What is digital image Processing In java?

Answer 1

digital image processing means doing image manipulations

image data is normally stored in a 2d array so by manipulating this you can add filters, detect objects by identifying corners etc merge images in panorama

as a video is but a series of images, the same principles is applied which enables live tracking
