The difference between computer graphics and image processing lies in the overall definition. Computer graphics is mainly the synthesis technology of digital images, while image processing is the depth analysis and processing of images. The relationship between them is that digital image processing is the reverse process of graphics. In image processing, the main techniques include blurring, enhancing the contrast and graying degree of the image itself. Computer graphics, a mathematical algorithm Computer graphics is a simple mathematical algorithm, which mainly converts two-dimensional and three-dimensional images into a grid format that can be displayed by a computer. Through the description of the virtual scene, a multilateral image is formed, each image consists of three vertices, displaying three-dimensional coordinates and maps. , specifically the output of images, called two-dimensional pixel group display.

Digital image processing, image calculation Digital image processing refers to a kind of deep processing of digital images. Digital computers can be used to budget the algorithm, focus on the changes of images, carry out narrow processing on images, solve the visual effect of images, adjust the external aesthetics of images, and play a certain enhancement effect. The use of technology is to realize the deep compression of images and the release of storage space, reduce the compression of image transmission time, and further meet the requirements of fixed transmission channels. Digital images are digitized while ensuring the correctness of the manuscript, and images are always copied in the process of digitization.

Graphics is the predecessor of image processing, and there is a correlation between them. Computer graphics and image processing are related, and image processing can be regarded as the reverse process of computer graphics. Both of them are superimposed on the technology to increase the late special effects, and the calculation amount is placed on the top of the graphics card. Image processing depends more on technology, and photos should be identified and preprocessed later. DIP technology can be used for tracking, and CG virtual TM superposition can be used to make the image more realistic.

Especially suitable for making some game animation images. Graphics can be framed first, and then image processing can be operated later, so as to achieve good decorative effect.

The difference between graphics and image processing is that computer graphics and image processing are very different in different internal sequences, which is embodied in that graphics itself pays attention to a description of scenes, and each scene is composed of multilateral arrays, including three-dimensional coordinates, rgb colors and so on. Under the interaction of these * * *, a pixel map group comes out. But image processing is the deep processing of the basic image, and the operated image comes from camera, lens or some video files. The output image corresponds to the real world. Common operation skills are dark gray and blurring.

In a word, there are great differences between computer graphics and image processing in definition and corresponding technical processing. The former is a pixel map, and the latter is a stereoscopic map. The latter's technical skills include PS, gray scale, background contrast and so on. In order to make the picture clearer and the contrast higher.
