  • Patent number: 7684623
    Abstract: The disclosure describes pattern recognition detectors and software used to detect patterns in image streams. The detectors operate on streams of image data, making them suitable for detecting certain types of patterns in documents and images passed between processes and devices. For instance, the streaming mode detectors operate in printer drivers on streams of image data being passed to a printer. Also, the streaming mode detectors operate in scanner drivers on streams of image data being passed from a scanner. The disclosure describes pattern detectors for shapes with complex features as well as objects comprised of many smaller shapes. The disclosure also describes novel raster line and edge tracing pattern techniques.

  • Publication number: 20010040979
    Abstract: Watermark and pattern detection can be improved by compensating for artifacts introduced into an image by a printer and/or scanner through which the image has passed. With the present invention, prior to watermark or pattern detection, the image is filtered or modified to compensate for artifacts introduced by the printer and/or scanner. Some scanners automatically compensate for artifacts introduced by the scanner by using a calibrated tone map. The automatic compensation provides an image from which, a watermark can be easily read. However, generally the user is provided with an interface which can be used to change certain parameters such contrast and intensity. The changes made by the user change the compensation (i.e. the tone map) applied to the image. If the user changes the compensation applied to the image it can affect the ability to read the watermark.
