opencv assertion fail

image description I first met the assertion fail in the function minMaxLoc , I am sure that there is nothing wrong with my input because I imwrite and check it successfully. image description Then I just guess the max and min values of instead of using this function , but another assertion fail happens. I get this project from my classmate, but it works normally in his computer with the same VS2015 and OPENCV 3.4.3 image description It costs me 2 days and I still can not find out why.
