Introduction • What is Digital Image Processing? Digital Image — a two-dimensional function x and y are spatial coordinates The amplitude of f is called intensity or gray level at the point (x, y) Digital Image Processing — process digital images by means of computer, it covers low-, mid-, and high-level processes low-level(DIP): inputs and outputs are images – reduce noise, image enhancement, sharpening etc mid-level(Image Analysis): outputs are attributes extracted from input images – edges, contours etc high-level(CV): an ensemble of recognition of individual objects Pixel — the elements of a digital image Element refers to locations having a finite discrete value 12/31/2021 7
