Abstract: The authors propose a simple but effective distance based method to identify forms with similar layouts by measuring the user filled-in data, preprinted data and dithering data. The proposed method utilizes three kinds of weight components to mitigate the impact of randomness of user filled-in data, consistency of similar layouts and position dithering respectively. Experimental results show that the proposed method can achieve more than 90% classification accuracy on a series of data sets, which is significantly better than the results of the state-of-the-art method.
