摘要： A method for obtaining bitonal image data from a document obtains scanned color image data from at least two color channels and identifies, in the scanned color image data, at least one region of interest (R1) containing foreground content and background content. At least one threshold data value is obtained according to an image attribute that differs between the foreground content and the background content within the region of interest (R1). The scanned color image data of the document is converted to bitonal image data according to the at least one threshold data value obtained from the region of interest (R1).

摘要： The present invention relates to a method of aligning comprising providing a support, applying a transparent layer, patterning at least the transparent layer to produce a pattern and an alignment feature capable of scattering light, illuminating the support and the transparent layer with oblique lighting, providing an analysis system capable of sensing scattered light from the alignment feature and referencing, sensing the scattered light from the alignment feature; referencing the scattered light from the alignment feature to a position on said support; and aligning a second operation to the position.
