Question about mask

[Eric031212]

I found that in your training code had mentioned about the motion mask. What is that used for? Calculate the moving part or just segment the scene.

motion_mask is a learned attribute in SC-GS that indicates whether a Gaussian is dynamic or static. By applying motion mask supervision or a binary constraint (with argument --gt_alpha_mask_as_dynamic_mask --gs_with_motion_mask), you can achieve adaptive segmentation of dynamic and static components.
