What was measured

Edge quality

How clean are the cutouts around hair, fingers, and clothing edges; are there visible halo, fringing, or jagged edges?

decisive for this rankingtransformation

Clean edges around hair, fingers, and clothing are a core measure of whether the background cutout works well at all. (3 of 3 judges)

What was given, what came back

Test input: Busy Urban Street · video · group: remove-or-replace-video-backgrounds-using-ai

Input — what we sent

A video of a person walking through a busy city street with multiple people, moving vehicles, and a visually complex urban background. It was used to stress segmentation and tracking under heavy background distraction and continuous motion.

Why this input is hard

· Complex background segmentation
· Handling background distractions
· Subject tracking
· Temporal consistency across frames
· Edge accuracy during continuous movement

Output — unretouched

Hair and fine detail⚠ StruggledBakes falling snow into the foreground mask as static speckled texture.Motion handling✓ WorkedKeeps a moving foreground pedestrian isolated while the background stays removed, and even a second person can appear as a separate cutout in one frame.Output resolution⚠ StruggledDownscales the roughly 1080×1920 source to 360×640 and truncates a 20.02s clip to 5.005s.
