Dominant Local Binary Patterns for Texture Classification

TL;DR: The proposed features are robust to image rotation, less sensitive to histogram equalization and noise, and achieves the highest classification accuracy in various texture databases and image conditions.
Book ChapterDOI

Three Dimensional Curvilinear Structure Detection Using Optimally Oriented Flux

TL;DR: In this article, the authors proposed a novel curvilinear structure detector, called Optimally Oriented Flux (OOF), which finds an optimal axis on which image gradients are projected in order to compute the image gradient flux.
Proceedings ArticleDOI

Facial Expression Recognition using Advanced Local Binary Patterns, Tsallis Entropies and Global Appearance Features

TL;DR: This paper proposes a novel facial expression recognition approach based on two sets of features extracted from the face images: texture features and global appearance features, obtained by using the extended local binary patterns in both intensity and gradient maps.
Proceedings ArticleDOI

Fast Symmetric Diffeomorphic Image Registration with Convolutional Neural Networks

TL;DR: A novel, efficient unsupervised symmetric image registration method which maximizes the similarity between images within the space of diffeomorphic maps and estimates both forward and inverse transformations simultaneously.
Book ChapterDOI

Large Deformation Diffeomorphic Image Registration with Laplacian Pyramid Networks

TL;DR: A deep Laplacian Pyramid Image Registration Network is proposed, which can solve the image registration optimization problem in a coarse-to-fine fashion within the space of diffeomorphic maps.
