Abstract
One or more digital representations of single- (101) and/or few-layer (102) thin-film material are automatically identified robustly and reliably in a digital image (100), the digital image (100) having a predetermined number of color components, by—determining (304) a background color component of the digital image (100) for each color component, and—determining or estimating (306) a color component of thin-film material to be identified in the digital image (100) for each color component by obtaining a pre-determined contrast value (CR; CG; CB) for each color component and multiplying the respective background color component with a numerical difference between the pre-determined contrast value (CR; CG; CB) for a given color component and about 1,—identifying points or parts of the image with all color components being within a predetermined range of the determined or estimated color component.
