What is the process for combining binary masks that represent different categories in semantic segmentation?

edit

The process for combining binary masks that represent different categories in semantic segmentation involves the following steps:

1. The binary masks corresponding to each category are generated using a neural network trained for semantic segmentation.

2. The binary masks are combined using a pixel-wise logical OR operation to create a single binary mask that represents all categories.

3. The resultant binary mask is then converted to a label image, where each pixel is assigned a label that represents the category it belongs to.

4. The label image is then visualized to show the segmentation results.

5. Post-processing techniques may be applied to refine the segmentation results, such as smoothing the boundaries or removing small isolated regions.
