目前基于小波变换的图像压缩方案比较普遍。而二维小波只是一维小波的张量积,基函数的支撑区域由区间扩展为正方形,只有有限个方向。Contourlet 变换是一种图像的多尺度几何分析工具,能够稀疏表
Abstract—The contourlet transform is a new two-dimensional extension of the wavelet transform using multiscale and dire...
Contourlet is a new approach in image transform. There have something better than Fourier and Wavalet transform.
基于Contourlet 变换对其高频系数进行统计分析,从理论和实验方面证明Contourlet 变换的高频系数符合广义高斯分布,采用极大似然估计的方法对Contourlet 变换系数的边缘分布和联合
