Signal processing is a discipline in electrical engineering and in mathematics that deals with analysis and processing of analog a digital signals , and deals with storing , filtering , and other operations on signals. These signals include transmission signals , sound or voice signals , image signals , and other signals e.t.c.

Out of all these signals , the field that deals with the type of signals for which the input is an image and the output is also an image is done in image processing. As it name suggests, it deals with the processing on images.

It can be further divided into analog image processing and digital image processing

Digital image processing has dominated over analog image processing with the passage of time due its wider range of applications.

Digital image processing the digital image processing deals with developing a digital system that performs operations on an digital image.
