Title:
MULTI-LEVEL PARALLEL KEY FRAME CLOUD EXTRACTION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/086731
Kind Code:
A1
Abstract:
Disclosed are a multi-level parallel key frame cloud extraction method and system. The key frame cloud extraction system comprises: a video input module, configured to be a video input port for extracting the key frames; a video lens segmentation module, configured to perform a lens segmentation on the inputted video to facilitate a parallel processing of the key frames extraction; a multi-level parallelism key frame cloud processing module, configured to generate sets of the key frames of each lens by performing on the video lens a parallel-extraction of a frame feature vector and a parallel-clustering via a multi-level parallel policy; a key frame output module, configured to combine the sets of the key frames generated by each lens, and lastly output the sets of the key frames of the entire video. The multi-level parallel key frame cloud extraction method and system in the present invention has a higher efficiency in processing large-scale key frame extraction, an excellent scalability and stability, and meets the need of the large-scale key frame extraction.
