Abstract

Behavior recognition has been one of the hot topics in the field of computer vision and its application. The popular appearance-based behavior classification methods often utilize sparse spatio-temporal features that capture the salient features and then use a visual word dictionary to construct visual words. Visual word assignments based on K-means clustering are very effective and behave well for general behavior classification. However, these pipelines often demand high computational power for the stages for low visual feature extraction and visual word assignment, and thus they are not suitable for real-time recognition tasks. To overcome the inefficient processing of K-means and the nearest neighbor approach, an ensemble approach is used for fast processing. For real-time recognition, an ensemble of random trees seems particularly suitable for visual dictionaries owing to its simplicity, speed, and performance. In this paper, we focus on the real-time recognition by utilizing a random clustering forest and verifying its effectiveness by classifying various hand gestures. In addition, we proposed a boosted random clustering forest so that training time can be successfully shortened with minimal negative impact on its recognition rate. For an application, we demonstrated a possible use of real-time gesture recognition by controlling a digital TV using hand gestures.
