On the construction of multiresolution analyses associated to general subdivision schemes

نویسندگان

چکیده

Subdivision schemes are widely used in numerical mathematics such as signal/image approximation, analysis and control of data or analysis. However, to develop their full power, subdivision should be incorporated into a multiresolution that, mimicking wavelet analyses, provides multi-scale decomposition function, curve, surface. The ingredients needed define associated scheme decimation detail operators. Their construction is not straightforward soon the non-interpolatory. This paper devoted operators compatible with general schemes, including non-linear ones. Analysis performances constructed analyses carried out. Some applications presented framework image approximation.

Construction of Ternary Approximating Subdivision Schemes

In this, an algorithm to produce ternary m-point (for any integer m ≥ 2) approximating subdivision scheme has been introduced that can generate the families of C limiting curves. The proposed scheme has developed using the uniform B-spline blending functions and its convergence is analyzed by Laurent polynomial method. It is concluded that the existing 2-point, 3-point and 5-point ternary appro...

Classification and Construction of Bivariate Subdivision Schemes

In this paper, we shall classify all possible stationary subdivision schemes on a triangular or quadrilateral regular mesh. Then we shall propose a general procedure to construct stationary subdivision schemes (subdivision triplets) with certain desired properties. Finally, we shall present some examples of C √

Analysis of a class of nonlinear subdivision schemes and associated multiresolution transforms

This paper is devoted to the convergence and stability analysis of a class of nonlinear subdivision schemes and associated multi-resolution transforms. These schemes are defined as a perturbation of a linear subdivision scheme. Assuming a contractivity property, stability and convergence are derived. These results are then applied to various schemes such as uncentered interpolatory linear schem...

Adaptive Directional Subdivision Schemes and Shearlet Multiresolution Analysis

In this paper, we propose a solution for a fundamental problem in computational harmonic analysis, namely, the construction of a multiresolution analysis with directional components. We will do so by constructing subdivision schemes which provide a means to incorporate directionality into the data and thus the limit function. We develop a new type of non-stationary bivariate subdivision schemes...
