Hi, I´m gonna find the maximum and the minimum value of an image pixels: // ConsoleApplication1.cpp : Defines the entry point for the console application. //

include "stdafx.h"

include <iostream>

include <stdlib.h>

include <opencv2 core.hpp="">

include <opencv2 opencv.hpp="">

include <opencv2 imgcodecs.hpp="">

include <opencv2 highgui.hpp="">

int main() { Mat img1; double minVal, maxVal; int minLoc[2], maxLoc[2]; img1 = imread("DCIM_20171025_1.JPG"); namedWindow("Test Image", WINDOW_AUTOSIZE); imshow("Test Image", img1); waitKey(0); minMaxIdx(img1, &minVal, &maxVal, minLoc, maxLoc); printf("MAX= %d, MIN= %d", maxVal, minVal); getch(); return 0; } It seems pretty easy, but it doesn´t work! The program is compiled successfully, but there´ll be a run time error: Unhandled exception at 0x00007FF9E3EB9E08 in ConsoleApplication1.exe: Microsoft C++ exception: cv::Exception at memory location 0x000000C981CFF3C0. occurred Does anyone know how to solve this problem? Thank you
