Garment pattern optimized identification based on non-uniform B-spline wavelet and its application;

Digital image watermarking algorithm based on non-uniform B-spline wavelets transformation;

A new algorithm for embedding and extracting watermark in the domain of middle frequency of the carrier im-ages is presented which is based on non-uniform B-spline wavelet transformation.

The decomposition and reconstruction of one-dimensional non-uniform B-spline wavelets is introduced and then is extended to two-dimensional images.

The applications of non-uniform B-spline wavelets in geometric modelling can be found in many literatures, but that in digital watermarking is .

In this paper, we extend Finkelstein’s work to arbitrary non-uniform B-spline wavelets.

DTM interpolation model based on non-uniform B-splines;

Application of non-uniform B-spline least square in GPS leveling height fitting;

Based on the skirt removed approach under the non-uniform Catmull-Clark subdivision scheme,an efficient algorithm is given for points and normals interpo- lation of non-uniform B-spline surfaces by defining templates in subdivision meshes and adjusting positions of subdivision mesh vertices.

Quadratic mixed functional uniform B splines with shape parameters;

The paper presents the basis function of k-th degree uniform B-spline with a shape parameter.

For region of interest and background region a method was proposed, which is used to represent the uniform B-spline surfaces by different resolution.

For uniform B-spline curves and surfaces, a unified expression can be adopted after decomposition to describe the wavelets for the interior and boundaries of the domain defined, and hence the multiplication is the only operation be needed to wavelets reconstruction.
