We propose a caption recognition method for multi-color characters on complex background. Caption characters are used for an efficient search on a large amount of recorded TV programs. In the caption character recognition, the caption appearance section and the area is extracted, the character patterns are extracted from the area, and recognized. This paper focuses on caption character patterns extraction and recognition for multi-color characters on complex background that conventional methods are difficult to recognize them. The proposed method extracts decomposed binary images from input color caption image by color clustering. Then character candidates that are composed of combination of connect components are extracted by using recognized certainty. Finally, characters are selected by beyond-color Dynamic Programming method in which weight on recognition certainty, character alignment, and continuity of color are used. In the character recognition evaluation of one-line multi-color character string on a complex background, a great improvement was achieved from a conventional technique that can recognize only one-color characters on complex background image. |
