Abstract: In pattern recognition, the effect of binarization directly affects the recognition rate. In the foundation of binarization algorithms research, the paper improves the multi-threshold and dynamic binarization algorithm. Taking example for ID card, it validates the effect of this algorithm. Experimental result indicates that the proposed method has better capability of anti-noise.
