MIS-NeRF: neural radiance fields in minimally-invasive surgery. [PDF]
Int J Comput Assist Radiol SurgAbstract Purpose Minimally-invasive surgery (MIS) reduces the trauma compared to open surgery but is challenging for endophytic lesion localisation. Augmented reality (AR) is a promising assistance, which superimposes a preoperative 3D lesion model onto the MIS images.

Multi‐Spectral Gaussian Splatting with Neural Color Representation
Computer Graphics Forum, EarlyView.Abstract 3D Gaussian Splatting (3DGS) [KKLD23] has transformed novel‐view synthesis from RGB images, yet remains restricted to the visible spectrum. Many applications, including agricultural monitoring, rely on multi‐spectral imaging, where spectral camera alignment and scalability pose major challenges.

See4D: Pose‐Free 4D Generation via Auto‐Regressive Video Inpainting
Computer Graphics Forum, EarlyView.Abstract Immersive applications call for synthesizing spatiotemporal 4D content from casual videos without costly 3D supervision. Existing video‐to‐4D methods typically rely on manually annotated camera poses, which are labor‐intensive and brittle for in‐the‐wild footage.
