DENOISING METHOD BASED ON WAVELET PACKET AND FORWARD-BACKWARD PREDICTION IN F-X DOMAIN
【摘要】 小波包变换具有分时分频的特性,是非平稳信号分析处理的一个很好的工具本文将小波包的分时分频特性结合地震信号处理中的F—X域预测抑制噪声技术,提出了小波包F—X城前后向预测去噪方法实际应用结果表明,该方法对于叠后地震剖面的随机噪声抑制比较好,有很强的实用性
【Abstract】 Possessing the capability of time-frequency localization, the wavelet Packet is a useful tool in the analysis of non-stationary signals. A new denoising method based on wavelet packet and forward-backward prediction in F-X domain is proal, which combines the denoising technology of prediction in F-X domain with the property of wavelet packet centralizing in local time-frequency domain. Practical application results show that this method is very efficient for random noise suppression in opt-stack profile.
