如果运行不通，可尝试不直接点击“运行”，而是点击“运行并前进”按钮。 这个MATLAB函数将灰度图像I中的强度值映射到J中的新值，使得1%的数据在I的低强度和高强度下饱和。对图像f中任意像素的灰度值x进行变换，得到图像f 中对应像素的灰度值XF。 具体的算法步骤如下： i. Set adjustment linearity value; ii. Read in the image to be processed and assign it to I; iii. Assign image data to R. Change the original image into a monochrome image and keep the red color. Use the function imadjust to adjust the gray level of R, and the result returns R1; iv. Assign image data to G. Change the original image into a monochrome image and keep the green color. Use the function imadjust to adjust the gray level of R, and the result returns G1; v. Assign image data to B. Change the original image into a monochrome image and keep the blue color. Use the function imadjust to adjust the gray level of R, and the result returns B1; vi. Get RGB image after transformation; vii. Draw R, R1, G, G1, B, B1 images and observe the results of linear gray-scale transformation. 结果一般。 版权声明：本文为CSDN博主「灵泉matlab」的原创文章，遵循 CC 4.0 BY-SA 版权协议，转载请附上原文出处链接及本声明。 原文链接：https://blog.csdn.net/qq_31434537/article/details/104562388
