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.

人类天生就有一种探索周围环境的内在动力,作为年轻人,我和凯文·米特尼克(Kevin Mitnick)对这个世界有着无比的好奇心并渴望证明自己的能力。我们努力学习新事物、解决难题并赢得比赛,但同时这个世界又告诉我们一个行为规则――不要过于放任自己对探索自由的强烈渴望。可对于最大胆的科学家和企业家,还有像凯文·米特尼克这样的人来说,跟随内心的这种渴望会带来极大的兴奋,并使他们完成别人认为是无法做到的事情。
There is a human natural surroundings to explore the internal driving force, as a young man, me and Kevin Mitnick (Kevin Mitnick) of this world have a tremendous curiosity and eager to prove himself. We strive to learn new things, solve problems and win the game, but at the same time in the world told us that a code of conduct- not to be too laissez-faire freedom of their strong desire to explore. May be the most audacious scientists and entrepreneurs, as well as Kevin Mitnick such people, this desire to follow the heart will bring great excitement, and enable them to complete other people think is impossible to do事情.
