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.

主权项

1. A system comprising:
a processor; and a data storage device including a computer-readable medium having computer readable code for instructing the processor that, when executed by the processor, causes the processor to perform operations comprising:
generating a QR code comprising plurality of modules, each module containing at least one of a plurality of pixels;dividing the plurality of modules of the QR code among a plurality of regions;for modules of a first region, setting a first transparency value for pixels contained in those modules;for modules of a second region, dividing each module into an inner portion and an outer shell portion, setting a second transparency value for pixels contained in the inner portion, and setting a third transparency value for pixels contained in the outer shell portion; andcombining the QR code and an image pixel-by-pixel using alpha-compositing according to the transparency value set for each pixel.
