Publication number: 20200005021Abstract: A face detection device has a classifier configured to determine, while scanning an image with a search window, whether a partial image in the search window is a face image with use of an image feature based on a difference in luminance between local regions in the partial image. The face detection device determines whether the partial image in the search window is a low-luminance image, and performs determination by the classifier with use of a changed partial image obtained by changing a luminance of a pixel in a predetermined position in the partial image instead of the partial image when determined that the partial image is a low-luminance image.Type: ApplicationFiled: November 28, 2017Publication date: January 2, 2020Applicant: Omron CorporationInventors: Masahiro Akagi, Hiroaki Terai, Shinji Endo
