伪彩色处理是指将黑白图像转化为彩色图像，或者是将单色图像变换成给定彩色分布的图像。由于人眼对彩色的分辨能力远远高于对灰度的分辨能力，所以将灰度图像转化成彩色图像表示，就可以提高对图像细节的辨别力。

伪彩色处理的基本原理是将黑白图像或者单色图像的各个灰度级匹配到色彩空间的一点，从而使单色图像映射成彩色图像。对黑白图像中不同灰度级赋予不同的彩色。

-Pseudo-color processing refers to the black-and-white images into color images or monochrome images will be converted into the distribution of a given color image. Since the human eye to distinguish color of gray is much higher than the resolving power, it will be gray-scale images into color images that can improve the discriminability of image detail. Pseudo-color processing is the basic principle of single-color or black and white images of various gray-scale image to match that color space, so that monochrome images into a color image mapping. Black and white images of the different gray-scale to give a different color.
