AUTOMATIC SKETCH GENERATION METHOD AND SYSTEM THEREFOR Russian patent published in 2015 - IPC G06K9/36 

FIELD: physics.

SUBSTANCE: automatic sketch generation method includes performing smoothing an original colour image; calculating the difference between the filtered image and the original colour image; calculating a negative of the obtained difference; calculating the sum of the original colour image with itself; calculating half the sum of the result and the negative of the difference between the filtered image and the original colour image; converting the obtained image into a halftone image of the original sketch; presentation thereof in matrix form; forming, based on the original sketch, a sequence of new sketches, for each of which three parameters of the change of face on the original sketch are generated, and a procedure for changing the matrix based on said parameters.

EFFECT: faster formation of an original sketch based on an original image and enabling automatic generation of the required sequence of new sketches for finished sketches.
