Patent number: 11967115Abstract: The present disclosure discloses a color matching evaluation method combining similarity measure and visual perception. The method includes: firstly, constructing an image database with rich color information; extracting main colors from an acquired image using an improved clustering method for color matching; generating a corresponding palette using an intelligent color matching recommendation system, and evaluating a palette similarity using a minimum color difference model; then, recoloring the corresponding image using the generated palette through an image recoloring technology to obtain a recolored image, and calculating a structural similarity between the source image and the recolored image; performing feature level adaptive weighted fusion on the palette similarity and the structural similarity, and performing an eye movement tracking experiment on the source image and the recolored image to obtain visual perception data of the images.Type: GrantFiled: December 28, 2023Date of Patent: April 23, 2024Assignee: WUHAN TEXTILE UNIVERSITYInventors: Li Yuan, Jiaqi Xiong, Jiachen Shen, Shengjie Yang, Xinru Wu

Patent number: 11899929Abstract: A method for customizing a key of a foldable device, a device, and a storage medium are provided. When the foldable device is in a folded state, a touchscreen of the foldable device is divided into three regions: a primary screen, a back screen, and a secondary screen. According to the method for customizing a key, the foldable device receives a first user operation used to indicate the foldable device to add a custom key on the back screen or the secondary screen, and then obtains a physical state of the foldable device. If the foldable device is in a folded state, the custom key is added on the back screen or the secondary screen based on the first user operation.Type: GrantFiled: December 2, 2020Date of Patent: February 13, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Qingfeng Xue, Jiachen Yang

Publication number: 20230067322Abstract: A gesture recognition method and a related apparatus are provided, to obtain a first point cloud data set by filtering an original point cloud data set collected by a radar apparatus. The first point cloud data set includes a plurality of frames of first point cloud subsets, the first point cloud subset includes a first cluster center, the first cluster center is a cluster center of a plurality of pieces of point cloud data in the first point cloud subset, a maximum horizontal distance between any two first cluster centers meets a first preset condition, and duration of the first point cloud data set meets the first preset condition. Point cloud data whose motion track does not match gesture motion can be effectively filtered out. Gesture recognition is performed by using the first point cloud data set obtained by filtering.Type: ApplicationFiled: October 28, 2022Publication date: March 2, 2023Inventors: Genming Ding, Yanong He, Danni Kuang, Jingwei Qu, Feng Liu, Jiachen Yang, Erli Wang
