简介:编码基于的方法的一篇小说说出同样本地的二进制取向代码(LBOCode)因为palmprint识别被建议。palmprint图象第一与Gabor过滤器的一个银行被卷,然后取向信息与一条winner-take-all规则被达到。随后,产生取向印射数组被一致本地二进制模式操作。因此,LBOCode图象被完成它在象素水平包含palmprint取向信息。进一步,我们把LBOCode图象划分成几相等尺寸并且nonoverlapping区域,和摘录从每个区域的统计代码直方图独立地,它在地区性的水平造对palmprint的全球描述。在匹配舞台,在二palmprints之间的匹配的分数被精明的二张空间提高的直方图的不同完成,它带计算简洁的利益。试验性的结果证明建议方法与几个最先进的方法的相比完成更有希望的识别性能。
