对图像的单个像素操作

自己总是忘记，做个笔记

static const Vec3b bcolors[] =

{

Vec3b(0,0,255),

Vec3b(0,128,255),

Vec3b(0,255,255),

Vec3b(0,255,0),

Vec3b(255,255,0),

Vec3b(255,0,0),

Vec3b(255,0,255),

Vec3b(255,255,255)

};

for(int x=0;x<gray.rows;x++)//gray为二值图

{

for(int y=0;y<gray.cols;y++)

{

if(gray.at<uchar>(x,y)==0)

{

img1.at<Vec3b>(x,y)=bcolors[5];//修改RGB值

Point p;

p.x=y;

p.y=x;

point.push_back(p);

}

}
