中文说明： 数字图像处理（Digital Image Processing）又称为计算机图像处理，它是指将图像信号转换成数字信号并利用计算机对其进行处理的过程。第一台可以执行有意义的图像处理任务的大型计算机出现在20世纪60年代早期，人们开始利用计算机来处理图形和图像信息，数字图像处理作为一门学科大约形成于20世界60年代初期。早期的图像处理是改善图像的的质量，它以人为对象，以改善人的视觉效果为目的。图像处理中，输入的是质量低的图像，输出的是改善质量后的图像，常用的图像处理方法有图像增强、图像复原、图像编码、图像压缩等。
English Description：
Digital & nbsp; image & nbsp; processing, also known as computer image processing, refers to the process of converting image signal into digital signal and processing it by computer. The first large-scale computer that can perform meaningful image processing tasks appeared in the early 1960s. People began to use computers to process graphics and image information. Digital image processing as a discipline formed in the early 1960s. The early image processing is to improve the quality of the image, it takes people as the object, to improve the visual effect of people as the purpose. In image processing, the input is the image with low quality, and the output is the image with improved quality. The common image processing methods include image enhancement, image restoration, image coding, image compression and so on.
