This directory includes matlab interface of the curvelet transform using usfft. Basic functions fdct_usfft.m -- forward curvelet transform afdct_usfft.m -- adjoint curvelet transform ifdct_usfft.m -- inverse curvelet transform fdct_usfft_param.m -- returns the location of each curvelet in phase ...

使用curvelet变换对一幅图像变换，显示其系数图，再选取阈值进行重构，显示重构的图像。

在matlab环境下生成一个正方形中心嵌套一个圆，并利用curvelet变换显示出其各个子层的系数图，良好的体现了curvelet变换的各向异性的性质。

Abstract - A &#64258 exible multiscale and directional representation for images is proposed. The scheme combines directional &#64257 lter banks with the Laplacian pyramid to provides a sparse representation for two- dimensional piecewise smooth signals resembling images. The underlying expansion is ...
