In this paper, we propose a framework for both gradient descent image and object alignment in the Fourier domain. Our method centers upon the classical Lucas & Kanade (LK) …
The active appearance model (AAM) is a powerful method for modeling and segmenting deformable visual objects. The utility of the AAM stems from two fronts: its compact …
Convex quadratic fitting (CQF) has demonstrated great success recently in the task of non- rigidly registering a face in a still image using a constrained local model (CLM). A CLM is a …
Active appearance models (AAMs) have demonstrated great utility when being employed for non-rigid face alignment/tracking. The “simultaneous” algorithm for fitting an AAM achieves …

This paper proposes a learned data-driven approach for accurate, real-time tracking of facial features using only intensity information. The task of automatic facial feature tracking is …

This work addresses the matching of a 3D deformable face model to 2D images through a 2.5 D Active Appearance Models (AAM). We propose a 2.5 D AAM that combines a 3D …
In this paper we propose a framework for gradient descent image alignment in the Fourier domain. Specifically, we propose an extension to the classical Lucas & Kanade (LK) …

When a face is partially occluded in an image, the existing discriminative or generative methods often do not find facial features. This is due to the limitations of local facial feature …
Gaining invariance to camera and illumination variations has been a well investigated topic in Active Appearance Model (AAM) fitting literature. The major problem lies in the inability of …
