Curvature Estimation from Orientation Fields
نویسنده
چکیده
We propose a new curvature estimator, which operates on the output of an orientation estimator. Robust orientation estimators have been available for a long time. Some properties of the estimator as well as potential problems and limitations are discussed. The theory is verified by some experiments and practical limitations are investigated. The method is robust and performs well over a wide range of signal to noise ratios, down to about 0 dB.

Estimation of Curvature Based Shape Properties of Surfaces in 3D Grey-Value Images
Surfaces can be described locally and classified by their curvature values at every point. In this paper we investigate a grey-level based curvature estimator in combination with a sampling-error free integration technique of the curvature image. We compute shape descriptors as the bending energy and a global topological invariant, the Euler characterization. The integration of curvature values...
متن کاملLocal Curvature from Gradients of the Orientation Tensor Field
This paper presents an algorithm for estimation of local curvature from gradients of a tensor field that represents local orientation. The algorithm is based on an operator representation of the orientation tensor, which means that change of local orientation corresponds to a rotation of the eigenvectors of the tensor. The resulting curvature descriptor is a vector that points in the direction ...
متن کاملEstimation of Source Location Using Curvature Analysis
A quadratic surface can be fitted to potential-field data within 3×3 windows, which allow us to calculate curvature attributes from its coefficients. Phillips (2007) derived an equation depending on the most negative curvature to obtain the depth and structural index of isolated sources from peak values of special functions. They divided the special functions into two categories: Model-specific...
متن کاملThe Monogenic Curvature Scale-Space
In this paper, we address the topic of monogenic curvature scale-space. Combining methods of tensor algebra, monogenic signal and quadrature filter, the monogenic curvature signal, as a novel model for intrinsically two-dimensional (i2D) structures, is derived in an algebraically extended framework. It is unified with a scale concept by employing damped spherical harmonics as basis functions. T...
متن کاملEstimation of Curvature of n-dimensional Space Curves in Grey-value Images
Local curvature represents an important shape parameter of space curves which are well described by differential geometry. We have developed an estimator for local curvature of space curves embedded in nD grey-value images. There is neither a segmentation of the curve needed nor a parametric model assumed. Our estimator works on the orientation field of the space curve. This orientation field a...
