Article Reference An Evolutive Approach for Smile Recognition in Video Sequences
by Modesto Castrillón Santana — published Sep 17, 2014 — last modified Jan 07, 2015 11:00 AM
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.

Conference Reference Automatic Clothes Segmentation for Soft Biometrics
by Modesto Castrillón Santana — published Jun 30, 2014
During the last decade, researchers have verified that clothing can provide information for gender recognition. However, before extracting features, it is necessary to segment the clothing region. We introduce a new clothes segmentation method based on the application of the GrabCut technique over a trixel mesh, obtaining very promising results for a close to   real time system. Finally, the clothing features are combined with facial and head context information to outperform previous results in gender recognition with a public database.

Article Reference Conteo de personas con un sensor RGBD comercial
by Modesto Castrillón Santana — published Jun 30, 2014 — last modified Jul 08, 2014 05:51 PM
En este trabajo se demuestra que la informacón de profundidad proporcionada por una cámara RGBD comercial de bajo coste, es una fuente fiable de datos para realizar de forma robusta el conteo automático de personas. La adopción de una configuración de vista cenital reduce la complejidad del problema, al mismo tiempo que permite preservar la      privacidad de las personas monitorizadas. Para llevar a cabo el estudio experimental se han considerado dos técnicas propias del campo de análisis de imágenes 2D trasladadas al contexto de imágenes de profundidad. Las pruebas evaluaron su rendimiento con vídeos reales sin restricciones de iluminación, incluyendo episodios de iluminación cambiante o   muy baja. En este conjunto experimental se realizó la detección, seguimiento y análisis de patrones de comportamiento de las personas que cruzaban el campo de visión. Los resultados obtenidos alcanzan una tasa de acierto próxima al 95%, superando los obtenidos con técnicas actuales basadas exclusivamente en información visual. Estos resultados  sugieren la utilidad del uso de información de profundidad en esta tarea particular.
