A process for the reduction of noise structures in the array of pixel values

摘要

A process for the reduction of noise structures in images (a, b), consisting of the array of pixel values, by the fitting together of two images (a, b) of the same object to a complete picture (r),with the following steps:a) receiving or generation of the two images (a, b) of the same object, as far as possible, the same or different geometrical conditions in a defined manner,b) transformation (θ) of a suitable image (a) of the two images (a, b) of the same object in a transformed image (a · θ), so that the information is locally in a plurality of frequency bands,c) dismantling (z) of the images (a, b) into a plurality of frequency bands so as to match the transformation (θ) in step b),d) local determination of a discrepancy operational gate (d) in step c) for the generated frequency bands (a · z, b · z) by means of the arccosine of a degree of homology measure (h) calculated from the local comparison of the generated frequency bands (a · z, b · z), in particular by calculation of the frequency-dependent correlation of the split images (a · z, b · z),e) local..
