Source-Prior-Driven Selective Adaptation for Efficient Diffusion Model Finetuning
Yi Xiong, Yuan-Yuan Cheng, Xiao-Ming Fu
Fine-tuning large diffusion models for new domains or styles involves a trade-off: improving target-specific generation often degrades the pretrained model's broad generative capab…
BRepMAE: Self-Supervised Masked BRep Autoencoders for Machining Feature Recognition
Can Yao, Kang Wu, Zuheng Zheng +2
We propose a masked self-supervised learning framework, called BRepMAE, for automatically extracting a valuable representation of the input computer-aided design (CAD) model to rec…
Efficient Computation of Integer-constrained Cones for Conformal Parameterizations
Wei Du, Qing Fang, Ligang Liu +1
We propose an efficient method to compute a small set of integer-constrained cone singularities, which induce a rotationally seamless conformal parameterization with low distortion…
Polynomial 2D Green Coordinates for High-order Cages
Shibo Liu, Ligang Liu, Xiao-Ming Fu
We propose conformal polynomial coordinates for 2D closed high-order cages, which consist of polynomial curves of any order. The coordinates enable the transformation of the input…
Polynomial 2D Biharmonic Coordinates for High-order Cages
Shibo Liu, Ligang Liu, Xiao-Ming Fu
We derive closed-form expressions of biharmonic coordinates for 2D high-order cages, enabling the transformation of the input polynomial curves into polynomial curves of any order.…
