一种印章图像的自适应特征提取算法

A adaptive feature extraction algorithm of seal image

分析了针对相似图像的几种特征提取方法的特点及局限性,提出了一种新的基于非线性回归原理的印章自适应特征提取算法.针对一组相似印章样本,通过相关分析和显著性检验,确定特征的优化选取,并给出了相应的算法描述,取得了令人满意的实验结果.

The features and limitations of some typical methods of feature extraction for similar seal images are analyzed, a new algorithm is presented for adaptive feature extraction of seal based on nonlinear regression theory. In order to recognize a group of similar seal patterns, the numbers of feature are optimized and chosen by correlative analysis and significance test. The result of the experiment is quite satisfactory.
