A Two-phase Video Keyframe Extraction Method
Hanhui Yang · Computer and Modernization · 2011
The keyframe extraction algorithm based on co-hisgram leads to the problem of missing extraction,while the method based on edge feature leads to the problem of high computational complex.The article proposes a method that takes advantages of the two algorithms,namely,first extracts key frames by using co-hisgram,then extracts the finally key frames from the previous results.Experimental results demonstrate that frames extracted can give a good summarization of the video while avoid redundancy.
