METHOD AND SYSTEM FOR DETERMINING EXPANDED CONTOURS ON DIGITAL IMAGES Russian patent published in 2017 - IPC G06T1/00 G06T7/181 G06K9/46 

FIELD: physics.

SUBSTANCE: image processing subsystem includes: a separate hardware layer or hardware layer used in conjunction with devices, tools or systems, including one or more processors and one or more memory modules; and instructions stored in one or more physical storage devices that, when executed by one or more of the processors, control the image processing subsystem to: acquire a digital image, and apply multiple parameter values controlling contour determination by determining the seed pixels within the digital image coinciding with brightness boundaries, and for each of the plurality of seed pixels, an initial contour construction that includes a seed pixel, an iterative extension of both ends of the initial contour along the brightness border to create the detected contour and to preserve the detected contour in a data structure in memory.

EFFECT: ensuring the definition of curvilinear and rectilinear contours on digital images.
