COMBINING A QR CODE AND AN IMAGE

摘要

A QR code is combined with a base image, preserving useful functionalities of both the base image and the QR code. For example, the base image remains clearly visible and recognizable by humans; the transparent QR code remains readable by scanners; machine image search can distinguish the base image from the combined image; and faces of the combined image are usable by machine face recognition programs. A QR code is generated with transparencies for different regions. An inner portion and outer shell portion for each module each may have different transparencies. Inner portion size relative to outer shell size is selectively adjustable. The generated QR code image may be combined with a given base image such as a face or company logo using the transparency values of the QR code image to make the two images appear as overlaid on one another with varying degrees of transparency.

1. A system comprising:
a non-transitory memory; and one or more hardware processors coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the system to perform operations comprising:
generating a QR code comprising plurality of modules, each module comprising at least one pixel;dividing the plurality of modules of the QR code among a plurality of regions, a first region of the plurality of regions comprising a square of a position pattern or an alignment pattern, the square being rounded according to a roundness value;setting a first transparency value for at least one pixel contained in the modules of the first region;setting a second transparency value for at least one pixel contained in the modules of a second region; andcombining the QR code and an image pixel-by-pixel using alpha-compositing based on the transparency values set for at least one pixel contained in the modules of the first region and the second region.
