Development of High Data Capacity Color Code

Abstract

This paper presents the implementation of high data capacity code by embedding multiple colors into the code. The main intention of this project is to implement a code that consists at least double the data capacity as compared to the present Quick Response (QR) code. This paper explains the elements that consist in the proposed high data capacity code layout. The high data capacity code utilizes color multiplexing technique to represent data by using 8 kinds of colors. The colors involved are three primary colors, three secondary colors, black and white. Besides, the code is embedded with same error correction algorithm as QR code namely Reed Solomon Error Correction. In this project, a decoder application is developed on personal computer to decode the information from the camera-captured code. The results show that the developed decoder software is capable to perform decoding without any error within the captured range of 7 cm to 15 cm. Since the developed second prototype consist of similar number of module with QR Version 8, the performance is assessed to compare with QR Version 8. As outcome of this project, the developed high data capacity code is to achieve more than doubles the data capacity of QR code Version 8.
