Abstract: For the defects that vein image quality assessment criterion was mainly relied on subjective judgment currently, a vein image quality assessment algorithm based on feature discrimination was proposed. Firstly, a quality assessment model was proposed based on vein image features, then model parameters were fixed according to the discrimination of training samples feature, and finally high quality features of acquired vein images can be extracted based on model optimization. Experiments show that the extracted features have good dispersion in different classes, and the recognition effect is improved.
