Abstract :
This paper proposes an image enhancement algorithm based on fuzzy theory. The average of all adjacent points is as enhancement threshold and affiliation of each point is obtained by counting the average. Then, enhancement images are obtained with inverse transformation. Experiments have proved that contrast of vein and background is enhanced and effect of image segmentation and extraction is improved with the method. This method is a very simple and practical vein image enhancement algorithm.
