The most common scheme for estimating the orientation field of space-varying directional textures is based on a local nonlinear spatial averaging of the gradient field. This leads to locally biased orientations, especially in regions of nonlinearly distributed convergence, asymmetrically distributed curvature, or geometry superposition. In this paper, we propose an orientation estimation framework that is invariant toward the local geometry. Instead of applying the spatial averaging in the…

A novel algorithm for computing the orientation field for a flowlike texture that is provably optimal in estimating the local orientations of an oriented texture and a measure of coherence which is based on the use of the angle and coherence images as intrinsic images.

Estimators for Orientation and Anisotropy in Digitized Images

This paper describes a technique for characterization and segmentation of anisotropic patterns that exhibit a single local orientation. Using Gaussian derivatives we construct a gradient-square

Adaptive Structure Tensors and their Applications

This chapter wants to give an overview of the different approaches to the computation of the structure tensor, whereas the focus lies on the methods based on robust statistics and nonlinear diffusion.

Structure tensor field regularization based on geometric features

This paper proposes a new dissimilarity measure combining two terms devoted respectively to the orientation and to the shape component of the tensor, and shows that relevant information can be extracted by enhancing the seismic structures identification.

Geodesic Active Contours

A novel scheme for the detection of object boundaries based on active contours evolving in time according to intrinsic geometric measures of the image, allowing stable boundary detection when their gradients suffer from large variations, including gaps.

Optimal Orientation Detection of Linear Symmetry

The problem of optimal detection of orientation in arbitrary neighborhoods is solved in the least squares sense. It is shown that this corresponds to fitting an axis in the Fourier domain of the

This paper proposes a new method to synthesize and inpaint geometric textures. The texture model is composed of a geometric layer that drives the computation of a new grouplet transform. The geometry

Vector-valued image regularization with PDEs: a common framework for different applications

A unifying expression is proposed that gathers the majority of PDE-based formalisms for vector-valued image regularization into a single generic anisotropic diffusion equation, allowing us to implement the authors' regularization framework with accuracy by taking the local filtering properties of the proposed equations into account.

A variational framework is proposed that incorporates a small set of good features for texture segmentation based on the structure tensor and nonlinear diffusion in a level set based unsupervised segmentation process that adaptively takes into account their estimated statistical information inside and outside the region to segment.

Texture Synthesis Using the Structure Tensor

This paper proposes a two-stage texture synthesis algorithm that is tested on various textures and compared objectively with existing methods, highlighting its strength in successfully synthesizing the output texture in many situations where traditional algorithms fail to reproduce the exemplar's patterns.
