【Documents】 3 DL : 0: 摘要:为了提高图像复原算法的性能 ,提出了一种改进的奇异值分解法估计图像的点扩散函数。从图像的退化离散模型出发 ,对图像进行逐层分块奇异值分解 ,并自动选取奇异值重组阶数以减少噪声对估计的影响。利用理想图像奇异值向量平均能谱指数模型 ,估计点扩散函数奇异值向量的频谱 ,再反傅里叶变换得到其时域结果。实验结果表明 ,该方法能在不同信噪比情况下估计成像系统的点扩散函数 ,估计结果比原有估计方法有所提高 ,有望为图像复原算法的预处理提供一种有效的手段。-Abstract : To improve the performance of image restoration algorithms , a modified Singular Value De2 [ ] [ ] composition SVD method was proposed to estimate the Point Spread Function PSF of an imaging system. Using the discrete image degradation model , a block2based SVD filter scheme was applied for the image denoising with an automatically determined singular value rank. After the spectra of PSF singular vectors were estimated under an exponential model for the averaged spectra of un2degraded image singular vectors , the IFFT was used to get the time2domain estimation of the PSF. The experi2 mental results show that this proposed method can be applied to estimate the PSF of the imaging sys2 tem under a wide SNR range and its performance is better than the original method. It may be used as an effective method for the image preprocessing in image restoration problems. [ ] Key words: image restoration Point Spread Function PSF block2based Singular Value Decomposi2

【Special Effects】 113172210SVD DL : 0: SVD随着计算机网络的不断发展,多媒体信息的版权保护问题变得十分突出,已成为一个非常紧迫的议题。数字水印技术是实现版权保护的一种非常有效的方法,已经成为信息隐藏领域的一个热门方向。本文着重讨论了数字水印技术在数字图像中的应用,特别地,对于基于神经网络和SVD的自适应的数字水印技术进行了深入的研究与实验。首先比较全面地介绍了数字水印技术的发展历史、现状、基本模型、特征、分类、现有的主要的算法和应用,并对数字水印的发展前景做出了一个展望。接着阐述了神经网络和奇异值分解( SVD)的相关理论。利用图像分割法,提出了基于图像分割和SVD的数字水印算法。该算法将原始图像划分为许多不同的区域,对于不同的区域,分别采用同一区域块用统一的量化步长和同一区域用基于统计特性的自适应量化步长等两种形式对其进行分析。而且在用统一的量化步长时,我们分别就嵌入部分分别为图像的某一区域和各个区域进行讨论。水印的提取不需要原始图像,并受到密钥的控制,不知道密钥就无法正确恢复水印。利用神经网络和奇异值分解的特性,提出一种通过自适应量化处理将二值水印图像嵌入到原始图像中的新的盲水印算法。该算法首先对原始图像进行小波变换-SVD随着计算机网络的不断发展,多媒体信息的版权保护问题变得十分突出,已成为一个非常紧迫的议题。数字水印技术是实现版权保护的一种非常有效的方法,已经成为信息隐藏领域的一个热门方向。本文着重讨论了数字水印技术在数字图像中的应用,特别地,对于基于神经网络和SVD的自适应的数字水印技术进行了深入的研究与实验。首先比较全面地介绍了数字水印技术的发展历史、现状、基本模型、特征、分类、现有的主要的算法和应用,并对数字水印的发展前景做出了一个展望。接着阐述了神经网络和奇异值分解( SVD)的相关理论。利用图像分割法,提出了基于图像分割和SVD的数字水印算法。该算法将原始图像划分为许多不同的区域,对于不同的区域,分别采用同一区域块用统一的量化步长和同一区域用基于统计特性的自适应量化步长等两种形式对其进行分析。而且在用统一的量化步长时,我们分别就嵌入部分分别为图像的某一区域和各个区域进行讨论。水印的提取不需要原始图像,并受到密钥的控制,不知道密钥就无法正确恢复水印。利用神经网络和奇异值分解的特性,提出一种通过自适应量化处理将二值水印图像嵌入到原始图像中的新的盲水印算法。该算法首先对原始图像进行小波变换...
