您可以对绿色和黑色图像进行逻辑与(&)，以告诉您它们重叠的位置.然后，如果需要连接的组件，则可以在生成的重叠图像上调用regionprops.

You can just do a logical AND (&) with the green and black images which will tell you where they overlap. Then if you need connected components, you can call regionprops on the resulting overlap image.

green_and_black = blackImage & greenImage;
overlap_props = regionprops(green_and_black, 'all')
