基于MATLAB的特定前景图像分离，将车辆识别并分离出来的第二种方法——通过图像的RGB线性变换的像素操作分离背景

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。
