Publication number: 20240161245Abstract: In an image optimization method, an image generation network, a to-be-optimized image, and a plurality of preset image features are obtained. A target feature is selected from the plurality of preset image features based on (i) the target feature and the to-be-optimized image and (ii) a preset similarity condition. The target feature and an initial offset parameter are input to the image generation network. The initial offset parameter is adjusted according to a difference between an output of the image generation network and the to-be-optimized image, to obtain a target offset parameter. The target feature and the target offset parameter are input to the image generation network, to generate an optimized image. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.Type: ApplicationFiled: January 24, 2024Publication date: May 16, 2024Applicant: Tencent Technology (Shenzhen) Company LimitedInventors: Chuming LIN, Yanbo WANG, Donghao LUO, Ying TAI, Zhizhong ZHANG, Yuan XIE, Chengjie WANG

Publication number: 20240141537Abstract: The present disclosure provides a superhydrophobic and self-cleaning anticoagulant composite coating material and a preparation method and use thereof, and relates to the technical field of biomedical materials. In the coating material provided by the present disclosure, a titanium dioxide nanotube-based structure increases microscopic roughness of a surface of a titanium-based metal substrate, and a hydrophobic modification layer reduces surface energy of the material. The rough structure and the hydrophobic modification layer have a synergistic effect to construct a superhydrophobic surface, making the surface of the material have self-cleaning characteristics and low adhesion. Air can be retained on the surface of the material to form an air layer, thereby reducing the contact area between the material and bacteria and platelets in the blood, and inhibiting adhesion of the bacteria, platelets, and plasma proteins to the material.Type: ApplicationFiled: November 8, 2022Publication date: May 2, 2024Applicant: Anhui Medical UniversityInventors: Shunli ZHENG, Qin RAO, Ling WENG, Jinshuang ZHANG, Donghao LIU, Quanli LI, Ying CAO, Jialong CHEN, Xiangyang LI, Hua QIU, Shengzhuo ZHANG, Daojun SHEN
