CaricatureShop: Personalized and Photorealistic Caricature Sketching [article]

Xiaoguang Han, Kangcheng Hou, Dong Du, Yuda Qiu, Yizhou Yu, Kun Zhou, Shuguang Cui
2018 arXiv   pre-print
In this paper, we propose the first sketching system for interactively personalized and photorealistic face caricaturing.  ...  Our system firstly performs exaggeration on the recovered 3D face model according to the edited sketches, which is conducted by assigning the laplacian of each vertex a scaling factor.  ...  In Section 6, we will also describe an interactive refinement module for mouth region filling and sketch-based ear editing.  ...

Two-Stage Sketch Colorization with Color Parsing

Hui Ren, Jia Li, Nan Gao
2019 IEEE Access  
As for evaluation metrics, we propose a color-coded local binary pattern (CCLBP) score based on color distances from the first-order 8 pixels to the central pixel, to measure the degrees of color blurring  ...  Additionally, we use the intermediate feature of sampling points as constraint and achieve the color reconstruction using Laplacian mesh editing as a special second stage.  ...  Our model with the grayscale map performs better than our model with the pixels and the model with the Laplacian mesh editing in autonomous coloring.  ...

2008 Engineering with Computers  
We will demonstrate mesh generation for example problems along with methods for verifying the quality of the meshes generated.  ...  The latter process often involves segmentation, mesh generation, and numerical simulations.  ...  Sets of faces can be interactively added or deleted from the model by the user. This allows models to more quickly be patched and made ready for the tetrahedralization.  ...
