Abstract

The present disclosure discloses methods and systems for extracting an infrared (IR) security mark from a document. The method includes receiving a document including the IR security mark. A portion of the document including the IR security mark is extracted and a color information is obtained, wherein the color information includes at least one of a foreground color information and an adjacent foreground color information. One or more portions of the extracted portion are analyzed based on the foreground color information, to generate a foreground image including one or more foreground portions. One or more portions adjacent to the one or more foreground portions in the extracted portion are analyzed based on the adjacent foreground color information, to generate an adjacent foreground image. The foreground image and the adjacent foreground image are processed to extract the IR security mark.
