Visual hull-based prediction framework for 3D object coding
SS Hwang, S Kim, SD Kim… - 2012 Picture Coding …, 2012 - ieeexplore.ieee.org
In this paper, we propose a visual hull-based predictive framework for compressing depth
data of a 3D object. Given a 3D object represented by layered depth image, we obtain a
visual hull as a model. Then we compute and encode prediction residuals between the
visual hull and the original 3D object. We first explain the merits of a visual hull in terms of
prediction accuracy, computational costs, and efficient encoding of a model, and then we
show the overall process of the proposed method.
