Project Image Temporal Superpixels
In this paper, we develop a generative probabilistic model for temporally consistent superpixels in video sequences. Unlike supervoxel methods, the same temporal superpixel in different frames tracks the same part of an underlying object. Our method explicitly models the flow between frames with a bilateral Gaussian process and uses this information to propagate superpixels in an online fashion. We present four new metrics to measure performance of a temporal superpixel representation and find that our method outperforms supervoxel methods.

Code for our temporal superpixel (TSP) algorithm can be found here.

In the following video, we show some results obtained using our TSP representation.
