A fast butterfly algorithm for generalized Radon transforms
fast butterfly algorithm generalized Radon transforms
2015/7/14
Generalized Radon transforms, such as the hyperbolic Radon transform, cannot be implemented as efficiently in the frequency domain as convolutions, thus limiting their use in seismic data processing. ...
具有一维小波变换的逆Radon变换
小波反演公式 卷积回投射方法
2007/12/11
该文得到具有一维小波Radon变换的小波逆公式,从该逆公式导出Radon变换的卷积回投射法建立了Radon变换小波逆公式与二维Radon变换卷积-回投射方法之间的渐近关系.

INVERSE RADON TRANSFORM WITH ONE-DIMENSIONAL WAVELET TRANSFORM
Radon transform wavelet tran
2007/12/10
In this paper, the wavelet inverse formula of Radon transform is obtained with onedimensional wavelet. The convolution back-projection method of Radon transform is derived from this inverse formula. ...
