A Contrast Enhancement Method of Infrared Finger Vein Image Based on Fuzzy Technique

This paper presents a contrast enhancement method based on fuzzy technique to infrared finger vein image for identification recognition. In order to solve the low contrast, blurring, speckle noise, the fuzzy set theory proposed is used for the captured infrared image enhancement. After the gray enhancement, the vein pattern feature extract and recognition are employed. The finger vein recognition accuracy results of 2070 vein images show the enhance efficient of the conducted fuzzy algorithm.
