System of locating and recognizing characters in complex background

In this paper we propose a locating and recognizing character method in complex background, a system based on this method is built. First, through color reduction to reduce the color to some main colors, then decompose the image into a series of binary images according to the representative colors. After the image decomposition, connected component analysis and combination of character area are used to locate the character area. Finally, the characters are recognized on the basis of feature extraction. The experimental results show that the method can quickly locate character area and has a high positioning accuracy; therefore, the final recognition rate is high.
