Title:
A boundary specific device, a boundary specific method, a program, and a recording medium
Document Type and Number:
Japanese Patent JP6070377
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To achieve a boundary specification device that can specify, assuming that a boundary of an area D included in a position space Rof an image I as δD, a boundary along the edge of the image I.SOLUTION: A boundary specification device 1 includes an image manifold generation unit 11 that generates an image manifold M corresponding to an image I, a scalar field generation unit 14 that generates a scalar field f satisfying predetermined constraint conditions at a constraint point on the image manifold M, and a zero level set derivation unit 15 that derives a zero level set Z of the scalar field f.
