A Survey on PiCode: Picture-Embedding 2D Barcode

Abstract

In this Review paper discusses about the last few years, conventional Two-Dimensional (2D) barcodes and some existing beautified QR codes. Quick Response (QR) code is widely used in many applications such as marketing, for industrial applications, retail applications, health care applications, manufacturing, and product tracking etc.This paper explains the basic concept of QR images, i.e. a recently proposed beautified QR code. We focus on revising preprocessing methods by proposing block division and source & channel coding methods. In the traditional decoding procedure decoding steps consist of image binarization, corner detection, perspective transformation and error correction. So the existing barcodes have some limitations, so the new picture-embedding 2D barcode system: Picode proposed. PiCode technology improves the aesthetic value of the picture embedded barcode. To preserve both the perceptual quality of the embedded image and the decoding robustness of the encoded message PiCode is designed with careful considerations. Advantage of using PiCode in advertisement business to link customers in a more interactive, interesting, and unique way. So the PiCode enable pictures/logo to be integrated with a 2D barcode to achieve enhanced visual appearance and high decoding reliability.
