An efficient and robust method for automatic first arrival picking using under-sampled fast high-resolution radon transform

Automatic picking using coherence measurement and global optimization

“…Hatherly (1982) introduced statistical-based methods to pick first arrivals and Song et al (2013) used a multi-time energy ratio windowing to pick primary events. Latif and Mousa (2016) used the radon transform to perform an automatic picking increasing the Copper´s method. Furthermore, energybased methods became frequently used (Spagnolini, 1991;Coppens, 1985;Murat and Rudman, 1992) together with fraction dimension analysis and wavelet transform (Boschetii, 1996;Tibuleac et al, 2003).…”
