Physics-Grounded Attached Shadow Detection Using Approximate 3D Geometry and Light Direction

arXiv — cs.CVTuesday, December 9, 2025 at 5:00:00 AM
  • A new framework for detecting attached shadows has been introduced, addressing the challenge of identifying areas on occluders where light cannot reach due to self-occlusion. This system combines a shadow detection module for both cast and attached shadows with a light estimation module that infers light direction, enhancing scene understanding and object structure definition.
  • This development is significant as it fills a gap in existing shadow detection methods, which primarily focus on cast shadows. By jointly detecting both shadow types, the framework improves the accuracy of 3D scene analysis, which is crucial for applications in computer vision and robotics.
  • The introduction of this framework aligns with ongoing advancements in 3D geometry reconstruction and scene understanding, highlighting the importance of accurate shadow detection in various AI applications. As researchers explore methods for enhancing 3D data interpretation, the integration of geometry and illumination in shadow detection represents a critical step towards more sophisticated visual recognition systems.
