Patent number: 11948233Abstract: An image display method includes drawing a first graph in a trusted execution environment (TEE). The method also includes displaying the first graph on a first layer in a display screen. The method further includes drawing a second graph in a rich execution environment (REE). The method additionally includes displaying the second graph on a second layer in the display screen. The first layer is located above the second layer. The first graph includes a transparent area and a non-transparent area. The non-transparent area includes content drawn in the TEE. A display area that is on the second graph and that corresponds to the transparent area includes content drawn in the REE. When the first layer and the second layer are overlapped for displaying, the transparent area does not shield the content drawn in the REE.Type: GrantFiled: April 22, 2022Date of Patent: April 2, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Jingchao Zhang, Yan Yan, Lian Wang

Publication number: 20240105193Abstract: This application provides picture or audio encoding and decoding methods and apparatuses, and relates to the field of artificial intelligence (AI)—based picture or audio encoding and decoding technologies, and specifically, to the field of neural network-based picture feature map or audio feature variable encoding and decoding technologies. The encoding method includes: obtaining a to-be-encoded target, where the to-be-encoded target includes a plurality of feature elements, and the plurality of feature elements include a first feature element. The method further includes: obtaining a probability estimation result of the first feature element; determining, based on the probability estimation result of the first feature element, whether to perform entropy encoding on the first feature element; and performing entropy encoding on the first feature element only when it is determined that entropy encoding needs to be performed on the first feature element.Type: ApplicationFiled: December 1, 2023Publication date: March 28, 2024Inventors: Jue Mao, Yin Zhao, Ning Yan, Haitao Yang, Lian Zhang, Jing Wang, Yibo Shi
