Digital Image Processing (DIP) deals with manipulation of digital images using a digital computer. It is a sub field of signals and systems but focuses particularly on images. DIP focuses on developing a computer system that is able to perform processing on an image. The input of such system is a digital image. The system processes the image using efficient algorithms, and gives an image as an output.

Java is a high level programming language that is widely used in the modern world. It can support and handle digital image processing efficiently using various functions.
