一种具有理想对比度的可视密码方案
|
摘要
论文针对可视密码中像素扩展大、对比度低的特点,提出了一种具有理想对比度的可视密码方案,该方案基于完美的黑度可视密码方案(PBVCS),算法简单可行,易于操作,且实现了重构图像与原图像的一致性,没有像素扩展。
A perfect contrast visual cryptography scheme is proposed for the features of the large pixel-expansion and low contrast in VC.The scheme is based on both the perfect black visual cryptography scheme(PBVCS),keeping the consistency between the reconstructed image and the original image without pixel expansion.And this algorithm is simple and feasible,easy to operate.
