A New Data Transfer Method via Signal-Rich-Art Code Images Captured by Mobile Devices
Abstract— A New Data Transfer Method via Signal-Rich-Art Code Images Captured by Mobile Devices. A new type of signal-rich-art image for applications of data transfer, called signal-rich-art code image, is proposed. The created code image is visually similar to a preselected target image and, with a given message embedded, achieves the effect of the so-called signal-rich art. With its function similar to that of a QR code, such a type of image is produced by encoding the message into a binary bit stream, representing the bits by binary code patterns of 2 × 2 blocks, and injecting the patterns into the target image by a novel image-block < Final Year Projects 2016 > modulation scheme. Each signal-rich-art code image may be printed or displayed and then is recaptured using a mobile device camera.
