The large volume of the seismic data calls for automatic and objective picking. We introduce a new automatic first-break picker, which uses image segmentation technology based on the instantaneous traveltime. The improved method combines the advantages of the two methods and picks up first breaks automatically under the guidance of image edge. The test of this approach on synthetic model reveals its properties. Field seismic data show that the proposed method can effectively do the automatic first breaks picking．Presentation Date: Tuesday, October 16, 2018Start Time: 9:20:00 AMLocation: Poster Station 5Presentation Type: PosterKeywords: head waves, traveltime, edge detection, seismic attributes, signal processingPermalink: https://doi.org/10.1190/segam2018-2998274.1FiguresReferencesRelatedDetailsCited byMultitrace first-break picking using an integrated seismic and machine learning methodXudong Duan and Jie Zhang10 June 2020 | GEOPHYSICS, Vol. 85, No. 4 SEG Technical Program Expanded Abstracts 2018ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2018 Pages: 5520 publication data© 2018 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 27 Aug 2018 CITATION INFORMATION Fei Luo, Huazhong Wang, Chengliang Wu, Peng Xu, and Ruyi Zhang, (2018), "Automatic first-breaks picking algorithm under the constraint of image segmentation," SEG Technical Program Expanded Abstracts : 2762-2766. https://doi.org/10.1190/segam2018-2998274.1 Plain-Language Summary Keywordshead wavestraveltimeedge detectionseismic attributessignal processingPDF DownloadLoading ...
