　　报告摘要：Image processing is a method to perform some operations on an image, in order to get a processed image or to extract a set of characteristics or parameters from it. It is among rapidly growing technologies today, with its applications in various aspects of astronomy and space science. As raw data from imaging sensors from ground-based or space-based telescopes contains deficiencies. To get over such flaws and to get originality of information, it has to undergo various phases of processing. The three general phases that all types of data have to undergo while using digital technology are pre-processing, enhancement and display, information extraction. In this talk, I will talk about some essential definitions and information about image processing. Different applications of image processing methods in solar physics will be discussed and examples for each application will be provided. Finally I will give a brief introduction about how to build an image processing system.
