DropletVideo: A Dataset and Approach to Explore Integral Spatio-Temporal Consistent Video Generation

ICCV 2025poster

Spatio-temporal consistency is a critical topic in video generation. A qualified generated video segment must ensure plot plausibility and coherence while maintaining visual consistency of objects and scenes across varying viewpoints. Prior research, especially in open-source projects, primarily foc…

Improving Height Prediction for Vision-Based Roadside 3D Object Detection

ICASSP 2025accepted

Roadside vision-based 3D object detection is vital in many applications, such as autonomous driving. The mainstream methods enhance the accuracy of distance estimation by converting predicted height distribution into depth distribution. However, predicting object’s height in roadside perception is c…

MMEditor: Multimodal Prompt-Driven 3D Gaussian Splatting Editing

ICASSP 2025accepted

We propose a multimodal 3D scene editing framework MMEditor to create or modify objects within an extant 3D Gaussian Splatting (3DGS) according to text and image prompts. MMEditor employs a multimodal image editing module to iteratively optimize 3D Gaussians in editing regions for delicate and multi…

CSOT: Cross-Scan Object Transfer for Semi-Supervised LiDAR Object Detection

ECCV 2024poster

"Large-scale 3D bounding box annotation is crucial for LiDAR object detection but comes at a high cost. Semi-supervised object detection (SSOD) offers promising solutions to leverage unannotated data, but the predominant pseudo-labeling approach requires careful hyperparameter tuning for training on…

Image Content Generation with Causal Reasoning

AAAI 2024technical

The emergence of ChatGPT has once again sparked research in generative artificial intelligence (GAI). While people have been amazed by the generated results, they have also noticed the reasoning potential reflected in the generated textual content. However, this current ability for causal reasoning…

Infer Induced Sentiment of Comment Response to Video: A New Task, Dataset and Baseline

NeurIPS 2024poster

Existing video multi-modal sentiment analysis mainly focuses on the sentiment expression of people within the video, yet often neglects the induced sentiment of viewers while watching the videos. Induced sentiment of viewers is essential for inferring the public response to videos and has broad appl…

Enhancing Network by Reinforcement Learning and Neural Confined Local Search

IJCAI 2023poster

It has been found that many real networks, such as power grids and the Internet, are non-robust, i.e., attacking a small set of nodes would cause the paralysis of the entire network. Thus, the Network Enhancement Problem~(NEP), i.e., improving the robustness of a given network by modifying its struc…

You Get What You Sow: High Fidelity Image Synthesis with a Single Pretrained Network

IJCAI 2021poster

State-of-the-art image synthesis methods are mostly based on generative adversarial networks and require large dataset and extensive training. Although the model-inversion-oriented branch of methods eliminate the training requirement, the quality of the resulting image tends to be limited due to the…
