Wrapping based curvelet transform is faster in computation time and more robust than ridgelet
and USFFT based curvelet transform.
Typical methods of watermarking were based on Discrete Curvelet Transform DCUT , DWT , DFT , spatial-domain schemes , Ridgelet
transform [8, 9], and curvelet transform .
in computerised tomography [18, 32, 34, 29, 28], for fast summation algorithms [35, 36, 23], for moving least squares approximation , as fast Fourier transform on the sphere , or as part of the ridgelet
and curvelet transforms [27, 6].

anteriorly and laterally.
In one type the upper surface of the scale crown is smooth and flat, and lateral ridges occur as fine longitudinal ridgelets
beneath the crown plate.

, lifting wavelets, etc
The scales are very small to small, mushroom-shaped, without any visible sculpture on the crown surface but with a relatively high neck that occasionally carries vertical ridgelets
Posterior spines are covered with oblique ridgelets
