【摘要】 脊波变换是在小波变换的基础上产生的特别适合于表示各向异性奇异性的多尺度方法。本文简述了脊波变换理论和曲波变换理论,并通过曲波变换方法进行图像增强处理的实验,结果显示脊波和曲波比小波更适合表示线状特征。更多还原

【Abstract】 Ridgelet transform is based on wavelet transform, it is especially fit for figuring multiscale method of anisotropic singularity.In this article,simply narrated ridgelet transform theory and curvelet transform theory.An experiment is carried out to proceed image enhancement in curvelet transform method and the result shows that ridgelet transform is much better than wavelet transform to figure linear character.更多还原
