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-space
Useful tools
fdct_usfft_dispcoef.m -- returns a matrix contains all curvelet coefficients
fdct_usfft_pos2idx.m -- for fixed scale and fixed direction, returns
the curvelet which is closest to a certain point on the image
Demos
fdct_usfft_demo_basic.m -- display the shape of a curvelet
fdct_usfft_demo_recon.m -- partial reconstruction using curvelet
fdct_usfft_demo_disp.m -- display all the curvelet coefficients of an image
fdct_usfft_demo_denoise.m -- image denoising using curvelet

提出了利用精密單點定位(precise point positioning,PPP)技術進行海嘯預警的方法,并利用TriP軟件對實測浮標數據進行了處理,將得出的海面高數據和海嘯波模型疊加進行了模擬分析。仿真結果表明,利用精密單點定位技術進行海嘯預警,能夠監測判斷海嘯的發生,并獲得海嘯波到達海岸的波高和時間,提供一定的預警信息。
