You can even name them one by one, providing labels. Additionaly, why do you create 2 masks? I took an approach of successively adding each image to the next, if the value of any resulting pixel is equal to the sum of classID of object #1 and classID of object#2, it indicates an overlap, and I set those pixels to the value of classID #2. It involves merging, blocking, and separating an image from its integration level. Why was the nose gear of Concorde located so far aft? How can I access environment variables in Python? If you are sure of you masks. The problem comes when I try to do this with a segmentation overlay. Although image segmentation annotations come in a lot of different types (such as semantic segmentation, instance segmentation, and panoptic segmentation), the practice of image segmentation generally describes the need to annotate every pixel of the image with a class. When creating image segmentation masks, it's important to be able to share borders between objects.
