PSF
- 本文针对灰度图像的盲复原问题进行了一些研究,介绍了两种不同的图像盲复 原处理的方法。一种是误差一参数分析法,该方法适合于辨识可以用参数来表征的 点扩散函数,如线性移动模型和Gauss模型等,然后根据估计的参数确定退化图像 的点扩’散函数,再利用常规的复原算法(如维纳滤波法)对退化图像进行复原处理 另一种是非负支撑域约束递归逆滤波(NAS-R工F)算法,文中介绍了NAS-R工F算法 的基本思想,并结合正则化的思想,提出了NAS-RIF的改进算法,相应对该算法的 性能效果

- 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 : T

SSSS
- 通过建立运动模糊数学模型, 进行了消除运动模糊的仿真实验, 维纳滤波恢复运动模糊图像效果较 好。在图像恢复技术中, 点扩展函数( PSF) 是影响图像恢复结果的关键因素, 所以常常利用先验知识和后验判 断方法估计PSF函数来恢复图像。实验表明在实际恢复过程中如果运动模糊图像混入了噪声, 必须考虑到信噪 比、噪声的自相关函数和原始图像的自相关函数对恢复后图像的影响。-Through the establishment of mathematical model of motion
