Abstract

We propose a variational multigrid method for fast 3D interpretation of image sequences, in which a dense depth map and 3D motion are directly recovered from spatio-temporal change of intensity images without prior matching and estimation. In this paper, we adopt the multigrid methods to efficiently reduce the computational complexity of the variational method, and suggest a new variational formulation to reliably perform the 3D interpretation. We show the efficiency and effectiveness of our method through experimental results with synthetic and real images
