Text in video can provide an important supplemental source of index semantic information. In this paper

an algorithm of automatic video text locating

tracking and recognition is presented. First

the text regions are located by several steps: wavelet decomposition

high frequency component intensity and density detection

horizontal and vertical convex detection based LH

and text locating. Then the text regions are tracked in next consecutive frames. After multiple frames averaging

the text regions are enhanced. By binarization of the enhanced text regions followed by component analysis

the text regions with clean background are obtained. Then the text regions are recognized by OCR software

the final text strings are attained. Experimental results show that the proposed algorithm can detect and track text region simply and effectively.
