Conference Reference Evaluation of LBP and HOG Descriptors for Clothing Attribute Description
por Modesto Castrillón Santana — publicado 09/09/2014 — Última modificación 09/09/2014 15:18
In this work an experimental study about the capability of the LBP, HOG descriptors and color for clothing attribute classication is presented. Two dierent variants of the LBP descriptor are considered, the original LBP and the uniform LBP. Two classiers, Linear SVM and Random Forest, have been included in the comparison because they have been frequently used in clothing attributes classication. The experiments are carried out with a public available dataset, the clothing attribute dataset, that has 26 attributes in total. The obtained accuracies are over 75% in most cases, reaching 80% for the necktie or sleeve length attributes.

Conference Reference Kinship Verification in the Wild: The First Kinship Verification Competition
por Modesto Castrillón Santana — publicado 09/09/2014 — Última modificación 07/01/2015 13:33
Kinship verification from facial images in wild conditions is a relatively new and challenging problem in face analysis. Several datasets and algorithms have been proposed in recent years. However, most existing datasets are of small sizes and one standard evaluation protocol is still lack so that it is difficult to compare the performance of different kinship verification methods. In this paper, we present the Kinship Verification in the Wild Competition: the first kinship verification competition which is held in conjunction with the International Joint Conference on Biometrics 2014, Clearwater, Florida, USA. The key goal of this competition is to compare the performance of different methods on a new-collected dataset with the same evaluation protocol and develop the first standardized benchmark for kinship verification in the wild.

Article Reference An Evolutive Approach for Smile Recognition in Video Sequences
por Modesto Castrillón Santana — publicado 17/09/2014 — Última modificación 07/01/2015 11:00
Facial expression recognition is one of the most challenging research areas in the image recognition field and has been actively studied since the 70’s. For instance, smile recognition has been studied due to the fact that it is considered an important facial expression in human communication, it is therefore likely useful for human-machine interaction. Moreover, if a smile can be detected  and also its intensity estimated, it will raise the possibility of new applications in the future. We are talking about quantifying the emotion at low computation cost and high accuracy. For this aim, we have used a new support vector machine (SVM) based approach that integrates a weighted combination of local binary patterns (LBPs) and principal component analysis (PCA) based  approaches. Furthermore, we construct this smile detector considering the evolution of the emotion along its natural life cycle. As a consequence, we achieved both low computation cost and high performance with video sequences.

Article Reference Differential evolution and underwater glider path planning applied to the short-term opportunistic sampling of dynamic mesoscale ocean structures
por Modesto Castrillón Santana — publicado 19/09/2014 — Última modificación 19/09/2014 18:53
This paper presents an approach where differential evolution is applied to underwater glider path planning. The objective of a glider is to reach a target location and gather research data along its path by propelling itself underwater and returning periodically to the surface. The main hypothesis of this work is that gliders operational capabilities will benefit from improved path planning, especially when dealing with opportunistic short-term missions focused on the sampling of dynamic structures. To model a glider trajectory, we evolve a global underwater glider path based on the local kinematic simulation of an underwater glider, considering the daily and hourly sea currents predictions. The global path is represented by control points where the glider is expected to resurface for communication with a satellite and to receive further navigation instructions. Some well known differential evolution instance algorithms are then assessed and compared on 12 test scenarios using the proposed approach. Finally, a real case glider vessel mission was commanded using this approach.
