摘要
数字图像处理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。图像处理最早出现于20世纪50年代,形成学科于20世纪60年代初。早期图像处理的目的是改善图像的质量,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、复原、编码、压缩等。认识数字图像处理技术对以后的教学研究有着积极的作用。
Digital image processing is the image signals into digital signals and use computer to process.Image processing first appeared in the nineteen fifties,forming the discipline in the early nineteen sixties.Early image processing is to improve the image quality.Purpose is to input is low quality image,the output is to improve the quality of images,commonly used image processing methods are image enhancement,restoration,coding,compression.Knowledge of digital image processing technology for future teaching research will play a positive role.
