SUMMARY:AgileAvatar: Stylized 3D Avatar Creation via Cascaded Domain Bridg
 ing
DESCRIPTION:Technical Papers\n\nAgileAvatar: Stylized 3D Avatar Creation v
 ia Cascaded Domain Bridging\n\nSang, Zhi, Song, Liu, Lai...\n\nStylized 3D
  avatars have become increasingly prominent in our modern life. Creating t
 hese avatars manually usually involves laborious selection and adjustment 
 of continuous and discrete parameters and is time-consuming for average us
 ers. Self-supervised approaches to automatically create 3D avatars from us
 er selfies promise high quality with little annotation cost but fall short
  in application to stylized avatars due to a large style domain gap. We pr
 opose a novel self-supervised learning framework to create high-quality st
 ylized 3D avatars with a mix of continuous and discrete parameters. Our ca
 scaded domain bridging framework first leverages a modified portrait styli
 zation approach to translate input selfies into stylized avatar renderings
  as the targets for desired 3D avatars. Next, we find the best parameters 
 of the avatars to match the stylized avatar renderings through a different
 iable imitator we train to mimic the avatar graphics engine. To ensure we 
 can effectively optimize the discrete parameters, we adopt a cascaded rela
 xation-and-search pipeline. We use a human preference study to evaluate ho
 w well our method preserves user identity compared to previous work as wel
 l as manual creation. Our results achieve much higher preference scores th
 an previous work and close to those of manual creation. We also provide an
  ablation study to justify the design choices in our pipeline.\n\nRegistra
