为在增强地震剖面图像时获取纹线的构造及层序信息，提出一种基于地震剖面图像纹线方向的地震图像增强算法。根据地震剖面纹线的方向性，设计一个Gabor滤波器族，用其对低频分量图进行滤波去噪。利用小波变换与Gabor滤波器族各自的优点，实现地震剖面图像纹线的增强，提高整体运算效率。仿真结果表明，该算法对地震剖面图像处理后，均方误差与峰值信噪比均有明显的改善。
為在增彊地震剖麵圖像時穫取紋線的構造及層序信息，提齣一種基于地震剖麵圖像紋線方嚮的地震圖像增彊算法。根據地震剖麵紋線的方嚮性，設計一箇Gabor濾波器族，用其對低頻分量圖進行濾波去譟。利用小波變換與Gabor濾波器族各自的優點，實現地震剖麵圖像紋線的增彊，提高整體運算效率。倣真結果錶明，該算法對地震剖麵圖像處理後，均方誤差與峰值信譟比均有明顯的改善。

To obtain the structure and sequence information of stripe lines accurately while enhancing the seismic profile image ,a seismic image enhancement algorithm was proposed based on the directions of stripe lines on seismic profile image .Based on the directionality of stripe lines on seismic profile image ,a Gabor filter bank was designed ,by which low frequency component figure was filtered and denoised .With the advantages of wavelet transform and Gabor filter bank ,the enhancement of stripe lines on seismic profile was realized ,which improved overall operational efficiency .The simulation results show that the mean square er‐ror and peak signal to noise ratio are improved obviously after the seismic profile image being processed using this algorithm .
