- Abstract:
-
According to the features of finger vein images, a new evaluation method of image quality was proposed in this paper. On the basis of the analysis of the Human Visual System (HVS) function, the image properties such as effective region, image contrast, position offset, fuzzy degree, and information entropy were utilized as the parameters of finger vein image quality assessment. Then an evaluation function of vein image quality was obtained through comprehensive analysis and weighting of those parameters. The experimental results show that the objective evaluation value is in accordance with the subjective evaluation value.
