Abstract:

The research on the character segmentation of the horizontal caption line in news images was made in this article. In order to overcome the character splitting problem caused by existing single character based segmentation methods, a response function was proposed based on character distribution. The character segmentation problem is converted into an optimal problem, and the character segmentation can be attained by turning to the optimal result. The algorithm mainly contains two parts:First, the rough width of a single character is determined based on the vertical projection histogram, which is utilized to construct a variable length template; Then, the template response function is constructed and the left/right boundary position of a single character is determined by the optimal value of the response function of different length templates; Last, output the segmentation results. Experimental results show that the proposed method can obtain satisfactory results for adhesion/non-adhesion character images.

Key words: news images, captions, template matching, character segmentation
