It is difficult to acquire deep seismic reflection profiles on land using the standard oil-industry acquisition parameters. This is especially true over much of Tibetan plateau not only because of severe topography and rapid variation of both velocity

将二维双树复小波变换(DT-CWT)与非抽样方向滤波器组(NSDFB)相结合,构造一种新的非抽样复轮廓波变换(NSCCT),并对其平移不变性作了相应证明。同时利用对称的正态逆高斯(NIG)分布先验概率模型和贝叶斯最小均方算法,提出一种基于NSCCT的图像去噪算法。实验结果表明,本文构造的NSCCT能够有效地抑制伪Gibbs现象,并且具有更丰富的方向分量,因而在图像的细节和纹理表现方面有一定的优势。

提出了一种图像去噪方法,将高斯尺度混合(GSM)模型引入非下采样Contourlet变换(NSCT)域,构造了基于NSCT分解系数的邻域模型,并利用Bayes最小均方(BLS)估计进行局部去噪。仿真实验结果表明,通过本文提出的方法能够有效去除高斯噪声,较完整地保持图像中的边缘等细节信息,在峰值信噪比(PSNR)提高与视觉效果上优于其它的去噪方法。实验结果验证了方法的正确性。
