These 4 segmented 2-D arrays are segmentations of different objects present in one image. Is there any better implementation? Assuming fused_mosaic is the 2D integer array we discussed earlier, flatten this array and index your colour map: output = cmap [fused_mosaic.flatten ()] Step #3 - Reshape to the desired output This again is straight forward: Pre-labeling decreases labeling costs as the model gets smarter with every iteration, leaving teams more time to focus on manually labeling edge cases or areas where the model might not be performing as well. To overlay an image segmentation with numpy, we can take the following Steps . It is required to overlay all these segmentations of different objects into one image instead of having 4 separate segmented images.
