Real{time Head Tracking by Saccadic Exploration and Gabor Decomposition

Facial Feature Detection by Saccadic Exploration of the Gabor Decomposition

The Gabor decomposition is a ubiquitous tool in computer vision. Nevertheless, it is generally considered computationally demanding for active vision applications. We suggest an attention{driven approach to feature detection inspired by the human saccadic system. A dramatic speedup is achieved by computing the Gabor decomposition only on the points of a sparse retinotopic grid. An application t...

Saccadic search with Gabor features applied to eye detection and real-time head tracking

Real-time tracking and imitation of facial expression

We present a system for tracking facial expression and head pose with one camera and no special markers, and generating a face animation to imitate these expressions simultaneously. The tracking is based on Gabor wavelet coefficients (jets) of the facial feature points, a saccadic searching strategy, and a model-based adjustment. Using Principal Components Analysis (PCA), we established an expr...

Facial Features detection by Saccadic Exploration of the Gabor decomposition and Support Vector Machines

Facial features detection is of primary importance to face authentication and recognition. In this paper, we present an attention{driven approach to eyes and mouth detection inspired by the human saccadic system. The algorithm is centred around a log{polar retinotopic grid that is used to sample the Gabor decomposition of the image. Detection is achieved by displacing the grid according to a sa...
