Abstract

This paper proposed a method for extracting Chinese characters in a gray scene image. This method makes use of the general features of. Chinese characters in scene image. First, the scene image is divided into partial regions. Some regions can be set as candidates of character regions with comparing spatial frequency and contrast. Then, the whole image is binarized using the dynamic thresholding method of gray-level image. Next the circumscribed squares of each candidate character regions are located according to the labeling results. Finally, the character regions are determined using the proximity of characters, co-linearity of characters and similarity of characters. The extraction rate is about 80.6% according to the experiments.
