In digital image processing, the same image shall be fed in as an input to the system and the system shall interpret and understand the content to let the further actions happends.
the algorithms developed shall play a major role in understanding the content with higher accuracy.
"Optical image processing is an area that deals with the object, optics and how processes are applied to an image that is available in the form of reflected or transmitted."
"Analog image processing is an area that deals with the processing of analog electrical signals using analog circuits. The Imaging systems that use film for recording images are also knows as analog imaging systems.
