First-Arrival Travel Times Picking through Sliding Windows and Fuzzy C-Means

Lei Gao, Zhen-yun Jiang, Fan Min
2019 Mathematics  
First-arrival picking is a critical step in seismic data processing. This paper proposes the first-arrival picking through sliding windows and fuzzy c-means (FPSF) algorithm with two stages.  ...  The second stage obtains the first-arrival travel times from the range using fuzzy c-means coupled with particle swarm optimization.  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...
