How to Remove mouseCallback in OpenCV

c++, mouseevent, opencv

Solution

Set the window callback function to `NULL` like this:

cv::setMouseCallback("image_window", NULL, NULL);

Problem

In OpenCV with C++, Is there a way to remove the ``` mouseHandler(int event, int x, int y, int flags, void* param) {} ``` added to a window "image_window" by function ``` cv::setMouseCallback("image_window", mouseHandler, (void*)param); ``` Thanks for your advice! :-)
