[opencv]图像预处理方案及方式

 

Mat hsv;
    cvtColor(transmat,hsv,COLOR_BGR2HSV);
    Scalar lower_white (0,0,0);
    Scalar upper_white (180,255,180);
    Mat mask_white;
    inRange(hsv,lower_white,upper_white,mask_white);

    Mat gray = mask_white;
    threshold(gray,gray,100,255,THRESH_OTSU + THRESH_BINARY);

//    cvtColor(transmat, src_gray, COLOR_BGR2GRAY);
//    src_gray = Scalar::all(255) - src_gray;
//
//    blur(src_gray, src_gray, Size(3, 3));
//    equalizeHist(src_gray, src_gray);
//    imshow("滤波后", src_gray);
//    imwrite("/home/leoxae/KeekoRobot/TestPic/blur2_2.png",src_gray);
//    waitKey();
