Title Requirements:

Use the mask generated by exercise 6. Load a location map and use this mask in cvcopy:

A, copy the location map to a new image, copy only the portion of the mask that has a value not equal to 0.

B. Copy the mouse image to the location image.

Cvcopy Use precautions: must ensure that the input image, output image, mask image roi, COI type and size of the same, or error, you can set the area of interest to achieve this purpose
