While many caricatures are 2D images, this paper presents an\nalgorithm for creating expressive 3D caricatures from 2D caricature images with\na minimum of user interaction. The key idea of our approach is to introduce an\nintrinsic deformation representation that has a capacity of extrapolation\nenabling us to create a deformation space from standard face dataset, which\nmaintains face constraints and meanwhile is sufficiently large for producing\nexaggerated face models. Built upon the proposed deformation representation, an\noptimization model is formulated to find the 3D caricature that captures the\nstyle of the 2D caricature image automatically. The experiments show that our\napproach has better capability in expressing caricatures than those fitting\napproaches directly using classical parametric face models such as 3DMM and\nFaceWareHouse. Moreover, our approach is based on standard face datasets and\navoids constructing complicated 3D caricature training set, which provides\ngreat flexibility in real applications.","url_abs":"http://arxiv.org/abs/1803.06802v3","url_pdf":"http://arxiv.org/pdf/1803.06802v3.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"alive-caricature-from-2d-to-3d","repo_url":"https://github.com/QianyiWu/Caricature-Data","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"caricature","task_name":"Caricature"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":"https://app.syntology.ai/?focus=1803.06802","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
