Abstract
Summary
This paper presents an algorithm based on special case of Coppens’ method for automatic first break picking and its quality control using median filter. The algorithm works in two steps; in the first step, the algorithm picks up the first break and in the second step, it refines the bad picks with the help of a median filter. Once all the bad picks are identified, their first breaks are searched within a smaller window. The entire process is automated and faster than Coppens’ technique, hence minimum human intervention is required without compromising the quality of the first break picks.
