Abstract
Methods for improved reconstruction of a deforming surface may comprise canceling ambient occlusion of the deforming surface from an input image, computing an optical flow of the image, and refining a 3-D shape of the surface. Canceling ambient occlusion of the deforming surface may comprise computing the ambient occlusion of the surface, projecting the ambient occlusion onto each image plane, and then removing the ambient occlusion from the corresponding input image.
Claims22
A non-transitory computer readable medium having computer executable program code embodied thereon, the computer executable program code configured to cause a computing device to improve reconstruction of a deforming surface given a sequence of reconstructed surfaces and corresponding calibrated input images by:
- canceling ambient occlusion of the deforming surface from an input image;
- computing an optical flow of the image;
- and
- refining a 3-D shape of the surface.
A non-transitory computer readable medium having computer executable program code embodied thereon, the computer executable program code configured to cause a computing device to improve reconstruction of a deforming surface of an input image by:
- capturing input images using nearly uniform lighting from a known illumination;
- performing a geometric reconstruction on a captured image;
- computing ambient occlusion of the deforming surface;
- and
- generating a corrected image with improved optical flow.
