摘要： There is described a method of detecting and processing spaced-apart two-dimensional markers (C) that are distributed over a surface (S) to be imaged by means of an image acquisition sensor (10). The method comprises the following steps, namely, (a) acquiring an image (I) of at least a portion of the surface (S) by means of the image acquisition sensor (10), which image (I) includes multiple ones of said two-dimensional markers (C), (b) segmenting the image (I) acquired at step (a) into multiple sub-areas each containing a single two-dimensional marker (C), and (c) subjecting one or more of the sub-areas that contain a two-dimensional marker (C) to further processing. Segmenting the image (I) at step (b) includes (b1) sampling the image (I) at a coarse sampling resolution lower than a resolution of the image (I) to retrieve statistical data indicative of a distribution of the two-dimensional markers (C) in the image (I) acquired at step (a). Segmenting (b) also includes (b2) processing the statistical data retrieved at step (b1) to identify expected intermediate areas (AB) separating the two-dimensional markers (C) and expected marker areas (AC) containing the two-dimensional markers (C). Segmenting (b) further includes (b3) generating a segmentation mask (MSEG) based on the identification of the expected intermediate areas (AB) and marker areas (AC) at step (b2). Lastly, segmenting (b) includes (b4) segmenting the image (I) acquired at step (a) into the multiple sub-areas based on the segmentation mask (MSEG) generated at step (b3).

摘要： There is described a process of signing documents comprising generating a document identification (DID) of a document to be signed by at least one signatory and encoding the document identification (DID) into one or more watermarks (WM; WM SA ; ...). A hard copy (DOC HC ) of the document to be signed incorporating the one or more watermark (WM; WM SA ; ...) is produced. The one or more watermarks (WM; WM SA ; ...) provided on the hard copy (DOC HC ) of the document is/are read using an optical reader device (ORD; 10) and the document identification ([DID] ENC ) encoded into the one or more watermarks (WM; WM SA ) read by the optical reader device (ORD; 10) is decoded. The hard copy (DOC HC ) of the document to be signed is associated to a corresponding digital copy (DOC DC ) of the document to be signed based on the decoded document identification ([DID] DEC ). Signing of the document by the at least one signatory is performed using a digital signing device (DSD; 10), and signatory information (K SIG ) unique to the at least one signatory using the digital signing device (DSD; 10) is obtained. Finally, a digital signature (SIG) of the digital copy (DOC DC ) of the document is generated based on the decoded document identification ([DID] DEC ) and the signatory information (K SIG ), following which the digital signature (SIG) is applied to a digitally signed copy (DOC SIG ) of the document.
