The primal sketch model (Guo/Zhu/Wu 2003) is a parsimonious, graphical, token representation for generic natural images. Based on this representation, we compute the surface depth (2.5D sketch), following David Marr's conjecture.

We show two projects for illustration.

1. Shape from Shading based on primal sketch (Han and Zhu, CVPR 2005)

 

2. Stereo matching and reconstruction based on primal sketch (Barbu and Zhu, ICCV 2005)
