Firstly, two representations of the image's granularity to simulate the visual effects of different granularities are presented, and acquire face images of different granularities accordingly. Then the cost-sensitive three-way decision model is introduced to decision-making to get the decision with the minimum cost. Finally, the experiment on the PIE and ORL data prove that multi-granularity cost-sensitive three-way decision is effective to simulate the decison process of human beings.
