Using retinex for point selection in 3D shape registration
Inspired by retinex theory, we propose a novel method for selecting key points from a depth map of a 3D freeform shape; we also use these key points as a basis for shape registration. To find key points, first, depths are transformed using the Hotelling method and normalized to reduce their dependence on a particular viewpoint. Adaptive smoothing is then applied using weights which decrease wit...
متن کامل3D Shape Registration
Registration is the problem of bringing together two or more 3D shapes, either of the same object or of two different but similar objects. This chapter first introduces the classical Iterative Closest Point (ICP) algorithm which represents the gold standard registration method. Current limitations of ICP are addressed and the most popular variants of ICP are described to improve the basic imple...
متن کامل3D Registration by Using an Alternative 3D Shape Representation
Abstract: This paper introduces a surface matching algorithm for 3D registration that uses an alternative 3D Shape Representation: CIRCON (Cylindrical Image of Radial Contours), that both enables the compression of the 3D data, making them more manageable, and facilitates the tasks related to surface matching. By making use of the properties of this 3D shape representation two surfaces whose re...
متن کاملMulti-view Point Cloud Registration Using Affine Shape Distributions
Registration is crucial for the reconstruction of multi-view single plane illumination microscopy. By using fluorescent beads as fiduciary markers, this registration problem can be reduced to the problem of point clouds registration. We present a novel method for registering point clouds across views. This is based on a new local geometric descriptor affine shape distribution to represent the r...
متن کامل3D Shape Registration Using Spectral Graph Embedding and Probabilistic Matching
In this book chapter we address the problem of 3D shape registration and we propose a novel technique based on spectral graph theory and probabilistic matching. Recent advancement in shape acquisition technology has led to the capture of large amounts of 3D data. Existing real-time multi-camera 3D acquisition methods provide a frame-wise reliable visual-hull or mesh representations for real 3D ...
