Abstract:
1. A method for parameterization of incremental patterns, comprising the steps of: configuring a computer system to perform parameterization of incremental patterns, and entering an image of a 2-D incremental pattern (IP) under study into said computer system; (a) processing, in said computer system, said image of the IP under study to acquire a binary initial image of an incremental pattern under study in a predetermined format, said incremental pattern (IP) under study containing growth incremental bands (IB) and secondary lines, wherein said binary initial image is formed with a plurality of first cells and a plurality of second cells, said first cells forming a front of at least one of said incremental bands; (b) filtering, in said computer system, said binary initial image to remove said secondary lines therefrom, thereby forming a filtered initial binary image of said incremental pattern under study; (c) plotting, in said computer system, a plurality of transects onto said filtered initial binary image, each of said plurality of transects extending from a respective initial point towards the periphery of said filtered initial binary image in crossing relationship with at least one of said incremental bands at a specific angle (α (d) applying, through said computer systems, a segmentation and labeling procedure to said filtered initial binary image to convert said filtered initial binary image into an n-partite graph G(n) describing an anisotropic structure of said incremental pattern under study in a 2-D domain, wherein said segmentation and labeling procedure is applied between neighboring transects in each pair thereof, resulting in a set of bi-partite graphs G (e) constructing, in said computer system, a 2-D model of said incremental pattern under study through the steps of: calculating a width of each of said incremental band along each of said plurality of transects across the 2-D plane of said incremental pattern under study, calculating said angle α calculating an area of said each incremental band contained between neighboring transects of said plurality thereof across the 2-D plane of said incremental pattern under study based on the equal distance (in pixels) between all pairs of the neighboring transects across said 2-D plane of said IP under study, and processing said n-partite graph G(n) to reduce noise in the width and area of said incremental bands calculated across the 2-D plane of said incremental pattern under study; (f) calculating, in said computer system, an average width and average area of incremental bands based on said width and area of said as each incremental band; (g) calculating, in said computer system, a structure of incremental bands; and outputting results of calculation at an output of said computer system.
