METHOD OF INCREASING VISUAL INFORMATION CONTENT OF DIGITAL GREYSCALE IMAGES Russian patent published in 2012 - IPC G06K9/40 

Abstract RU 2448367 C1

FIELD: information technology.

SUBSTANCE: method involves parallel processing of the component of each decomposition level; brightness-contract transformation parameters are determined by forming a function for correcting brightness levels and a function for correcting contrast, forming a matrix of correction factors for third level decomposition contrast using the function for correcting contrast, reconstructing the family of matrices of scaled contrast correction factors for spatial matching on each level of correction factors with values of the detail component.

EFFECT: high quality of displaying digital images.
