OpenCV Error: Assertion failed (size.width＞0 && size.height＞0) in cv::imshow

如果在使用Opencv的过程中出现OpenCV Error: Assertion failed (size.width>0 && size.height>0) in cv::imshow, file …\opencv\modules\highgui\src\window.cpp, line 261，则是文件路径有误，
应将Mat img = imread(“D:\pics\test.png”);
改为
Mat img = imread(“D:\\pics\\test.png”);

 bug扫除了，要不鼓励我一下吧
