| 摘 要： | 利用正交Legendre矩实现对虹膜图像的特征提取。根据该算法得到的每一位特征向量都包含了图像中各像素点的灰度信息和位置信息。与基于矩的其他特征提取算法相比，它不仅有良好的鲁棒性，而且还保留了图像的二维信息。实验结果充分表明, 该算法是合理有效的。

| Abstract: | Orthogonal Legendre moments were utilized to achieve characteristics extract from an iris image. Each feature vector, based on this algorithm, included the grey value and coordinate of each pixel in the image. Compared with other algorithms based on moments, this algorithm not only favors the robustness, but also preserves the 2-D information of the image. The experiment results indicate that the algorithm has good effectiveness and rationality. |
