A Frame Quality Improvement before Video Shot Boundary Detection
Journal Title: International Journal of the Computer, the Internet and Management - Year 2016, Vol 24, Issue 3
Abstract
Video shot boundary detection is the first important step for the research in the following fields, automatic content analysis, content based-indexing and retrieval. In this paper, firstly the researcher presented, efficient method for video frame quality improvement to reduce noise, the flash-light problem and abrupt change illumination occurred within frame using logarithm transform with contourlet transform. Secondly, for shot boundary detection, we used gray-scale histogram differences with edge change ratio. Finally, we proposed the adaptive threshold algorithm based on a sliding window for shot transition detec-tion in order to get more accurate and precise detection. The experiment was then conducted on the standard video, and results are revealed that this pro-posed method can gain high precision and recall.
