Abstract

A method for deforming a standard 3D model based on 2D image data input, comprising the steps of: - Performing an initial deformation (100) on said standard 3D model using a detection model and a deformation model, thereby obtaining a deformed standard 3D model; - determining (200) the optical flow between the 2D image data input and the warped standard 3D model; - applying (300) the optical flow to the deformed standard 3D model, thereby providing fine-tuned 3D standard model.

Description

technical field [0001] The invention relates to a method for three-dimensional model deformation. Background technique [0002] Currently, warping of models based on realistic dynamic scenes or even images taken by cheap cameras can be a problem. Three-dimensional, which will be simply referred to as 3D in the rest of this article, model artists may eg spend a lot of time and effort creating highly detailed and realistic 3D content and 3D animations. But this situation is undesirable and even impractical in next-generation communication systems, since eg 3D visualizations of conference participants may have to be created on the fly. Contents of the invention [0003] It is therefore an object of embodiments of the present invention to present a method and apparatus for image model morphing that can be based on two-dimensional, hereafter abbreviated 2D, video scenes from even low-quality real-life picture acquisitions. to generate high-quality 3D image models and at the s...
