| Abstract: | This article discusses in detail the realization DSP-based palm print positioning algorithm. The morphological method is used to extract the key point of the palmprint images, extracted the key point, the ＂newprinciple＂ algorithm is adopted to rotate the image, thus achieving high accuracy and efficiency. The method proposed in this paper is simple and efficient in operation, but it also has certain limitations and defects. |
