OpenCV Resize Error: 'Assertion failed' - (-215) !ssize.empty() in function 'cv::resize'

This error message indicates that an assertion failed in the OpenCV function 'cv::resize'. Specifically, the error is caused by passing an empty size argument to the resize function.

To resolve this issue, you need to ensure that the size argument you are passing to the resize function is not empty. Check the code where you are calling the resize function and make sure that the size argument is a valid non-empty value.

If you are resizing an image, make sure that the input image you are providing is not empty or null. You can verify this by checking the size of the image using the 'empty()' function before calling the resize function.
