....self shading and illumination change. The eigenface method has been extended to view based and modular eigenspaces with the intention of recognising faces under varying views by Moghaddam and Pentland [20] Li et al. 17] presented a view based piece wise SVM model of the face space. Cootes et al. [10] proposed the view based Active Appearance Models which employ three models for profile, half profile and frontal views. But the division of the face space in these methods is rather arbitrary, ad hoc and often coarse. Another limitation of the previous work is that the methods proposed for ....

....of the 2D appearance. To address this problem, Romdhani et al. [15] developed a multi view appearance model using Kernel Principal Component Analysis (KPCA) The non linearity of KPCA enables the model to deal with large pose variation, but has a price of intensive computation. Cootes et al. [4] proposed the view based Active Appearance Models which employ three models for profile, half profile and frontal views. On the other hand, Moghaddam and Pentland [13] presented a view based and modular eigenspace method. Li et al. 12] introduced a view based piece wise SVM (Support Vector ....

Facial expression modeling The aim of this section is to study a linear model, as it is proposed in [11, 12], correlating the appearance parameters to facial expression intensity according to: c = ae0 ae1 I # (5) where I is a scalar varying from I =0to indicate neutral expression to I =1to indicate a high magnitude expression and # is the approximation error. ae0 and ae1 are coefficient vectors ....

....(in the sense of [4] and placed in correspondence. We automatically construct a light field morphable model of facial appearance from real images, and show how that model can be automatically matched to single static intensity images. Our model differs from the multi view appearance model of [10] in that coefficients between views are explicitly linked, and that we do not model any pose variation within the shape model at a single view. Additionally we can render appearances with view dependent texture effects, and use a densely sampled camera array. We construct our face model using ....

....of motion [2] A model appropriate for feature point locations sampled from a contour is also given in [2] This single view approach can be extended to 3D by considering multiple simultaneous views of features. Shape models in several views can be separately estimated to match object appearance [5]; this approach was able to learn a mapping between the low dimensional shape parameters in each view. With multi view contours from cameras at known locations, a visual hull can be recovered to model the shape of the observed object [11] Algorithms for fast rendering of image based visual ....

.... of pattern recognition, many systems have been described that locate and recognize facial features on the human head [2] Most facial recognition systems focus on recognizing the identity of persons on an image [34] recognizing facial expressions [19] 29] or tracking the pose of heads on images [1]. Most of these systems are tuned for locating facial parts with reasonable accuracy (within about five pixels) on a large database of different subjects. To be able to synthesize a photo realistic talking head, we need to locate the position of facial parts with subpixel accuracy. Misalignment ....
