Digital image processing refers to a process of converting an image signal into a digital signal and processing it with a computer. Image processing was first in the 50's of the 20 th century, and electronic computers were developed to some extent, and people began to use computers to process graphics and image information.
Digital image processing was formed as a discipline in the early 60's of the 20 th century approximately. The purpose of early image processing was to improve the quality of images, which were targeted at human subjects with the goal of improving human visual effects. In image processing, an image with low quality is input, an image with improved quality is output, and common image processing methods include image enhancement, restoration, encoding, compression, and the like.
For example, image coding compression techniques may reduce the amount of data (i.e., the number of bits) describing an image in order to save image transmission, processing time, and reduce the amount of memory occupied. The compression can be obtained without distortion or can be carried out under allowable distortion conditions. Coding is the most important method in compression technology, and it is the earliest and more mature technology in image processing technology.
