Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we evaluate of the quality of a baseball pitching motion in which the batters feel difficulty in hitting a ball. The proposed scheme to evaluate the pitch difficulty is based on a model using OpenPose, Motion History Images, and a multiple-instance Support Vector Machine. These techniques allow us to analyze video data effectively quantitatively, and objectively. Our results correlate with empirical knowledges of domain experts. For example, the results say that the pitch difficulty increases when the dominant hand as well as the ball is invisible. It is worthy that the proposed scheme can be generalized and can be applied not only baseball but also various sports and motions.
