Image Retrieval Using Shape Recognition
◎Natsuda Kaothanthong・Yoshiki Ota・Jinhee Chun・Takeshi Tokuyama（東北大）
The time complexity of using the geometric pattern matching to retrieved similar images from the database size N is O(N p(n)) where p(n) is the time complexity for a geometric pattern matching. Shape invariant is used to speed up the retrieval time by reducing a similarity computation into a vector space. In this research, we present the problems of using the shape invariant to retrieve similar images. The two-stage image retrieval is proposed to solve the problem when using the shape invariant.
