opencv 文档 指出: namedWindow flags – Flags of the window. Currently the only supported flag is CV_WINDOW_AUTOSIZE . If this is set, the window size is automatically adjusted to fit the displayed image (see imshow() ), and you cannot change the window size manually. 但是qt 后端显然有...
CV_WINDOW_NORMAL enables you to resize the window CV_WINDOW_AUTOSIZE adjusts automatically the window size to fit the displayed image and you cannot change the window size manually CV_WINDOW_FREERATIO adjusts the image with no respect to its ratio CV_WINDOW_KEEPRATIO adjusts the image keeps ...

Passing CV_WINDOW_AUTOSIZE to namedWindow() will make the window size automatically adjust to fit the displayed image. And you see part of the image is probably because the image is too large for your screen. To work out, you can first resize the image to smaller size. Like this: Mat ...

very good effect from the optimized resize(...,INTER_AREA) is observed. Would be nice to integrate it before 4.9.0 release. keep working on OSS-fuzz-based testing of OpenCV (avif codec and other parts). input from Dmitry: maybe G-API could be useful for massive image processing; see ...
