This paper introduces HSV color space and an algorithm of automatic recognition character color.By using background subtraction technique and color analysis methods,the positions of characters are found,and characters are segmented with projection algorithm.BP neural network is applied in characters recognition to identify the number 0 to 9.Experimental results show that the proposed scheme is feasible and has great robustness.
