| Abstract: |
This paper describes a technique for generating partition sequences of regions presenting long-term homogeneity in color and motion coherency in terms of affine models. The technique is based on region merging schemes compatible with hierarchical representation frameworks and can be divided into two stages: Partition Tracking and Partition Sequence Analysis. Partition Tracking is a recursive algorithm whereby regions are constructed according to short-term spatio-temporal features, namely color and motion. Partition Sequence Analysis proposes the Trajectory Adjacency Graph (TAG) to exploit the long-term connectivity relations of tracked regions. A novel trajectory merging strategy using color homogeneity criteria over multiple frames is introduced. Algorithm performance is assessed and comparisons to other proposals are drawn by means of established evaluation metrics [1]. |
