摘要
重点阐述了在对模拟地震图进行数字化处理过程中 ,利用图中水平线信息完成倾斜校正以及利用中值滤波增强信号。
In the process to transform analog seismogram into digital data by using computer scanners,the seismogram image is detrended according to slope of horizontal baselines on original records.A median filtering technology is used to further improve image quality and seismic waveforms are adaptively retrieved by an image segmentation method.The method for correcting slope and image segmentation technology are introduced.
