alt Hacker NewsIt was fun trying out the demo, with the "coffee kettle pouring" video it did really well segmenting the man's hand and arm and tracking it (segmenting them in every frame correctly), but with the "Find the ball cup game" video it lost track of the tracked cup in a strange way, it kept track of it correctly while it went behind other cups, but after it wasn't occluded anymore, it switched to an other cup.
It's still impressive to me how it twice kept track between occlusions, but strange how it lost track when it wasn't occluded.
Selected the left hand of the guy (hand on the right from our perspective) dribbling the soccer ball and it ends up highlighting both arms after a mid-point frame where the left arm is only partially occluded by his body. Very interesting that it will go from tracking a single discrete object to multiple discrete objects.
