1. A computer-implemented method for 3D reconstruction, the method comprising:
obtaining 2D images which all represent a same real object which is fixed, and, for each 2D image, camera parameters which define a perspective projection;
obtaining, for each 2D image, a smooth map, the smooth map having pixel values each representing a measurement of contour presence, the contour being a location of separation between two different textures of the 2D image; and
determining a 3D modeled object that represents the real object, the determining iteratively optimizing energy that rewards, for each smooth map, projections of silhouette vertices of the 3D modeled object having pixel values, on the smooth map, representing a high measurement of contour presence,
wherein the energy includes a term of a type:
where for a 2D image i:
Σi(⋅) denotes the smooth map,
sij denotes a silhouette point j, and
πi(⋅) denotes a projection transformation.
