A system, method, and computer program product are provided for detecting an edge in scan data. In use, RGB scan data is analyzed 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. Additionally, a threshold is set for at least one of R, G and B, where the threshold is based in part on RGB values of the background and a predefined color threshold. Further, an intensity threshold is set. Further still, the scan data is analyzed using the thresholds for generating distribution points. Also, a first edge of the document is detected based on a location of a contour in the distribution points. In addition, the scan data and information about the detected edge are output.
