We propose a self-adaptive canonical points upsampling strategy to achieve high-resolution hand geometry representation. This is followed by a self-adaptive deformation that deforms the hand from the canonical space to the target pose, adapting to the dynamic changing of canonical points which, in contrast to the common practice of subdividing the MANO model, offers greater flexibility and results in improved geometry fitting. To model texture, we disentangle the appearance color into the intrinsic albedo and pose-aware shading, which are learned through a Context-Attention module. Moreover, our approach allows the geometric and the appearance models to be trained simultaneously in an end-to-end manner. We demonstrate that our method is capable of producing animatable, photorealistic and relightable hand reconstructions using multiple datasets, including monocular videos captured with handheld smartphones and large-scale multi-view videos featuring various hand poses. We also demonstrate that our approach achieves real-time rendering speeds while simultaneously maintaining superior performance compared to existing state-of-the-art methods.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Authors<\/h2>\n\n\n\n<figure class=\"wp-block-gallery aligncenter has-nested-images columns-4 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large wp-duotone-grayscale\"><img data-recalc-dims=\"1\" fetchpriority=\"high\" decoding=\"async\" width=\"736\" height=\"736\" data-id=\"294\" src=\"https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2021\/11\/JiangZheheng-736x736-1.jpg?resize=736%2C736&#038;ssl=1\" alt=\"\" class=\"wp-image-294\" srcset=\"https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2021\/11\/JiangZheheng-736x736-1.jpg?w=736 736w, https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2021\/11\/JiangZheheng-736x736-1.jpg?resize=300%2C300 300w, https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2021\/11\/JiangZheheng-736x736-1.jpg?resize=150%2C150 150w\" sizes=\"(max-width: 736px) 100vw, 736px\" \/><figcaption class=\"wp-element-caption\">Dr Zheheng Jiang<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large wp-duotone-grayscale\"><img data-recalc-dims=\"1\" decoding=\"async\" width=\"736\" height=\"736\" data-id=\"2269\" src=\"https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2023\/09\/RahmaniHossein2-736x736-1.png?resize=736%2C736&#038;ssl=1\" alt=\"\" class=\"wp-image-2269\" srcset=\"https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2023\/09\/RahmaniHossein2-736x736-1.png?w=736 736w, https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2023\/09\/RahmaniHossein2-736x736-1.png?resize=300%2C300 300w, https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2023\/09\/RahmaniHossein2-736x736-1.png?resize=150%2C150 150w\" sizes=\"(max-width: 736px) 100vw, 736px\" \/><figcaption class=\"wp-element-caption\">Dr Hossein Rahmani<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large wp-duotone-grayscale\"><img data-recalc-dims=\"1\" decoding=\"async\" width=\"736\" height=\"736\" data-id=\"299\" src=\"https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2021\/11\/BlackSue-736x736-1.jpg?resize=736%2C736&#038;ssl=1\" alt=\"\" class=\"wp-image-299\" srcset=\"https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2021\/11\/BlackSue-736x736-1.jpg?w=736 736w, https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2021\/11\/BlackSue-736x736-1.jpg?resize=300%2C300 300w, https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2021\/11\/BlackSue-736x736-1.jpg?resize=150%2C150 150w\" sizes=\"(max-width: 736px) 100vw, 736px\" \/><figcaption class=\"wp-element-caption\">Prof Lady Sue Black<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large wp-duotone-grayscale\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"736\" height=\"736\" data-id=\"2268\" src=\"https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2023\/09\/WilliamsBryan2-736x736-1.png?resize=736%2C736&#038;ssl=1\" alt=\"\" class=\"wp-image-2268\" srcset=\"https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2023\/09\/WilliamsBryan2-736x736-1.png?w=736 736w, https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2023\/09\/WilliamsBryan2-736x736-1.png?resize=300%2C300 300w, https:\/\/i0.wp.com\/wp.lancs.ac.uk\/icvl\/files\/2023\/09\/WilliamsBryan2-736x736-1.png?resize=150%2C150 150w\" sizes=\"(max-width: 736px) 100vw, 736px\" \/><figcaption class=\"wp-element-caption\">Dr Bryan M.
