说明：  本实验要求编写程序实现课本图6.23伪彩色图像处理能力框图，实现灰度级到彩色的转换，程序的输入为图像中指定的两个灰度级范围，程序的输出为RGB格式图像，其中一个灰度级范围显示为指定的彩色，其余的像素以RGB形式显示为与对应输入图像像素相同的灰度色
(Prepared at the request of the experimental procedures to achieve pseudo-textbook Figure 6.23 Block diagram of color image processing capabilities to achieve gray-scale to color conversion, image input process as specified in the scope of the two gray-scale, the program output for the RGB format images, one of which range of gray-scale display for the specified color, and the rest of the pixels in RGB and the corresponding form for the same input image pixel gray-scale color)
