The segmentation algorithm for hand vein images based on improved Niback algorithm

摘要：

　　The local dynamic threshold segmentation algorithm,Niblack algorithm,is more suitable for hand vein images segmentation by comparing the common-used algorithms.But the traditional Niblack algorithm has weakness,so this paper proposed an improved Niblack algorithm in which the coefficient k is adaptive estimated.The results show that the improved algorithm can better segment the hand vein outlines,preserve the vein original characteristics,and meet the needs of the follow-up feature extraction and recognition.
