Factorization with missing
and degenerate data The 3D model of "Casa da Musica" is computed from point coordinates in the images. Main contributions: - Uncalibrated reconstruction (images obtained on google images). - Very dissimilar images - Visible are can be degenrate (planar). State of the art brakes down. This method was used for face recognition . |
