What is digital image processing?

Digital Image Processing : An image which has a two dimensional function of f(x,y), where x and y are plane co-ordinates and the amplitude of f at any (x,y) is called the grey level of the image at that point. When the values of these of an image are finite, discrete quantities then the image is called a digital image. ... 

Digital image processing is the analysis of information contained in an image, usually by electronic means or using a computer which provides the analysis or recognition of objects in the image, etc. It may also enhancements, compression, segmentation etc.
