  • analyzing RGB scan data for determining an approximate location of a background in the scan data representing a background adjacent a document having a similar color as the background;

    setting a threshold for at least one of R, G, and B, the threshold being based in part on RGB values of the background and a predefined color threshold;

    setting an intensity threshold;

    analyzing the scan data using the thresholds for generating distribution points;

    detecting a first edge of the document based on a location of a contour in the distribution points; and

    outputting the scan data and information about the detected edge.
