Automatic picking velocity by the viterbi algorithm for the complex geological case
Niantian Lin · Progress in geophysics · 2004
For the complex geological case, the velocity calculated, generally, covers some false information, such as velocity abnormity, because of variety of factor. Therefore, it is very important to acquire the correct the stacking velocity from the velocity spectrum, which calculated by the function of semblance object. In this paper, we introduce the Viterbi algorithm and apply it to auto pick the stack velocity. Here, the Viterbi algorithm makes the rule to integral the max velocity spectrum (energy group) forward and to get the optimal solution in recursion backward.
