AUTOMATIC IDENTIFICATION OF SINGLE- AND/OR FEW-LAYER THIN-FILM MATERIAL

摘要

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 colour components, by—determining (304) a background colour component of the digital image (100) for each colour component, and—determining or estimating (306) a colour component of thin-film material to be identified in the digital image (100) for each colour component by obtaining a pre-determined contrast value (CR; CG; CB) for each colour component and multiplying the respective background colour component with a numerical difference between the pre-determined contrast value (CR; CG; CB) for a given colour component and about 1, —identifying points or parts of the image with all colour components being within a predetermined range of the determined or estimated colour component.

主权项

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.
