Abstract: There is described a method for touchless counting of substantially planar substrates, especially banknotes, which are stacked in the form of stacks of substrates, said method comprising the following steps: taking at least one sample image of a portion of a side of a stack of substrates, which sample image contains contrast information representing substrate edges that extend along substantially a first direction in the sample image; processing the contrast information representing the substrate edges within the sample image (10), which processing includes subjecting at least one area of interest (20) within the sample image (10) to anisotropic diffusion to produce a processed image containing a substantially coherent set of continuous lines representing the substrate edges; and counting the number of substrate edges in said processed image.

Abstract: There is described a method for checking the authenticity of security documents, in particular banknotes, wherein authentic security documents comprise security features (41-49; 30; 10; 51, 52) printed, applied or otherwise provided on the security documents, which security features comprise characteristic visual features intrinsic to the processes used for producing the security documents. The method comprises the steps of (i) acquiring a sample image (c 0 ) of at least one region of interest (R.o.l.) of the surface of a candidate document to be authenticated, which region of interest encompasses at least part of the security features, (ii) digitally processing the sample image (c 0 ) by performing a decomposition of the sample image (c 0 ) into at least one scale sub-space containing high resolution details (d 1 1 , d 1 2 , d 1 3 ,...) of the sample image (c 0 ) and extracting classifying features (σ 2 , C,...) from the scale sub-space, and (iii) deriving an authenticity rating of the candidate document based on the extracted classifying features (σ 2 , C,...).

Abstract: There is described a method for checking the authenticity of security documents, in particular banknotes, wherein authentic security documents comprise security features (41-49; 30; 10; 51, 52) printed, applied or otherwise provided on the security documents, which security features comprise characteristic visual features intrinsic to the processes used for producing the security documents. The method comprises the step of digitally processing a sample image of at least one region of interest (R. o. I.) of the surface of a candidate document to be authenticated, which region of interest encompasses at least part of the security features, the digital processing including performing a decomposition of the sample image by means of wavelet transform (WT) of the sample image. Such decomposition of the sample image is based on a wavelet packet transform (WPT) of the sample image, preferably a so-called two-dimensional shift invariant WPT (2D-SIWPT)
