초록

The method identifies a Pixon element, which is a fundamental and indivisible unit of information, and a Pixon basis, which is the set of possible functions from which the Pixon elements are selected. The actual Pixon elements selected from this basis during the reconstruction process represents the smallest number of such units required to fit the data and representing the minimum number of parameters necessary to specify the image. The Pixon kernels can have arbitrary properties (e.g., shape size, and/or position) as needed to best fit the data.

1. In an image reconstruction process, a method for generating a kernel map for modeling an image wherein the image corresponds to a plurality of input data points on an image grid comprising a plurality of grid points, the method comprising:(a) defining a plurality of different kernel sets, each different kernel set comprising a plurality of identical kernels covering the image grid, wherein each kernel within a kernel set covers a portion of the image grid encompassing a portion of the plurality of data points so that the plurality of kernels of a kern...
