Skeleton-based supplementation for foreground image segmentation

A system for foreground image segmentation, the system comprising:

• an imaging camera configured to capture image data at a first time;
• a skeleton model generator configured to generate a skeleton model of a foreground subject captured in the image data;
• an initial foreground mask generator configured to generate an initial foreground mask for a foreground segment including the foreground subject;
• a secondary point generator configured to generate a first plurality of secondary points corresponding to the foreground subject;
• a foreground segmenter comprising:
• a skeleton-based reconstructor configured to identify supplemental points for the foreground segment based on at least the first plurality of secondary points and the skeleton model, and
• a foreground mask combiner configured to combine the supplemental points with the initial foreground mask to obtain a combined mask,
• wherein the foreground segmenter is configured to obtain a foreground segment mask for the foreground subject based on the combined mask;
• and
• wherein the skeleton-based reconstructor is configured to reconstruct an estimated edge of the foreground segment mask based on at least the first plurality of secondary points;
• and
• a foreground image generator configured to apply the foreground segment mask to the image data to obtain a foreground image portion for the foreground subject.
