Abstract

Computer vision and image processing techniques Interpolation and function approximation (numerical analysis) Optical, image and video signal processing
The surface normals of a 3D human model, generated form multiple viewpoint capture, are refined using an iterative variant of the shape-from-shading technique to recover fine details of clothing enabling relighting of the model according to a new virtual environment. The method requires the images to consist of a number of uniformly coloured surface patches.
