IMAGE PROCESSING USING LINEAR PARAMETRES OF LIGHTING APPARATUS AND OTHER IMAGE PROCESSNG ENHANCEMENTS Russian patent published in 2010 - IPC G06K9/36 G06T3/20 

FIELD: information technology.

SUBSTANCE: processing involves scaling, creation of composite images, alpha blending, edge detection etc. A more specific realisation describes strategies for processing image information which: a) is linear; b) lies in the colour space RGB; c) has high accuracy (e.g. provided through floating-point representation); d) is row-wise; and e) is full-channel. Other enhancements provide strategies for: a) processing image information in pseudolinear space in order to increase rate of processing; b) realising an improved error variance technique; c) dynamic calculation and use of filtration nuclei; d) optimising pipelined code generation; and e) realising different processing tasks using novel pixel shader techniques.

EFFECT: reduced image distortion.
