摘要
在对传统的图像边缘检测的基础上,利用加入方向性的边缘检测滤波器进行去噪.该方法加强了对地震资料的地层纹理方向的滤波作用,使得地层沿层理方向的连续性得到一致性增强,并且保护了边缘信息.同时实验结果表明,该方法有效地消除了地震图像的噪声,提高了同相轴的连续性和地震资料的信噪比.
Based on the traditional image edge detection, the method of directional edge detection filters to de-noising is used. This process can strengthen the filter effect of the stratigraphic texture direction of the seismic data, enhance the continuity along by direction of bedding consistently, and protect the edge information. The experimental results also show that the new method can significantly reduce the noise in seismic： profile and improve the lineups continuity and SNR of seismic data.
