System and method for embedding machine-readable codes in a document background

摘要

A method and apparatus are disclosed for embedding a two-dimensional machine-readable code into the background of a document in an aesthetically pleasing manner. The objects (picture, graphics, text, etc.) in a document image are first segmented from the background. A location for embedding the barcode is determined. A texture image is created by replicating the barcode to a size that covers the entire image. A modulation index map is generated from the segmentation results. The original image is modulated to produce the output image based on the texture image and the modulation index map.

1. A method of embedding a barcode in a document image, comprising, by a processor:
receiving a data file comprising data representative of a document image; receiving a barcode file comprising data representative of a barcode; forming a segmented image by separating a background region of the document image from one or more foreground regions of the document image; generating a texture image comprising a plurality of copies of the barcode by replicating the barcode so that the texture image has a size that extends at least to a predetermined portion of the document image; generating a modulation index map from the segmented image; and generating an output image by combining the document image with the textured image based on the modulation index map.
