Refers to the analysis, processing, and processing of images to meet visual, psychological, or other requirements of the technology. Image processing is an application of signal processing in the field of images. At present, most images are stored in digital form, so image processing in many cases exponential word image processing. In addition, the treatment based on optical theory still occupies an important position.<br><br>Image processing is a sub-class of signal processing, and it is also closely related to computer science, artificial intelligence and other fields.<br><br>Many traditional methods and concepts of one-dimensional signal processing can still be applied directly to image processing, such as noise reduction, quantification and so on. However, the image belongs to the two-dimensional signal, compared with the one-dimensional signal, it has its own special side, the way and angle of processing is also different.
