CATER (moving camera). Note the object occluded (the distant yellow sphere) for some frames in example 2; it is tracked stably by SIMONe. Moreover, SIMONe assigns each object's shadows (up to three due to multiple lights) to the same segment.
Playroom. Number of unique foreground objects across the sequence in each example: 28, 15, and 29.
