Curvelet变换在位场数据去噪中的应用

摘要

为了解Curvelet变换在位场数据去噪处理中的效果，从Curvelet 变换的原理着手，通过对多矩形棱柱体模型进行Curvelet变换去噪和普遍应用的小波阈值去噪试验对比，验证了Curvelet变换去噪的有效性问题。将其应用于实测位场数据的处理中，取得了较好的效果。理论和实测数据的处理结果都表明， Curvelet变换在位场数据的去噪处理中是可行有效的。%In order to understand the effect of Curvelet transform denoising in potential field data processing , the study started from the principle of Curvelet transform , through contrasting the experiment between Curvelet transform denoising and wavelet threshold denoising used in general for the multiple rectangular prism model , the validity of the Curvelet transform denoising was verified .It is applied in the measurement of potential field data pro-cessing , and the good results have been achieved .Theory and the measured data processing results show that the Curvelet transform denoising is feasible and effective in potential field data processing .
