Extracting Palm Vein Patterns Based on Low-Cost Devices
Abstract:
Abstract. In order to figure out the low-cost imaging apparatus’ problems, such as the low image contrast, the indistinct vein characteristics, which are affected by the photoelectric noise during the collection process. In this paper, the vein imaging principle is discussed, and a low-cost collection device is designed, at the same time a two-dimensional multi-directional Gaussian filter is constructed to achieve the enhancement of low quality palm vein image, and the Local Dynamic Threshold Segmentation Method (Niblack) is adopted to extract vein characteristics. The results show that this method is able to extract distinct vein characteristics, and also can provide reliable characteristics basis for palm vein recognition system.
