If my figure has two axes/subplots and one of them plots an image, how can I use imcrop on that image and plot the cropped image in the other axis/subplot?

Ideally, the plot of the cropped image in the second axis/subplot will update as I adjust the rectangular cropping tool used on the image in the first axis/subplot.

在 MATLAB Online 中打开

cropped_version = imcrop(handle_of_first_axes);
imshow(cropped_version, 'Parent', handle_of_second_axes);

This will not update as you adjust the crop tool.

For interactive cropping, imcrop calls the undocumented internal toolbox/images/imuitools/+iptui/imcropRect.m which you could copy and hack for your own purposes (but it might rely on other tools in +iptui )
