Dynamic semantic video compression and video indexing for interactive applications
- 技術優勢
- -- The software permits tuning of the video compression ratio and indexing in accordance with user needs; it is not restricted to using a fixed number of key frames.-- In contrast to some existing video indexing techniques, the technology can effectively index and compress videos with relatively unstructured content.-- The technology has lower time and storage requirements than cluster-based indexing schemes.
- 技術應用
- -- The technology can be used to stream video content over networks with variable bandwidths by dynamically altering the video compression ratio.-- The technology can be used to interactively browse and search through recorded videos.
- 詳細技術說明
- The technology is software for real-time dynamic compression and indexing of videos. The software employs a novel algorithm to summarize a video by discarding frames of low semantic importance while recording the significance and history of which fr...
