Abstract: A method and system for determining an optical waveform based on a plurality of print features of a selected marking of a document. The method and system comprise obtaining optical image data representing the print features of the selected marking. The optical image data is corrected for at least one of print contrast or reflectance of the print features in the optical image data using respective print contrast thresholds or reflectance thresholds to produce a converted pixel map of the selected marking, the pixel map containing an ordered sequence of values. Also included is a generation module to transform the print features represented in the converted pixel map to a plurality of corresponding waveform features to produce the optical waveform of the selected marking, the corresponding waveform features including a plurality of spaced apart peaks representing respective optical signal levels of the print features.

Abstract: A plurality of PCS values are determined for a document having an area of interest containing critical data and a background image. Reflectance values distributed across the document are obtained and PCS threshold values corresponding to a plurality of locations on the document are stored in memory. Respective PCS values of a plurality of target portions of the surface are determined, each respective PCS value based on a reflectance value of the corresponding target portion and a reflectance value of a corresponding region located adjacent to the target portion, each of the regions being different for each target portion, each PCS value assigned a location representative of the location of the target portion, the size of the region being greater than the size of the target portion. The stored PCS threshold values are compared with the calculated PCS values to determine the acceptability of the background image.

Abstract: The method provides a visualization technique for rendering multidimensional data points as 2D curves on a 3D plot with the third dimension representing their order in the multidimensional data set. The technique uses colour palettes to render individual data curves, which enables visual analysis of the entire dataset based on the colour characteristics of the resulting image. The method also suggests a technique for: a) visualizing a distance between multidimensional data points; c) showing a linear segment between two multidimensional data points; d) displaying a colour map of an individual multidimensional point or data set; e) displaying a multidimensional data interval.
