Morphological snakes
Found in: Computer Vision and Pattern Recognition, IEEE Computer Society Conference on
By Luis Alvarez, Luis Baumela, Pedro Henriquez, Pablo Marquez-Neila
Issue Date:June 2010
pp. 2197-2202
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. By combining the morphological operators associated to the PD...
A Morphological Approach to Curvature-Based Evolution of Curves and Surfaces
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Pablo Marquez-Neila,Luis Baumela,Luis Alvarez
Issue Date:January 2014
pp. 2-17
We introduce new results connecting differential and morphological operators that provide a formal and theoretically grounded approach for stable and fast contour evolution. Contour evolution algorithms have been extensively used for boundary detection and...
Revisiting Linear Discriminant Techniques in Gender Recognition
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Juan Bekios-Calfa, José M. Buenaposada, Luis Baumela
Issue Date:April 2011
pp. 858-864
Emerging applications of computer vision and pattern recognition in mobile devices and networked computing require the development of resource-limited algorithms. Linear classification techniques have an important role to play in this context, given their ...
Improving RANSAC for fast landmark recognition
Found in: Computer Vision and Pattern Recognition Workshop
By Pablo Marquez-Neila, Jacobo Garcia Miro, Jose M. Buenaposada, Luis Baumela
Issue Date:June 2008
pp. 1-8
We introduce a procedure for recognizing and locating planar landmarks for mobile robot navigation, based in the detection and recognition of a set of interest points. We use RANSAC for fitting a homography and locating the landmark. Our main contribution ...
Efficient Model-Based 3D Tracking of Deformable Objects
Found in: Computer Vision, IEEE International Conference on
By Enrique Muñoz, José M. Buenaposada, Luis Baumela
Issue Date:October 2005
pp. 877-882
Efficient incremental image alignment is a topic of renewed interest in the computer vision community because of its applications in model fitting and model-based object tracking. Successful compositional procedures for aligning 2D and 3D models under weak...
Efficient Appearance-Based Tracking
Found in: Computer Vision and Pattern Recognition Workshop
By José Miguel Buenaposada, Enrique Muñoz, Luis Baumela
Issue Date:July 2004
pp. 6
One of the major challenges that visual tracking algorithms face nowadays is being able to cope with changes in the appearance of the target during tracking. Linear sub-space models have been extensively studied recently and are possibly the most popular w...
Real-Time Tracking and Estimation of Plane Pose
Found in: Pattern Recognition, International Conference on
By José Miguel Buenaposada, Luis Baumela
Issue Date:August 2002
pp. 20697
In this paper we present a method to estimate in real-time the position and orientation of a previously viewed planar patch. The algorithm is based on minimising the sum of squared differences between a previously stored image of the patch and the current ...
