Similarity Registration for Shapes Based on Signed Distance Functions
نویسندگان
چکیده
A fast algorithm for similarity registration for shapes with various topologies is put forward in this paper. Fourier transform and Geometric moments are explored here to calculate the rotation, scaling and translation parameters to register two shapes by minimizing a dissimilarity measure introduced in the literature. Shapes are represented by signed distance functions. In comparison with the algorithms in the literature, the algorithm proposed here demonstrates superior performance for the registration of two shapes with various topologies as well as two shapes, each containing various and different numbers of shape components. The registration process using this algorithm is robust in comparison with the shape registration algorithms in the literature and is as fast as a couple of FFTs.

Robust Rigid Shape Registration Method Using a Level Set Formulation
This paper presents a fast algorithm for robust registration of shapes implicitly represented by signed distance functions(SDFs). The proposed algorithm aims to recover the transformation parameters(scaling, rotation, and translation) by minimizing the dissimilarity between two shapes. To achieve a robust and fast algorithm, linear orthogonal transformations are employed to minimize the dissimi...
متن کاملA Solution to the Similarity Registration Problem of Volumetric Shapes
This paper provides a novel solution to the volumetric similarity registration problem usually encountered in statistical study of shapes and shape-based image segmentation. Here, shapes are implicitly represented by characteristic functions (CFs). By mapping shapes to a spherical coordinate system, shapes to be registered are projected to unit spheres and thus, rotation and scale parameters ca...
متن کاملOn the Representation of Shapes Using Implicit Functions
In this chapter, we explore shape representation, registration and modeling through implicit functions. To this end, we propose novel techniques to global and local registration of shapes through the alignment of the corresponding distance transforms, that consists of defining objective functions that minimize metrics between the implicit representations of shapes. Registration methods in the s...

This paper deals with the problem of testing statisticalhypotheses when the available data are fuzzy. In this approach, wefirst obtain a fuzzy test statistic based on fuzzy data, and then,based on a new signed distance between fuzzy numbers, we introducea new decision rule to accept/reject the hypothesis of interest.The proposed approach is investigated for two cases: the casewithout nuisance p...
متن کاملEvaluation of Similarity Measures for Template Matching
Image matching is a critical process in various photogrammetry, computer vision and remote sensing applications such as image registration, 3D model reconstruction, change detection, image fusion, pattern recognition, autonomous navigation, and digital elevation model (DEM) generation and orientation. The primary goal of the image matching process is to establish the correspondence between two ...
