Approach Overview

Input Image

Flower garden

Extract superpixels

flower garden sups



down
Obtain several spatiotemporal closure hypotheses using parametric maxflow

left
Build a graph with spatial and temporal affinities

spatial affinity



Superpixel Extraction

No temporal information
With temporal information
flower garden sups track flower garden sups track

The figures show a single superpixel tracked by following the temporal connections in the superpixel graph.
Using temporal information results in a more temporally stable superpixel segmentation (right) then if we don't use it (left).



Results

We test our algorithm on several videos. For each video, we show the original video and several solutions of interest.
For the car video we also show that shots can be detected by detecting minimas in global frame affinity.
