It is urgently needed to develop a solution to content based video retrieval

in order to support efficient management and quick browsing mass video data. Shot classification is an important research content in soccer video processing and retrieval. Considering the shortcomings of the existed methods

we propose a novel approach which can classify soccer video shots into main

middle

close up shots and other ones based on sub window region. The key step is to calculate the proportion of pixels with field color in sub windows region of soccer video frame in HSV color space. Experimental results have shown that the proposed method has a very high precision and recall rate.
