Title:

直接因数分解による変形可能な形状のレジストレーション及びモデリングのためのシステム及び方法

Document Type and Number:

Japanese Patent JP2008511932

Kind Code:

A

Abstract:

A method of registering and modeling a deformable shape in a digitized image is provided, comprising the steps of providing a measurement matrix W of N measurements of P points of a D-dimensional deformable shape, determining a basis number K for the N measurements, wherein K

M_{i} Q_{k} M_{j}^{T} = {\begin{matrix} I_{D x D}, i = j = k \\ 0_{D x D}, (i, j) \in Phi \end{matrix},

where Phi stands for {(i, j)|i=1, . . . , K; j=1, . . . , N, igammak}, which represents an ambiguity matrix transforming the proposed scaled rotation matrix and the proposed basis matrix into a true scaled rotation matrix and a true basis matrix; decomposing the matrix Qk into gkgkT, for k=1, . . . , K, wherein gk is a column of a D∃K%D∃K matrix G; and recovering the true scaled rotation matrix from Mx∃G and the true basis matrix from G-1x∃B.
