Description: 基于小波零树特性的视觉感知度模型的优化方案, 给出了两种水印算法: 一种算法嵌入的是高斯序列水印, 通过相关检测实现盲检测 另一种算法嵌入的是二值图像水印, 水印的提取是非盲提取。这两种算法在所有重要小波系数( 包括最低频系数) 中嵌入水印, 以达到最大化水印嵌入量的目的, 并结合感知度模型在水印的透明性和鲁棒性之间实现了较好的平衡, 对于常见的图像处理操作, 特别是对于JPEG 和小波压缩均有较好的鲁棒性。-based on wavelet zerotree visual perception characteristics of the model optimization program, and presents two watermarking algorithm : An algorithm is embedded watermark Gaussian sequence, through correlation detection achieve a blind detection algorithm embedded in the binary image watermark, the watermark extraction from non-blind. These two important algorithm in all wavelet coefficients (including most low-frequency coefficients) embedded watermark, to maximize embedding of purpose, and perceptual model with the watermark of transparency and robustness between a good balance, for common image processing, particularly for JPEG and wavelet compression has better robustness.

Description: A new blind adaptive multiuser detection scheme based on a hybrid of Kalman filter and
subspace estimation is proposed. It is shown that the detector can be expressed as an anchored
signal in the signal subspace and the coefficients can be estimated by the Kalman filter using only
the signature waveform and the timing of the desired user.-A new blind adaptive multiuser detection s cheme based on a hybrid of the Kalman filter and subs pace estimation is proposed.
