Combining Undersampled Dithered Images
Undersampled images, such as those produced by the HST WFPC-2, misrepresent fine-scale structure intrinsic to the astronomical sources being imaged. Analyzing such images is difficult on scales close to their resolution limits and may produce erroneous results. A set of “dithered” images of an astronomical source generally contains more information about its structure than any single undersampl...
متن کاملHuman Model Fitting from Monocular Posture Images
Marker-less motion capture systems usually rely on a 3D skin and skeleton model of the observed person. We present a system that is able to fit a template MPEG4 body model to a person from multiple views taken with a single camera. The person is observed in 6 different postures. Based on contour differences between model and person, a global nonlinear optimization method estimates the scale val...
متن کاملFitting a Single Active Appearance Model Simultaneously to Multiple Images
Active Appearance Models (AAMs) are a well studied 2D deformable model. One recently proposed extension of AAMs to multiple images is the CoupledView AAM. Coupled-View AAMs model the 2D shape and appearance of a face in two or more views simultaneously. The major limitation of CoupledView AAMs, however, is that they are specific to a particular set of cameras, both in geometry and the photometr...
متن کاملEfficient generic face model fitting to images and videos
In this paper we present a robust and lightweight method for the automatic fitting of deformable 3D face models on facial images. Popular fitting techniques such as those based on statistical models of shape and appearance require a training stage based on a set of facial images and their corresponding facial landmarks, which have to be manually labeled. Therefore, new images in which to fit th...
متن کاملFace Model Fitting on Low Resolution Images
Active Appearance Models (AAMs) represent the shape and appearance of an object via two low-dimensional subspaces, one for shape and one for appearance. AAMs for facial images are currently receiving considerable attention from the vision community. However, most existing work focuses on fitting AAMs to high-quality facial images. For many applications, effectively fitting an AAM to low-resolut...
