Fusion of 3D B-Spline Surface Patches Reconstructed from Image Sequences
, 1994 International audienceThis paper considers the problem of merging a set of distinct three dimensional B-spline surface patches, which are reconstructed from observations of the motion of occluding contours in image sequences.

On the implementation of composite free surface by B-spline
, 1991 본 논문에서는 해석적 함수로 표현할 수 없는 자유곡면으로 구성되는 2차원 물체를 형상모델링 함에 있어서 중요한 역할을 하는 비-스플라인 이론의 유용성을 고찰하고 바스키와 그린버그의 알고리즘을 이용하여 쌍3차 비-스플라인 곡면의 정으로부터 복합자유곡면을 구현하였다.In this paper, the usefulness of B-spline theory that plays an important role in geometric modeling for ...

Automatic Reconstruction of B-Spline Surfaces of Arbitrary Topological Type
, 1996 Creating freeform surfaces is a challenging task even with advanced geometric modeling systems. Laser range scanners offer a promising alternative for model acquisition---the 3D scanning of existing objects or clay maquettes.

Generalized b-spline subdivision-surface wavelets and lossless compression
, 1999 We present a new construction of wavelets on arbitrary two-manifold topology for geometry compression. The constructed wavelets generalize symmetric tensor product wavelets with associated B-spline scaling functions to irregular polygonal base mesh ...
