Implementation of Pi Code using QR Code by embedding 2D Image

Abstract

In 21st century, 2D barcodes are used very commercial. It has been mostly used to product advertisement contents and many other purposes. However, it can appears a 2D barcode pattern is often too obtrusive for integrating into an aesthetically designed advertisement. In this way, before the barcode is decoded, no human readable information is provided. This paper proposes a new picture-embedding 2D barcode, called PiCode, which overcome these two limitations by equipping a scannable 2D barcode with a picturesque appearance. PiCode is designed with mannerly both the perceptual quality of the embedded image and the decoding robustness of the encoded message. It compared with the existing beautified 2D barcodes show that PiCode achieves one of the best perceptual qualities for the embedded image, and maintains a better tradeoff between image quality and decoding robustness in various application conditions. PiCode has been implemented in the Android based on a system and some key building blocks have also been provided to Android and iOS platforms. It is practicality for real-world applications has been successfully demonstrated.
