Deep MSFOP: Multiple Spectral filter Operators Preservation in Deep Functional Maps for Unsupervised Shape Matching

no code implementations6 Feb 2024 Feifan Luo, Qingsong Li, Ling Hu, Xinru Liu, Haojun Xu, Haibo Wang, Ting Li, Shengjun Liu

We propose a novel constraint called Multiple Spectral filter Operators Preservation (MSFOR) to compute functional maps and based on it, develop an efficient deep functional map architecture called Deep MSFOP for shape matching.

Efficient Deformable Shape Correspondence via Multiscale Spectral Manifold Wavelets Preservation

no code implementations CVPR 2021 Ling Hu, Qinsong Li, Shengjun Liu, Xinru Liu

The functional map framework has proven to be extremely effective for representing dense correspondences between deformable shapes.

Memory-Efficient Modeling and Slicing of Large-Scale Adaptive Lattice Structures

no code implementations13 Jan 2021 Shengjun Liu, Tao Liu, Qiang Zou, Weiming Wang, Eugeni L. Doubrovski, Charlie C. L. Wang

The presented methods have been validated by a series of case studies with large number (up to 100M) of struts to demonstrate its applicability to large-scale lattice structures.

Visual Attack and Defense on Text

no code implementations7 Aug 2020 Shengjun Liu, Ningkang Jiang, Yuanbin Wu

Modifying characters of a piece of text to their visual similar ones often ap-pear in spam in order to fool inspection systems and other conditions, which we regard as a kind of adversarial attack to neural models.

Learning to predict crisp boundaries

1 code implementation ECCV 2018 Ruoxi Deng, Chunhua Shen, Shengjun Liu, Huibing Wang, Xinru Liu

Recent methods for boundary or edge detection built on Deep Convolutional Neural Networks (CNNs) typically suffer from the issue of predicted edges being thick and need post-processing to obtain crisp boundaries.
