GGDimagedenoising
我按这篇文章做的，广义高斯分布及其在图像去噪中的应用，没有完全做出来，谁做出来了，分享一下( The statistics of imagewavelet coefficients is non2Gaussian and can be described by generalized Gaussian
distribution (GGD). The paper investigates the issues of GGD statisticalmodel for wavelet coefficients in a sub2
band and the corresponding parameters estimation . A Bayesian estimate based subband adaptive thresholding de2
noising algorithm is designed, and the performance of noise reduction of this algorithm, compared with other clas2
sicalwavelet thresholding denoising methods, is discussed according to simulation results .

All-optical-microwave-filters
我们提出了一种新的方法来实现全光
微波使用光纤布拉格光栅阵列滤波
相同的反射率。确定了过滤器攻丝系数
通过一个宽带光源的光谱分布和
光栅的中心波长。由于光纤布拉格
光栅有相同的反射率，其特征
高均匀度的光栅是可能的，从而简化了
光纤布拉格光栅的制作，降低了实现
错误。此外，该宽带光的光谱分布

(We propose a novel approach to realizing all-optical
microwave filtering using an array of fiber Bragg gratings with
identical reflectivities. The filter tapping coefficients are determined
by the spectrum profile of a broadband light source and
the central wavelengths of the gratings. Since the fiber Bragg
gratings have identical reflectivities, the characteristics of the
gratings with high uniformity are possible, which simplifies the
fiber Bragg grating fabrication and reduces the implementation
error. In addition, the spectrum profile of the broadband light
source can be controlled using an optical filter, which could be used
to control the filter coefficients to suppress the filter sidelobes. A
microwave filter using four fiber Bragg gratings is experimentally
implemented.)
