| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper we perform a comparative study of two projective reconstruction algorithms: the CBC method proposed in our previous work and a projective factorization based on the subspace iteration. To do this, we extend the subspace method for dealing with missing data, by combining iterative factorization method introducing some complexity reduction technique. The resulting subspace method alternately estimates the projective depth and the matrix factors using iterative method. Experiments carried out on both synthetic and real data clearly show that, compared to the extended subspace method, the CBC method which requires no iterative procedure efficiently produces reconstruction results with practical quality for visual reconstruction. |
