1、Image Processing,Chapter 1Introduction,Digital Image Processing,What is digital image processing (DIP)?Digital images: A pixel has a location (the spatial coordinate) and a value.Digital images can be from many types of sources.Digital image processingDigital image processing is closely related to s
2、ignal processing at one end, and to computer vision at the other end.,Computer Vision,Computer vision:Computer vision is concerned with making computers “understand” what is contained in an image and other functions of human vision. It is sometimes considered to be a topic of artificial intelligence
3、. However, it is not possible to state exactly where image processing ends and computer vision begins.If you compare a digital image processing book and a computer vision book, you will find a lot of overlap.,Examples of Fields That Use Digital Image Processing,Energy of one photon,Gamma-Ray Imaging
