推荐答案

确保图像文件格式是受支持的类型之一(

Make sure the image file format is one of the supported types (http://docs.opencv.org/modules/highgui/doc/reading_and_writing_images_and_video.html#imread). Also ensure that the filepath given as the argument is correct. You could also use drag & drop the image on the executable file.
