An Improved Quick Thinning Algorithm for Fingerprint Image

ZHANG Xian-quan,TANG Ying,GUO Ming-ming(Department of Computer Science,Guangxi Normal University,Guilin,Guangxi,541004,China)  
The characteristics of eight-neighbor pixels were studied to solve the problem of double pixels width in the quick thinning algorithm.By computing the sum of eight-neighbor pixel values and researching the relationship between the adjacent eight-neighbor pixels,an improved quick thinning algorithm is proposed.The result in the improved algorithm becomes one pixel width.The experimental results show that the improved algorithm runs quick and efficient.
