1. A system for crack quantification, the system comprising: a storage device; a processing system connected to the storage device; and a program stored in the storage device, wherein execution of the program by the processor configures the system to perform functions, including functions to: (i) extract, from a binary crack map, a centerline of an extracted crack using a morphological thinning operation; (ii) determine a minimum area orientation as being equal to an orientational strip kernel having a width and a minimum correlation value from among a set of a plurality of orientational strip kernels when each is correlated with the binary crack map, wherein the minimum correlation value is the area of the crack bounded between strip edges; and (iii) for each centerline pixel, determine a measured thickness as the minimum correlation value divided by the width of the corresponding strip kernel.
