LoopGaussian: Creating 3D Cinemagraph with Multi-view Images via Eulerian Motion Field

no code implementations13 Apr 2024 Jiyang Li, Lechao Cheng, Zhangye Wang, Tingting Mu, Jingxuan He

In this paper, inspired by significant progress in the field of novel view synthesis (NVS) achieved by 3D Gaussian Splatting (3D-GS), we propose LoopGaussian to elevate cinemagraph from 2D image space to 3D space using 3D Gaussian modeling.

Progressive Feature Self-reinforcement for Weakly Supervised Semantic Segmentation

1 code implementation14 Dec 2023 Jingxuan He, Lechao Cheng, Chaowei Fang, Zunlei Feng, Tingting Mu, Mingli Song

Building upon this, we introduce a complementary self-enhancement method that constrains the semantic consistency between these confident regions and an augmented image with the same class labels.

Large Language Models for Code: Security Hardening and Adversarial Testing

1 code implementation10 Feb 2023 Jingxuan He, Martin Vechev

The task is parametric and takes as input a binary property to guide the LM to generate secure or unsafe code, while preserving the LM's capability of generating functionally correct code.

On Distribution Shift in Learning-based Bug Detectors

1 code implementation21 Apr 2022 Jingxuan He, Luca Beurer-Kellner, Martin Vechev

To address this key challenge, we propose to train a bug detector in two phases, first on a synthetic bug distribution to adapt the model to the bug detection domain, and then on a real bug distribution to drive the model towards the real distribution.
