Abstract

Representative frames are vital and attractive key components in providing Internet users a way to swiftly browse a video clip in different levels of detail, without the need to view entire video clip. Past study reveals that several schemes have been developed for representative frame extraction however all schemes are not decorating the key frames. This paper proposes a new concept called Representative Frame Decoration (RFD), in which the essential operation is to enhance the key frame of a video shot. Our approach employs an unsharp mask filter to enhance contrast and sharpen edges of the elements without increasing noise or blemish. Experimental results of representative frames existing on internet illustrate the high performance of the proposed schemata.
