Designing a 2D color barcode

The barcode technology has undergone many dramatic changes during the past few years. This is due to the increased need for encoding more data into the barcode. One of the latest developments in the barcode technology is color barcode, developed by Microsoft´s High Capacity Color Barcode (HCCB). With four or eight colors, color barcodes are now used extensively in certain areas such as airports, print advertising and mobile phones compared to the 2D black and white barcodes such as Quick Response (QR) code and data matrix. This paper provides an overview of six papers related to color barcode and later introduces an algorithm developed to encode data using binarization and grouping of bits to form a color barcode and also to decode data from color barcode.
