| titleOfInvention | Palm vein classified index construction method based on direction character |
| abstract | The invention discloses a kind of palm vein classified index construction methods based on direction character, it uses Gaussian_iRadon（G‑iR）The direction character matrix of conversion extraction palm arteries and veins image, obtain image principal direction, classified index is built with this image principal direction, a kind of palm vein classified index construction method based on direction character provided by the invention, extraction vena metacarpea image direction characteristic information is converted using Gaussian Radon, and it is analyzed with statistic law high, in, the corresponding direction character matrix of image under low three kinds of resolution ratio, and then obtain simple and effective classified index structure, it can enhance to slapping the deformation error of arteries and veins and the robustness of noise, have effectively achieved the uniformity of sample distribution in each word bank, greatly reduce retrieval time. |
