c++ opencv中table(1,256,CV_8UC3)更改为LUT(),通过三个通道进行显示


Mat table(1,256,CV_8UC3);
vector<Mat> bgr_planes;
split(table,bgr_planes);   //通道分离，生成bgr_planesp[1],bgr_planes[2],bgr_planes[3].
uchar *p=bgr_planes[0].ptr();
merge(bgr_planes,table);

------------------------------------------------------------------------------------------------------

#include "opencv2/opencv.hpp"
using namespace std;
using namespace cv;

int main()
{
        Mat table(1, 256, CV_8U);

        Mat a = imread("C:\\Users\\Administrator\\Desktop\\yingxiang\\tupian\\Lenna.jpg", IMREAD_GRAYSCALE);
        uchar* p = table.ptr();
        for (int i = 0; i < 256; i++)
        {
                if (i > 100 && i <= 192)
                        p[i] = 0;
                else
                        p[i] = i;

        }



        Mat b;

        LUT(a, table, b);
        imshow("NEW IMAGE", b);
        waitKey(0);

        return 0;

}


结合两段代码进行图片三通道显示。



跪求大神，万分感谢！！！！
