Publication number: 20200143544Abstract: An image recognition device sets an overall observation region which surrounds a whole body of an object and partial observation regions which surround characteristic parts of the object respectively to locations in an image which are estimated to include captured images of the object. The device clips images in the overall observation region and the partial observation regions, and calculates similarity degrees between them and previously learned images on the basis of a combination of two image feature amounts. The device calculates an optimum ratio in combining the HOG feature amount and the color distribution feature amount individually for the regions. This ratio is determined by setting a weight parameter ?i for setting a weight used for combining the HOG feature amount and the color distribution feature amount to be included in a state vector and subjecting the result to complete search by a particle filter.Type: ApplicationFiled: March 30, 2017Publication date: May 7, 2020Applicants: EQUOS RESEARCH CO., LTD., KYUSHU INSTITUTE OF TECHNOLOGYInventors: Hideo YAMADA, Kazuhiro KUNO, Shuichi ENOKIDA, Tatsuya HASHIMOTO
