
