This paper proposes real-time face tracking and recognition by combining two eigen-based methods. The first method is a novel extension of eigenface called augmented eigenface and the second method is a sparse 3D eigentemplate tracker controlled by a particle filter. The augmented eigenface is an eigenface augmented by an associative mapping to 3D shape that is specified by a set of volumetric face...
This paper introduces a novel method to automatically synthesizing frontal view face images from more than one ill-posed face images. Rather than relying on a uniform warping function to the whole image, our deformation strategy is specific to each pixel. And rather than relying on inaccurate pose estimation, the contribution of each input image is determined automatically to minimize the non-rigid...
We present a stochastic filtering approach to perform albedo estimation from a single non-frontal face image. Albedo estimation has far reaching applications in various computer vision tasks like illumination-insensitive matching, shape recovery, etc. We extend the formulation proposed in that assumes face in known pose and present an algorithm that can perform albedo estimation from a single image...
In this paper, we present a full-automatic Spatio-Temporal GrabCut human segmentation methodology. GrabCut initialization is performed by a HOG-based subject detection, face detection, and skin color model for seed initialization. Spatial information is included by means of Mean Shift clustering whereas temporal coherence is considered by the historical of Gaussian Mixture Models. Moreover, human...
In this paper, we present some extensions to Active Appearance Model and its extended view-based models are applied for tracking faces through wide angles. The extensions include:(1) a new multiband representation created by filtering the images with a set of orthogonal spatial filters and then applying a non-linear normalization to them, and (2)adding extra landmarks outside the facial region to...
