Image processing is a method to convert an image into digital form and perform some operations on it, to obtain an improved image or extract useful information from it. It is a type of signal dispensing in which the input is an image, such as a video or photo frame and the output can be an image or features associated with that image. In general, the image processing system includes the processing of images as two-dimensional signals while applying an already configured signal processing method.
It is one of the fastest growing technologies today, with its applications in various aspects of a business. Image processing is also part of the central research area within the disciplines of engineering and information technology.
