Claim Text:
1. A method of automatically identifying one or more digital representations of single- and/or few-layer thin-film material in a digital image, the digital image having a predetermined number of colour components, and the method comprising: determining a background colour component of the digital image for each colour component, and determining or estimating a colour component of thin-film material to be identified in the digital image for each colour component, the thin-film material to be identified having a given number of layers being at least one, wherein the determining or estimating a colour component of thin-film material to be identified in the digital image for each colour component comprises: obtaining a pre-determined contrast value for each colour component and determining or estimating the colour component of the thin-film material to be identified and having the given number of layers for each colour component by, for each colour component, multiplying a numerical difference between the pre-determined contrast value for a given colour component and about 1 with the background colour component for the given colour component, and wherein the method further comprises: identifying one or more digital representations of single- and/or few-layer thin-film material as points or parts of the digital image that, for each colour component, has a colour component being within a predetermined range of the determined or estimated colour component of the thin-film material to be identified having the given number of layers.
