HeroGS: Hierarchical Guidance for Robust 3D Gaussian Splatting under Sparse Views

CVPR 2026

3D Gaussian Splatting (3DGS) has recently emerged as a promising approach in novel view synthesis, combining photorealistic rendering with real-time efficiency. However, its success heavily relies on dense camera coverage; under sparse-view conditions, insufficient supervision leads to irregular Gau

Seeing Is Believing: Grounding Long-Video Understanding in Spatio-Temporal Visual Evidence

AAAI 2026technical

Although Vision Language Models (VLMs) have excelled at image and video understanding, applying them to hour-long videos is held back by two interrelated challenges: exorbitant computational expense and a qualitative breakdown in long-term temporal reasoning. Thus, models tend to generate answers ba

Semantic-aware SAM for Point-Prompted Instance Segmentation

CVPR 2024highlight

Single-point annotation in visual tasks with the goal of minimizing labeling costs is becoming increasingly prominent in research. Recently visual foundation models such as Segment Anything (SAM) have gained widespread usage due to their robust zero-shot capabilities and exceptional annotation perfo…
