Laplace
传统的短时谱估计语音增强算法通常假设语音谱分量相互独立,没有考虑语音谱分量间的相关性。针对这
一问题,该文提出一种新的基于多元Laplace分布模型的短时谱估计算法。首先,假设语音的离散余弦变换(DCT)
系数服从多元Laplace分布,以此利用谱分量间的相关性;在此基础上,利用多元随机矢量的高斯尺度混合模型表
示,推导得到语音DCT系数矢量的最小均方误差(MMSE)估计的解析表达式;并进一步推导了基于该分布模型的
语音存在概率,对最小均方误差估计子进行修正。实验结果表明,该算法在抑制背景噪声和减少语音失真等方面优
于传统的语音增强方法。(The spectral components of speech are usually assumed to be independent in traditional short-time
spectrum estimation, which is not the case in practice. Tosolve this problem, a new speech enhancement algorithm
with multivariate Laplace speech model is proposed in this paper. Firstly, the speech Discrete Cosine Transform
(DCT) coefficients are modeled by a multivariate Laplace distribution, so the correlations between speech spectral
components can be exploited. And then a Minimum-Mean-Square-Error (MMSE) estimator based on the proposed
model is derived using a Gaussian scale mixture representation of random vectors. Furthermore, the speech
presence uncertainty with the new model is derived to modify the MMSE estimator. Experimental results show
that the developed method has better noise suppression performance and lower speech distortion compared to the
traditional speech enhancement method. )

README.TXT (this file)
CLOUD_ARRAY.TIF is a synthetic test image. It contains a 5x5 pattern
of identical, regularly-spaced cartoon clouds. This represents
an ideal field of view in XY coordinates in order to study the
effect of scanner field of view distortion.
MODEL_LIDAR_AND_VALIDATE_TFORM.M is the MATLAB program. NOTE: This
is a function M-file with a number of subfunctions inside.
Refer to the comment lines for detailed explanation of how the
program works.(
Some images are geometrically distorted due to optics others due to
nonuniform or curvelinear scan coordinates. Such distortions can be
corrected using spatial transformations given the governing distortion
geometry. This program demonstrates how to correct for nonuniform
polar scan distortion using spatial transforms in MATLAB with the Image
Processing Toolbox 3.1.)

在虚拟仿真环境下进行了几种不同规格零件的抓取试验。在ADAMS中进行仿真试验设置,创建传感器及仿真脚本命令,对两种规格零件进行了抓取试验分析,进一步验证结构设计的正确性及合理性。(the capture of several parts with different specification test was carried out in a virtual simulation environment. To further verify the correctness and the reasonable of the structural design, in ADAMS simulation test, the crawled test and analysis was done for two specifications of parts with the creating of command script and sensor.)
