9 Claims

1. A method of instance segmentation, comprising:

defining a bounding box;

depth mapping the bounding box;

sorting the depth map;

estimating stability due to noise of the sorted depth map;

detecting low frequency jumps of the sorted depth map based on the estimated stability;

detecting high frequency jumps of the sorted depth map;

comparing the detected low frequency jumps and the detected high frequency jumps;

detecting at least one of a largest object and a closest object based on the comparison; and

pixel masking the at least one of the largest object and the closest object.
