The authors propose a novel algorithm for the video caption extraction.By using the image sharpening method,a better extraction effect can be achieved for the special video sequences.The caption area and the non-caption area can be efficiently separated by neighborhood average operation.A projection algorithm is proposed to implement on a better decomposition and extraction based on the statistical characteristics,and this can efficiently separate the caption area and make the extraction coordinates more precise.The experiments show that the proposed algorithm has a better effect compared with the original methods.Because of the low computational complexity,it can be widely used in the field of video image processing.
