Description: This paper proposes an adaptive threshold
estimation method for image denoising in the wavelet
domain based on the generalized Guassian
distribution (GGD) modeling of subband coefficients.
The proposed method called NormalShrink is
computationally more efficient and adaptive because
the parameters required for estimating the threshold
depend on subband data. Platform: |

Description: 提出了一种基于非下采样Contourlet 变换的自适应图像去噪方法 首先对噪声图像进行非下采样Contourlet 变换，得到各
个尺度各个方向子带的系数，再根据该系数的能量自适应地调整去噪阈值 实验表明，与Contourlet 多尺度阈值去噪 Contourlet 自
适应阈值去噪相比，该方法在保留图像边缘细节的同时，能提高图像的PSNR 值，减少了Gibbs 现象-A new adaptive method of image de-noising based on NonSubsampled Contourlet Transform （NSCT）is presented.Firstly，
the noisy image is decomposed into a set of multiscale and multidirectional frequency subbands by NSCT， and then the threshold
is adapted automatically according to the energy of subband coefficients.Compared with the multi-scale threshold using contourlet
transform and using adaptive threshold based on contourlet transform， the simulation results show that the performance of this
method is superior in PSNR， meanwhile it can maintain the image edge and reduce the Gibbs phenomen Platform: |

Description: Abstract— We propose a simple speech compression algorithm
using subband division and ADPCM (Adaptive Differential
Pulse Code Modulation) algorithm. Although speech data are
stored in a semiconductor memory device, its capacity and the
available network capacity are limited. Therefore, it is necessary compress the data as much as possible. The first is that the

Description: 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 .
