CC-VQA: Conflict- and Correlation-Aware Method for Mitigating Knowledge Conflict in Knowledge-Based Visual Question Answering

Yuyang Hong, Jiaqi Gu, Yujin Lou +7

Knowledge-based visual question answering (KB-VQA) demonstrates significant potential for handling knowledge-intensive tasks. However, conflicts arise between static parametric kno…

Sketch-in-Latents: Eliciting Unified Reasoning in MLLMs

Jintao Tong, Jiaqi Gu, Yujing Lou +5

While Multimodal Large Language Models (MLLMs) excel at visual understanding tasks through text reasoning, they often fall short in scenarios requiring visual imagination. Unlike c…

NoPe-NeRF++: Local-to-Global Optimization of NeRF with No Pose Prior

Dongbo Shi, Shen Cao, Bojian Wu +5

In this paper, we introduce NoPe-NeRF++, a novel local-to-global optimization algorithm for training Neural Radiance Fields (NeRF) without requiring pose priors. Existing methods,…

TrackGS: Optimizing COLMAP-Free 3D Gaussian Splatting with Global Track Constraints

Dongbo Shi, Shen Cao, Lubin Fan +4

We present TrackGS, a novel method to integrate global feature tracks with 3D Gaussian Splatting (3DGS) for COLMAP-free novel view synthesis. While 3DGS delivers impressive renderi…

Knowledge-based Visual Question Answer with Multimodal Processing, Retrieval and Filtering

Yuyang Hong, Jiaqi Gu, Qi Yang +6

Knowledge-based visual question answering (KB-VQA) requires visual language models (VLMs) to integrate visual understanding with external knowledge retrieval. Although retrieval-au…

SD-VLM: Spatial Measuring and Understanding with Depth-Encoded Vision-Language Models

Pingyi Chen, Yujing Lou, Shen Cao +6

While vision language models (VLMs) excel in 2D semantic visual understanding, their ability to quantitatively reason about 3D spatial relationships remains under-explored, due to…
