Abstract
The present invention relates to a method for tracking at least one object in a sequence of frames, each frame comprising a pixel array, wherein a depth value is associated to each pixel. The method comprises grouping at least some of said pixels of each frame into several regions, grouping said regions into clusters (B1, . . . , B5) of interconnected regions; and determining that a cluster (B2, . . . , B5) which is adjacent to another cluster (B1) in a two-dimensional projection belongs to an object partially occluded by said other cluster (B1) if it has a different depth value than said other cluster (B1).
