| 摘 要： | 子空间法作为一种传统的识别方法,识别时基于整幅图像,复杂性比较高,而且没有考虑类别信息.为了降低计算复杂性和在提取数据特征的同时融入类别信息,研究了一种基于小波变换和部分最小二乘(PLS)的掌纹识别算法.在建议的识别方法中,首先通过小波三级分解提取低频子图像,对低频子图像应用PLS提取掌纹特征,然后将样本投影到提取的特征上作为特征向量进行分类识别.应用PolyU掌纹图像库进行实验分析,实验结果表明:与主元分析(PCA)、二维主元分析(2DPCA)和独立主元分析(ICA)相比,该方法的识别率得到了很大的提高,大大减小了误识率和拒识率,验证了该方法的有效性.

| Abstract: | A palmprint recognition method based on wavelet transformation and partial least square(PLS)is proposed in order to reduce the computational complex and consider class information when the features of images are extracted.A palmprint image was decomposed to low frequency sub-images by the three-level wavelet transform so as to decrease the computation complexity.Then a low frequency sub-image was selected for feature extraction by PLS.The original palmprint image was mapped into feature space as feature vec... |
