FreeViS: Training-free Video Stylization with Inconsistent References

ICLR 2026poster

Video stylization plays a key role in content creation, but it remains a challenging problem. Naïvely applying image stylization frame-by-frame hurts temporal consistency and reduces style richness. Alternatively, training a dedicated video stylization model typically requires paired video data and…

Filter Images First, Generate Instructions Later: Pre-Instruction Data Selection for Visual Instruction Tuning

CVPR 2025highlight

Visual instruction tuning (VIT) for large vision-language models (LVLMs) requires training on expansive datasets of image-instruction pairs, which can be costly. Recent efforts in VIT data selection aim to select a small subset of high-quality image-instruction pairs, reducing VIT runtime while main…

Towards Zero-Shot Anomaly Detection and Reasoning with Multimodal Large Language Models

CVPR 2025highlight

Zero-Shot Anomaly Detection (ZSAD) is an emerging AD paradigm. Unlike the traditional unsupervised AD setting that requires a large number of normal samples to train a model, ZSAD is more practical for handling data-restricted real-world scenarios. Recently, Multimodal Large Language Models (MLLMs)…

ReGS: Reference-based Controllable Scene Stylization with Gaussian Splatting

NeurIPS 2024poster

Referenced-based scene stylization that edits the appearance based on a content-aligned reference image is an emerging research area. Starting with a pretrained neural radiance field (NeRF), existing methods typically learn a novel appearance that matches the given style. Despite their effectiveness…

Wild-GS: Real-Time Novel View Synthesis from Unconstrained Photo Collections

NeurIPS 2024poster

Photographs captured in unstructured tourist environments frequently exhibit variable appearances and transient occlusions, challenging accurate scene reconstruction and inducing artifacts in novel view synthesis. Although prior approaches have integrated the Neural Radiance Field (NeRF) with additi…

Animal3D: A Comprehensive Dataset of 3D Animal Pose and Shape

ICCV 2023poster

Accurately estimating the 3D pose and shape is an essential step towards understanding animal behavior, and can potentially benefit many downstream applications, such as wildlife conservation. However, research in this area is held back by the lack of a comprehensive and diverse dataset with high-qu…

PIDNet: A Real-Time Semantic Segmentation Network Inspired by PID Controllers

CVPR 2023poster

Two-branch network architecture has shown its efficiency and effectiveness in real-time semantic segmentation tasks. However, direct fusion of high-resolution details and low-frequency context has the drawback of detailed features being easily overwhelmed by surrounding contextual information. This…
