METHOD FOR COMPLEXING OF DIGITAL MULTISPECTRAL HALFTONE IMAGES Russian patent published in 2020 - IPC G06T5/40 

FIELD: physics.

SUBSTANCE: invention relates to digital image processing. Technical result is achieved by obtaining initial images in L-bands, determining the highest-priority image, generating a reference image on all source images, luminance gradient values of the i^th pixel of the reference image with surrounding i ± p, j ± q pixels in a sliding window with a predetermined gain, generating a set of estimates of the ij^th pixel of the integrated image by summing the brightness values i ± p, j ± q pixels of neighbourhood of ij^th pixel in sliding window of priority image with obtained corresponding brightness gradient values of the i^th pixel of the reference image, the resulting integrated image is obtained by averaging the obtained set of estimates.

EFFECT: technical result consists in improvement of local contrast of resultant image containing elements of initial images of same scene, obtained in different spectral ranges, and increase in resistance to noise.
