| 摘 要： | 该文根据台标的视觉特征，提出基于时空不变区域检测的方法来进行台标分割，并对台标特征提出用基于HSV颜色空间的加权Hu不变矩进行描述，最后采用基于知识库的方法进行台标识别。实验表明：该算法识别正确率较高，效果基本令人满意。

| Abstract: | According to the visual features of a TV station symbol, TV station symbol is segmented by the detection of spatio-temporal invariant region. The features of a TV station symbol are described with weighted Hu invariant moments in HSV color space and recognized on the basis of knowledge base. The algorithm is experimentally satisfying. |
