    Remarks

    Corner mark is a search pattern ("L" pattern), which consists of two lines, of equal length, outgoing from one point at a right angle.

    Example

    This C#/VB.NET code shows how to identify a document image using algorithm that creates an image footprint based on L search patterns.
