中心区域可视二维条码的设计及编码方法

Design and encoding method of central region visual two-dimensional barcode

传统的二维条码不具有可视化意义,为了弥补传统二维条码外观的不足,设计了一种新型的可视二维条码。根据人类视觉选择性注意机制设计了由中心编码区域和周边编码区域组成的中心区域可视二维条码,明显提高了条码的整体信息容量。基于可视二维条码的模式编码方法,提出了面向模式编码的误差扩散方法,保持了载体图像的分辨率。实验结果表明,该条码不仅具有较好的视觉效果,而且具有较大的信息容量。

The conventional two-dimensional barcode has not visually significant appearance. In order to overcome such drawback of the conventional two-dimensional barcode, a novel visual two-dimensional is designed. According to the human visual selective attention mechanism, central region visual two-dimensional barcode is designed, which is composed of center encoding area and surround encoding area. The whole information capacity of the barcode is increased clearly. Based on the pattern encoding method of visual two-dimensional barcode, pattern encoding-oriented error diffusion is proposed to remain the base image resolution. Experimental results show that the generated barcode has not only better visual quality, but also larger capacity.
