Faces and Gestures

The aforementioned work on representation and learning has contributed to two types of human computer interfaces we have developed. First, learning and classification techniques, including usual statistical classifiers, neural networks, support vector machines and artificial intelligence approaches, have been used to develop new methods for human face detection and hand gesture recognition.

Face Recognition

To develop methods to tell the identity of a person from a frontal image and evaluate its performance with state-of-the-art methods.
