Multiview point cloud registration with anisotropic and space-varying localization noise

arXiv — cs.CVTuesday, November 25, 2025 at 5:00:00 AM
  • A new paper presents a method for registering multiple point clouds affected by high anisotropic localization noise, utilizing a Gaussian mixture model (GMM) and an expectation-maximization (EM) algorithm. This approach addresses the limitations of existing methods that assume isotropic Gaussian noise, which is often not the case in practical applications like single molecule localization microscopy (SMLM).
  • The proposed method enhances the accuracy of point cloud registration by introducing an explicit localization noise model, allowing for better handling of space-variant and anisotropic Gaussian noise. This advancement is significant for fields relying on precise spatial data, such as computer vision and microscopy, where accurate data representation is crucial.
  • This development aligns with ongoing efforts in the AI and computer vision sectors to improve data processing techniques. Innovations like the Voxel Diffusion Module for 3D object detection and advancements in low-light image enhancement reflect a broader trend towards enhancing the accuracy and efficiency of data representation and analysis in complex environments.
