伪彩色图像处理（a）实现图6.23，其特征是可以为输入图像指定两个灰度值范围，并且程序将输出RGB图像，其像素具有与输入图像中的一个灰度级别范围相对应的指定颜色，并且RGB图像中的其余像素与输入图像中的灰度阴影相同。
您可以将输入颜色限制为图6.4（a）中的所有颜色(b） 下载图1.10（4）中的图像，并使用程序处理它，使河流呈现黄色，其余像素与输入图像中的灰度相同。可以接受图像中也显示为黄色的隔离规格，但应尽可能少地保留这些规范，方法是正确选择输入程序的两个灰度带。
English Description：
Digital image processing experiment - image processing - with experimental topics and source code < p > pseudo color image processing (a) realizes figure 6.23, which is characterized by that two gray value ranges can be specified for the input image, and the program will output RGB image, whose pixels have the specified color corresponding to a gray level range in the input image, and the other pixels in the RGB image are the same as the gray shadow in the input image < p > you can limit the input color to all the colors in Figure 6.4 (a) (b) download the image in Figure 1.10 (4) and use the program to process it so that the river appears yellow, and the remaining pixels are the same as the grayscale in the input image. It is acceptable to accept the isolation specifications which are also yellow in the image, but these specifications should be retained as little as possible by correctly selecting two gray bands of the input program
