The technique of Phase Diversity (PD) is widely adopted to measure the wavefront error caused by atmosphere turbulence and system error. PD solves the Zernike coefficients of the wavefront by utilizing two images obtained with different defocus value. In this paper
we propose a method to restore the image and estimate the wavefront error of an imaging system. And we use present white noises to verify the robustness of the algorithm. We design an experiment system and implement it in our laboratory. The proposed algorithm is validated by computer simulations and experimental results. To use a broadband white object in experimental system a reasonable simplification for the system model is done. Our results show that the robustness against Gaussian white noises of the method is better then the case when the variance value is 0.03. The proposed method can be used as a wavefront sensor and restore the degradative images by photoelectric image system. 2010 SPIE.

In the procedure of computed radiography imaging
we should firstly get across the characters of kinds of noises and the relationship between the image signals and noises. Based on the specialties of computed radiography (CR) images and medical image processing
we have study the filtering methods for computed radiography images noises. On the base of analyzing computed radiography imaging system in detail
the author think that the major two noises are Gaussian white noise and Poisson noise. Then
the different relationship of between two kinds of noises and signal were studied completely. By considering both the characteristics of computed radiography images and the statistical features of wavelet transformed images
a multiscale image filtering algorithm
which based on two-state hidden markov model (HMM) and mixture Gaussian statistical model
has been used to decrease the Gaussian white noise in computed images. By using EM (Expectation Maximization) algorithm to estimate noise coefficients in each scale and obtain power spectrum matrix
then this carried through the syncretized two Filter that are IIR(infinite impulse response) Wiener Filter and HMM
according to scale size
and achieve the experiments as well as the comparison with other denoising methods were presented at last.
