Description: 本程式实做了Noise Reductin Algorithm
2005年一个韩国人在ieee发表的Paper
Block-based noise estimation using adaptive Gaussian filtering
此论文也收录在资料夹中，供使用者参考。
首先，click open file，
选择第一张原始图(未被杂讯污染)
接下来选择第二张图(有杂讯)
你可以直接点选Noise Reduction观看结果
也可以先调整旁边的threshold，观看不同threshold下去除杂讯的效果。
本程式利用统计理论，在去除杂讯的过程，成功保留了边缘特征，
使影像看起来较为立体、清晰。-This program is to do a Noise Reductin Algorithm2005 a Korean in the year ieee published PaperBlock-based noise estimation using adaptive Gaussian filtering of this thesis is also included in the folder for reference. First of all, click open file, select first the original plan (not noise pollution) Next select the second graph (with noise) you can watch the results of Click Noise Reduction can also adjust next threshold, watch different under the threshold to remove noise effects. This program using statistical theory, to remove noise in the process of successfully retained the edge features, to make images look more three-dimensional and clear. Platform: |

Description: 提出一种有效的语音增强算法，该算法使用重叠相加FF-r滤波器进行谱幅度估计，给出噪声估计的两个均值参数，此参数适用于任何噪声．而且进行噪声估计无需检测语音间隙，无需VAD的运算过程，克服了单信道噪声
压缩算法的缺点．-An effective speech enhancement algorithm using the overlap-add FF-r filter in spectral amplitude estimation, given the noise mean estimate two parameters, this parameter applies to any noise. And no detection of speech to noise estimation space, without VAD computing process, overcome the single-channel noise suppression algorithm shortcomings. Platform: |

Description: duction techniques proposed in the art are expressed as a spectral
gain depending on the a priori SNR. In the well-known decision-
directed approach, the a priori SNR depends on the speech spec-
trum estimation in the previous frame. As a consequence the gain
function matches the previous frame rather than the current one
which degrades the noise reduction performance. We propose a
new method called Two-Step Noise Reduction (TSNR) technique
which solves this problem while maintaining the benefi ts of the
decision-directed approach. This method is analyzed and results
in voice communication and speech recognition context are given.-noise estimate Platform: |
