  • 摘要: 隨著移動終端和移動互聯(lián)網(wǎng)的發(fā)展,快速響應(QR)碼被廣泛運用于移動信息交互。但是,標準的 QR 碼是由均勻分布的黑色與白色模塊組成,外觀類似噪聲信號,缺乏視覺美感,限制了QR碼的應用。針對此問題,該文提出一種提高QR碼視覺效果的美化方法。該方法將給定的彩色圖像進行顯著性檢測和半色調處理,得到相應的顯著性矩陣和半色調圖像,然后根據(jù)半色調圖像上的網(wǎng)點分布,對QR碼的模塊分布進行優(yōu)化。為了提高優(yōu)化效率,該文提出一種顯著性加權隨機優(yōu)化算法,將優(yōu)化后的QR碼和半色調圖像進行融合,得到與半色調圖像最相似的半色調QR碼。在圖像渲染階段,該文提出一種基于二分搜索的色彩調整算法,得到具有色彩信息和視覺美感的彩色QR碼。實驗分析表明,該方法生成的QR碼不僅保留了與標準QR碼一樣的抗遮擋、快速解碼等特性,還有效地提升了視覺效果,具有很好的視覺吸引力。
