摘要： 融合信息隐藏与二维条码编译码技术，提出一种基于图像的可视二维条码设计。对图像进行块误差扩散，得到的半色调图像作为码图，将编码块嵌入置乱后的码图，反置乱使编码块分散在码图中。与以往提出的图像条码相比，该设计注重图像的可视性，可以表达图像信息。实验结果表明，该设计效果较好。

Abstract: Combining the data hiding and 2D barcode encoding and decoding technology, this paper presents a design of visual two dimensional barcode based on the image. Obtaining the code-image from the grayscale image with block error diffusion, embed the encoding-blocks in the scrambled code-image and finally anti-scrambling the code-image to make the encoding-blocks disperse in it. Comparing with the image barcode proposed, this design lays particular emphasis on the visual effect and can convey the information of images. Experimental result show that the design has better effect..

Key words: two dimensional barcode, block error-diffusion, Arnold transformation, template matching, SSDA algorithm
