Abstract
A method constructs a super-resolution texture from a sequence of images of a non-rigid three-dimensional object. A shape of the object is represented as a matrix of vertices, and a basis of possible deformations of the object is represented as a matrix of displacements of the 3D points, the matrices of 3D points and displacements form a model of the object in the video. A set of correspondences between the points in model and the object in the images is formed. The points in each image are connected using the set of correspondences to form a triangle texture mesh for each image. Each triangle mesh is warped to a common coordinate system while super-sampling texture in each image. The warped and super-sampled triangle meshes are averaged to produce the super-sampled texture of the object in the image.
