What do you mean by image processing? How it is differ from computer graphics?

Image processing

Image processing is a method to perform some operation on an image, in order to get an enhanced image or to extract some useful information from it. It is a type of signal processing in which input is an image and output may be an image or characteristics associated with that image.

major steps of image processing.

1. importing the image via image acquisition tools

2. analyzing and manipulating the image

3. output in which result can be altered image or report that is based on image analysis.

Difference between computer graphics and image processing.

The process of synthesize picture from mathematical or geometrical models is called computer grapics.

simply in computer graphics we take pixels as mathematical input parameters and draw different images from these pixels.

whereas the process of analyze picture to derive descriptions (often in mathematical or geometrical forms) of objects appeared in the pictures is called image processing.

image processing is the reverse process of computer graphics. where we take any one of the picture as input parameter and return their mathematical form.
