propose a method for extracting features by using gaze positions acquired from people to classify gender of images of people. It has been well known that gaze improves performance of classification for various tasks. We newly tackle to develop a method of utilizing gaze for gender classification. Our method acquires changes of gaze positions looked by subjects when classifying gender of images of people. We integrate changes of gaze positions between subjects and generate a gaze map for giving weights when extracting features. We observed that subjects look at head regions when classifying gender. Our experiments show that our method improves performance of gender classification by using a gaze map for feature extraction. We also demonstrated that our method is superior to metric learning or deep learning techniques when the number of training samples is small.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータビジョンとイメージメディア(CVIM)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2016-08-29","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"39","bibliographicVolumeNumber":"2016-CVIM-203"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
