Publication number: 20240127729Abstract: Embodiments of this application provide an electronic device display method and an electronic device. The electronic device includes a foldable body, an outer screen, and an inner screen, and the method includes: when the foldable body is in a folded state, detecting whether a protective cover approaches the outer screen and reaches a preset position with respect to the outer screen; if the protective cover reaches the preset position with respect to the outer screen, when the preset condition is met, determining whether the foldable body is switched to a non-folded state; and if the foldable body is switched to the non-folded state, controlling the electronic device to be in a screen non-locked state. That the preset condition is met includes at least being within a preset time after the protective cover reaches the preset position.Type: ApplicationFiled: December 20, 2022Publication date: April 18, 2024Applicant: Honor Device Co., Ltd.Inventors: Shilei WANG, Hepu CAO, Peng WANG

Patent number: 11887311Abstract: Embodiments of this disclosure include a method and an apparatus for segmenting a medical image. The method may include obtaining a slice pair comprising two slices and performing feature extraction on each slice in the slice pair, to obtain high-level feature information and low-level feature information of the each slice in the slice pair. The method may further include segmenting a target object in the each slice according to the low-level feature information and the high-level feature information of the slice, to obtain an initial segmentation result of the each slice and fusing the low-level feature information and the high-level feature information of the slices to obtain a fused feature information. The method may further include determining correlation information between the slices according to the fused feature information and generating a segmentation result of the slice pair based on the correlation information and the initial segmentation results of the slices.Type: GrantFiled: July 29, 2021Date of Patent: January 30, 2024Assignee: Tencent Technology (Shenzhen) Company LimitedInventors: Shilei Cao, Renzhen Wang, Kai Ma, Yefeng Zheng

Patent number: 11854205Abstract: This application relates to a medical image segmentation method, a computer device, and a storage medium. The method includes: obtaining medical image data; obtaining a target object and weakly supervised annotation information of the target object in the medical image data; determining a pseudo segmentation mask for the target object in the medical image data according to the weakly supervised annotation information; and performing mapping on the medical image data by using a preset mapping model based on the pseudo segmentation mask, to obtain a target segmentation result for the target object. Because the medical image data is segmented based on the weakly supervised annotation information, there is no need to annotate information by using much labor during training of the preset mapping model, thereby saving labor costs. The preset mapping model is a model used for mapping the medical image data based on the pseudo segmentation mask.Type: GrantFiled: April 13, 2021Date of Patent: December 26, 2023Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Shilei Cao, Kai Ma, Yefeng Zheng
