| Abstract(in English) | Telop characters may be difficult to separate from the background because they are superimposed on the background image. On the other hand, character recognition methods by matching partial areas of the image to dictionary data repeatedly without separating the text and background take much processing time because of their high computational cost. This paper proposes an efficient matching method focusing on regularity of the arrangement of characters and same common features of the telop characters. First, the telop area is estimated by using density of color edge pairs. And then, midline position, the height and font type of the telop are determined by recognizing one character in the estimated telop area. Finally, each character of telop is recognized by minimum matching process. Our experiments using relatively large Gothic type telops of news TV programs confirmed that the proposed method can recognize characters at the recall and precision rate of 80 to 90 percent and at the processing time of about 0.5 second per input image. |
