Abstract
We examined the evaluation method by image processing of the fingertip blood vessels. Using the clinical Figures of the nailfold capillary, we tried to clear characteristics of the fingertip capillaries by the feature point extraction. Also it has been realized to simplify the process by performing the numerical values for the state of the fingertip blood vessel from the clinical picture, to prepare a program for calculating the parameters automatically. Further, it could be useful to evaluate the performance of supplementation measuring the parameters of the microcapillary shape by image processing.
