摘　　要：针对印鉴识别任务中有效印文的提取以及伪造印鉴的识别这两个难点问题,建立在监督分类体系下的印鉴识别系统。利用有效印文与背景的颜色统计差异以及真伪印鉴间的几何统计差异分别解决上述难点。在构建的包含3000个印鉴的印鉴数据库上进行实验,实验结果表明,该方法对于有效印文的提取准确率可达到(95.27±3.73%),对于伪造印鉴的识别准确率可达到97.62%,具有可行性和有效性。To solve two challenging problems of the seal imprint identification including the valid seal prints extraction and the forged seal identification, a new seal identification system was designed under a supervised classification framework. Based on the statistical color difference between seal prints and the background, and the geometric difference between the real and the forged seal, a novel seal extraction method and a novel forged seal identification method were proposed respectively. Results of the experiment performed on a challenging real seals database show that the proposed method obtains the good performance in terms of the valid seal prints extraction （95.27 ±3.73%）and the forged seal identification （97.62 %）.
