Buffering hierarchical representation of color video streams for interactive object selection

Abstract

Interactive video editing and analysis has a broad impact but it is still a very challenging task. Real-time video segmentation requires carefully defining how to represent the image content, and hierarchical models have shown their ability to provide efficient ways to access color image data. Furthermore, algorithms allowing fast construction of such representations have been introduced recently. Nevertheless, these methods are most often unable to address (potentially endless) video streams, due to memory limitations. In this paper, we propose a buffering strategy to build a hierarchical representation combining color, spatial, and temporal information from a color video stream. We illustrate its relevance in the context of interactive object selection.
