Mining Instance-Centric Vision-Language Contexts for Human-Object Interaction Detection

CVPR 2026

Human-Object Interaction (HOI) detection aims to localize human-object pairs and classify their interactions from a single image, a task that demands strong visual understanding and nuanced contextual reasoning. Recent approaches have leveraged Vision-Language Models (VLMs) to introduce semantic pri

ParallelBench: Understanding the Trade-offs of Parallel Decoding in Diffusion LLMs

ICLR 2026poster

While most autoregressive LLMs are constrained to one-by-one decoding, diffusion LLMs (dLLMs) have attracted growing interest for their potential to dramatically accelerate inference through parallel decoding. Despite this promise, the conditional independence assumption in dLLMs causes parallel dec…

TM-BSN: Triangular-Masked Blind-Spot Network for Real-World Self-Supervised Image Denoising

CVPR 2026

Blind-spot networks (BSNs) enable self-supervised image denoising by preventing access to the target pixel, allowing clean signal estimation without ground-truth supervision. However, this approach assumes pixel-wise noise independence, which is violated in real-world sRGB images due to spatially co

Time Without Time: Pseudo-Temporal Representation for Space-Time Super-Resolution

CVPR 2026

Space-time video super-resolution (STVSR) is a task aimed at simultaneously upsampling a video in both spatial and temporal dimensions. Previous studies on STVSR have primarily focused on task-specific architectures and modeling paradigms, while effective pretraining strategies remain underexplored.

Efficient Attention-Sharing Information Distillation Transformer for Lightweight Single Image Super-Resolution

AAAI 2025technical

Transformer-based Super-Resolution (SR) methods have demonstrated superior performance compared to convolutional neural network (CNN)-based SR approaches due to their capability to capture long-range dependencies. However, their high computational complexity necessitates the development of lightweig…

Lightweight and Fast Real-time Image Enhancement via Decomposition of the Spatial-aware Lookup Tables

ICCV 2025poster

The image enhancement methods based on 3D lookup tables (3D LUTs) efficiently reduce both model size and runtime by interpolating pre-calculated values at the vertices. However, the 3D LUT methods have a limitation due to their lack of spatial information, as they convert color values on a point-by-…

RefPose: Leveraging Reference Geometric Correspondences for Accurate 6D Pose Estimation of Unseen Objects

CVPR 2025poster

Estimating the 6D pose of unseen objects from monocular RGB images remains a challenging problem, especially due to the lack of prior object-specific knowledge. To tackle this issue, we propose RefPose, an innovative approach to object pose estimation that leverages a reference image and geometric c…

Semantic Watermarking Reinvented: Enhancing Robustness and Generation Quality with Fourier Integrity

ICCV 2025poster

Semantic watermarking techniques for latent diffusion models (LDMs) are robust against regeneration attacks, but often suffer from detection performance degradation due to the loss of frequency integrity. To tackle this problem, we propose a novel embedding method called Hermitian Symmetric Fourier…

State-offset Tuning: State-based Parameter-Efficient Fine-Tuning for State Space Models

ACL 2025short

State Space Models (SSMs) have emerged as efficient alternatives to Transformers, mitigating their quadratic computational cost. However, the application of Parameter-Efficient Fine-Tuning (PEFT) methods to SSMs remains largely unexplored. In particular, prompt-based methods like Prompt Tuning and P…

Panel-Specific Degradation Representation for Raw Under-Display Camera Image Restoration

ECCV 2024poster

"Under-display camera (UDC) image restoration aims to restore images distorted by the OLED display panel covering the frontal camera on a smartphone. Previous deep learning-based UDC restoration methods focused on restoring the image within the RGB domain with the collection of real or synthetic RGB…

Perception-Oriented Single Image Super-Resolution Using Optimal Objective Estimation

CVPR 2023poster

Single-image super-resolution (SISR) networks trained with perceptual and adversarial losses provide high-contrast outputs compared to those of networks trained with distortion-oriented losses, such as L1 or L2. However, it has been shown that using a single perceptual loss is insufficient for accur…

Self-supervised Image Denoising with Downsampled Invariance Loss and Conditional Blind-Spot Network

ICCV 2023poster

There have been many image denoisers using deep neural networks, which outperform conventional model-based methods by large margins. Recently, self-supervised methods have attracted attention because constructing a large real noise dataset for supervised training is an enormous burden. The most repr…

Deep Hash Distillation for Image Retrieval

ECCV 2022poster

"In hash-based image retrieval systems, degraded or transformed inputs usually generate different codes from the original, deteriorating the retrieval accuracy. To mitigate this issue, data augmentation can be applied during training. However, even if augmented samples of an image are similar in rea…

LC-FDNet: Learned Lossless Image Compression With Frequency Decomposition Network

CVPR 2022poster

Recent learning-based lossless image compression methods encode an image in the unit of subimages and achieve comparable performances to conventional non-learning algorithms. However, these methods do not consider the performance drop in the high-frequency region, giving equal consideration to the l…

Transfer Learning From Synthetic to Real-Noise Denoising With Adaptive Instance Normalization

CVPR 2020poster

Real-noise denoising is a challenging task because the statistics of real-noise do not follow the normal distribution, and they are also spatially and temporally changing. In order to cope with various and complex real-noise, we propose a well-generalized denoising architecture and a transfer learni…

Skin detection based on multi-seed propagation in a multi-layer graph for regional and color consistency

ICASSP 2017accepted

We propose a new skin detection method based on multi-seeds propagation in a multi-layer graph representation of an image. Initially, some of nodes in the graph are set to be foreground or background seeds based on a simple Bayesian skin detector, and they are propagated through the graph to find th…
