| Abstract(in English) | An algorithm for the extraction of character strings from a color document is proposed. We first divide the full color image into several representative color images. Then, character strings are nominated from each binary image by using multi-stage relaxation. However, the nominated strings are not always characters. They may be a part of the background, concatenated holes of characters or dotted lines, etc. Therefore, when all nominated strings of all images are superimposed, some strings overlap each other. So, we selected the appropriate strings from them using a likelihood of a character string and two kinds of conflict resolution. In the experiments, we used color images input from magazine covers, posters, etc. We show the experimental results and discuss some problems of character string extraction from a color document. |
