c++ - 无法在 OpenCV 中打开 1 位二进制图像？

Question

如果我检查空图像，它在使用 imread 读取二进制图像时返回 true

original_img = imread("E:/Newfolder/ER41615-12.TIF",  CV_LOAD_IMAGE_ANYCOLOR );

Answer 1

来自doc

The function imread loads an image from the specified file and returns it. If the image cannot be read (because of missing file, improper permissions, unsupported or invalid format), the function returns an empty matrix ( Mat::data==NULL ).

Mat::empty() 将返回 true。
