这篇是96年的水印论文，全英文版，中文题目：一种安全强大的扩频水印技术(This is a 96-year watermark papers, all in English, Chinese subjects: a safe and powerful Spread Spectrum Watermarking)

一种新颖的退化图像复原算法。结合最大差值先验假设和最大局部对比度先验假设，快速有效的得到退化图像的深度转换估计图。结合软抠图法和shades of the gray算法实现图像去雾和水下图像处理。(A novel degraded image restoration algorithm. Combined with maximum difference between a priori assumptions and maximum local contrast priori hypotheses, quickly and efficiently get degraded image depth conversion estimates Chart. Combined with soft matting law and shades of the gray image algorithm to image processing and underwater fog)
