The Programming for Color Image Processing Based on Color Space
Abstract: In this paper, two common color spaces, RGB and HSI, are mainly discussed which contraposing the color space processing of color image, and analyzed various principles and algorithms of image processing base on these two kinds of color spaces, used C# language to do programming. Memory method is used in programming of image processing, namely copy image data into memory directly, in order to obtain faster processing speed. The program of color space conversion is designed to do component transformation firstly, and then turned each component into gray space, thus outputted the gray scale images; component adjusting is an important application base on the principle of color space conversion, disposed each component of color space respectively, then outputted color image after processing. In the practical application, among different color spaces often need to covert, the requirement of conversion is as well as in constant increase, such as stability, efficiency, cost, etc. In the paper, the principles, algorithms and processing methods have been discussed, also made some improvements, and achieved good effect in the experiment.

1 数字图像处理概述
图像是最基本的媒体表现形式，图像通过丰富的色彩属性、逼真的轮廓线条等使其携带了丰富的信息，能够更形象、直观的进行信息传播，是一种广泛使用的媒体表现形式。数字图像不仅具有普通图像的共同的表达特性，同时由于其独特的表现、存储与传输技术使其具有更丰富的表现空间、安全的存储以及快速地传输特征，是数字媒体表现形式中不可或缺的媒体形式。
