A Morphological Approach to Curvature-Based Evolution of Curves and Surfaces
TLDR
We introduce new results connecting differential and morphological operators that provide a formal and theoretically grounded approach for stable and fast contour evolution. Expand

Revisiting Linear Discriminant Techniques in Gender Recognition
TLDR
The paper reviews the state-of-the-art in gender classification, giving special attention to linear techniques and their relations. Expand

Robust gender recognition by exploiting facial attributes dependencies
TLDR
We study the dependencies among gender, age and pose facial attributes and prove that we can improve the performance of gender classifiers by exploiting these dependencies. Expand

Morphological snakes
We introduce a morphological approach to curve evolution. The differential operators used in the standard PDE snake models can be approached using morphological operations on a binary level set. ByExpand

Recognising facial expressions in video sequences
TLDR
We introduce a system that processes a sequence of images of a front-facing human face and recognises a set of facial expressions and estimate the deformation of its non-rigid components. Expand

A Deeply-Initialized Coarse-to-fine Ensemble of Regression Trees for Face Alignment
TLDR
We present DCFE, a real-time facial landmark regression method based on a coarse-to-fine Ensemble of Regression Trees (ERT) to generate probability maps of landmarks location. Expand

Towards robust metric reconstruction via a dynamic uncalibrated stereo head
TLDR
We consider the problem of metrically reconstructing a scene viewed by a moving stereo head, and show that a static stereo head constitutes a degenerate camera configuration for carrying out self-calibration. Expand

Efficient illumination independent appearance-based face tracking
TLDR
We introduce a linear subspace representation in which the appearance of a face is represented by the addition of two approximately independent linear subspaces modelling facial expressions and illumination, respectively. Expand

Real-time tracking and estimation of plane pose
TLDR
We present a method to estimate in real-time the position and orientation of a previously viewed planar patch. Expand

Multi-class segmentation of neuronal structures in electron microscopy images
TLDR
Simultaneously segmenting several neuronal structures described at different scales provides voxel classification algorithms with highly discriminating features that significantly improve segmentation accuracy. Expand
