Robust Noise Modeling for Spike Camera via Time-Interval Quantification and Spike-DSLR Multimodal Dataset in Low-Light Imaging

AAAI 2026technical

The inherent differences between spike cameras and traditional frame-based cameras lead to more complex and diverse noise characteristics, particularly under extremely low-light conditions. Existing noise modeling approaches for spike camera predominantly rely on inter-spike intervals (ISI) for nois

Structured Discrete Graph Generation Model for Fragmented Image Recovery

IJCAI 2026

Fragmented image recovery is of significant importance in computer vision, such as cultural relic and artwork restoration, archival document recovery, and digital forensics. The goal is to recover the original image topology from an unordered set of fragments and spatially align and stitch them toge

Boosting Adversarial Transferability via Negative Hessian Trace Regularization

ICCV 2025poster

Transferability makes the black-box attacks to be practical. Recent studies demonstrate that adversarial examples situated at the flat maxima on the loss landscape tend to exhibit higher transferability and propose effective strategies to optimize adversarial examples to converge toward that region.…

EdgeSpotter: Multi-Scale Dense Text Spotting for Industrial Panel Monitoring

IROS 2025

Text spotting for industrial panels is a key task for intelligent monitoring. However, achieving efficient and accurate text spotting for complex industrial panels remains challenging due to issues such as cross-scale localization and ambiguous boundaries in dense text regions. Moreover, most existi

Enhancing Transferability of Audio Adversarial Example for Both Frequency- and Time-domain

IJCAI 2025

Audio adversarial examples impose acoustically imperceptible perturbations to clean audio examples, fooling classification models into producing incorrect results. Transferability is a critical property of audio adversarial examples, making black-box attacks applicable in practice and attracting inc

ZVEFusion: Zero-Shot Visual Enhancement Fusion for Infrared and Visible Images in Low Light

ICASSP 2025accepted

Infrared and visible image fusion (IVIF) aims to generate fused images with prominent targets and rich scene information. However, in low-light conditions, visible images lose accurate texture and color, reducing their ability to provide detailed scene information for fusion. Existing IVIF methods o…

Zero-Shot Noise2Mean: Gap Minimization for Efficient Denoising from a Single Noisy Image

AAAI 2025technical

Acquiring pairwise noisy-clean training data is challenging. Consequently, some self-supervised denoising methods utilize noisy image pairs as both input and target for network training. However, a major issue with these methods is the gap between the clean images of the input and target. In this pa…

DP-Font: Chinese Calligraphy Font Generation Using Diffusion Model and Physical Information Neural Network

IJCAI 2024poster

As a typical visual art form, Chinese calligraphy has a long history and aesthetic value. However, current methods for generating Chinese fonts still struggle with complex character shapes and lack personalized writing styles. To address these issues, we propose a font generation method for Chinese…

Reparameterized Importance Sampling for Robust Variational Bayesian Neural Networks

ICML 2024poster

Mean-field variational inference (MFVI) methods provide computationally cheap approximations to the posterior of Bayesian Neural Networks (BNNs) when compared to alternatives like MCMC. However, applying MFVI to BNNs encounters limitations due to the Monte Carlo sampling problem. This problem stems…

ZERO-IG: Zero-Shot Illumination-Guided Joint Denoising and Adaptive Enhancement for Low-Light Images

CVPR 2024poster

This paper presents a novel zero-shot method for jointly denoising and enhancing real-word low-light images. The proposed method is independent of training data and noise distribution. Guided by illumination we integrate denoising and enhancing processes seamlessly enabling end-to-end training. Pair…
