title = "Circular Viterbi based adaptive system for automatic video object segmentation",
abstract = "Many future video standards such as MPEG-4 are shifting focus from compression to content; video object segmentation is the key technology required by these standards. Unlike still images, motion in video can be used to discriminate between objects. We present an automatic video single object segmentation system whose core is the adaptive version of the circular Viterbi algorithm. The circular Viterbi algorithm fuses the information from motion analysis, edge analysis, active contours (dynamic snake), and temporal correlation into a unified system. Results of pixel-resolution boundaries from our system are shown. Analysis of results, the integration of human-guided data and region-based analysis and a future iterative scheme for multiple object sequences are also discussed.",

Complete results are available in HTML version. CONCLUSION Our system represents a new paradigm for object segmentation and has much room for improvement. More accurate true motion estimator and edge operators would improve performance. Integration of object region-based methods can compensate for or enhance the current edge-based motion analysis. For a semi-automatic system, temporal training can be guided by human input through either direct information or high confidence edge images. The simple smoothing constraints can be upgraded to more complete model of object motion. Analysis of stability and convergence of temporal training is needed as well. Using this system as a basis, we continue this work in an iterative method of multiple object boundary segmentation. ACKNOWLEDGMENTS This research was funded by Mitsubishi Electric ITA Adv.
