Convolution Coefficient Database for Multidimensional Least-Squares Filters

This database contains convolution coefficient matrices for symmetric kernels and both symmetric and asymmetric polynomials, in the 1, 2, 3, and 4 dimensional spaces. The kernel nodes lie at the vertices of the squares of side-length equal to unity. Please go through README.pdf for more usage details.

Before starting to download the matrix files, please verify whether a desired convolution coefficient file is available in the database or not, by looking at the following files, which list the available matrices for the 1, 2, 3, and 4 dimensional kernels, respectively.


Convolution coefficient files:
  • Folder containing individual 4D files - 4D
