Abstract:
1. A method for segmenting image sets, comprising: defining deformation in a computer by at least one four-dimensional control point in a deformation area defined in in three spatial coordinates and a temporal coordinate, wherein the deformation area is spatially and temporally constrained, modifying in a computer a content of said deformation area around said control point, wherein the modifying comprises transforming spatial and temporal coordinates of a point in the deformation area, wherein said transforming happens according to a vector field defined in terms of a transformation of said control point and difference between said control point and said point in the deformation area, the difference being calculated using spatial and temporal coordinates, wherein a norm of the transformation vector of said vector field at the control point is ∥V∥, and wherein the norm of the transformation vector of said vector field is shorter than ∥V∥ at a border of the deformation area, and repeating the defining deformation and the modifying.
