Abstract

In this paper, an address block segmentation approach based on fractal dimension FD is proposed. After computing the fractal dimension of each image pixel by the 2D variation procedure, a clustering technique based on K-means is used to label pixels into semantic objects. The evaluation of the efficiency is carried out from a total of 200 postal envelope images with no fixed position for the address block, postmark and stamp. A ground-truth strategy is used to achieve an objective comparison. Experiments showed significant and promising results. By using the 2D variation procedure for three ranges of neighbor window sizes (r= {3,5}, r= {3,5,7}, and r= {3,5,7,9}), the proposed approach reached a success rate over than 90% on average.
