Feature Selection Using Genetic Algorithms for Hand Posture Recognition
Feature Selection Using Genetic Algorithms for Hand Posture Recognition
Uriel H. Hernandez-Belmonte, Victor Ayala-Ramirez
Abstract
In this work, we propose a feature selection algorithm to perform hand posture recognition. The hand posture recognition is an important task to perform the human-computer interaction. The hand is a complex object to detect and recognize. That is because the hand morphology varies from human to human. The object recognition community has developed several approaches to recognize hand gestures, but still, there are not a perfect system to recognize hand gestures under diverse conditions and scenarios. We propose a method to perform the hand recognition based on feature selection. The feature selection is performed by a genetic algorithm that combines several features to build a descriptor. The evolved descriptor is used to train a perceptron, which is used as a weak classifier. Each weak learner is used in the AdaBoost algorithm to build a strong classifier. To test our approach, we use a standard image dataset and the full image evaluation methodology. The results were compared with a state of the art algorithm. Our approach demonstrated to be comparable with this algorithm and improve its performance in the some of the cases.
