i am getting an error : 'CV_LOAD_IMAGE_UNCHANGED' : undeclared identifier i have included all d headerfiles as prescribed in the link. how can i debug this error

Answer 1

In OpenCV 3.0+ the flag names changed: http://docs.opencv.org/3.0.0/d4/da8/group__imgcodecs.html#ga288b8b3da0892bd651fce07b3bbd3a56

(check cv::ImreadModes)

The flag CV_LOAD_IMAGE_UNCHANGED is replaced by IMREAD_UNCHANGED

Answer 2

From version 4.0.0, CV_LOAD_IMAGE_UNCHANGED has been changed to:

    IMREAD_UNCHANGED
