Detailed Description
Matches model seismic traces with input cube traces.
The idea is that you provide a set of N small traces, against which a (part of) traces from real data are matched. Optionally, you can provide a 'thickness' of each model (in trace Z position units, usually time). The model trace must have a 'pick' in the info(), which serves as the center of the model trace.
Model scores (correlations or similarities) at a Z position can be checked against a cutoff value. If the score is higher than the cutoff, we have a 'hit'.
Normal mode: The models slide along the input trace and give a score value at each sample position. Thus, at each sample position, we get N matches. Then, these matches are processed. Three output traces are available, which contain, for each sample:
- Scoretrace: The sum of all score values (correlations) of the hit models
- Hit trace: the number of hits at this position
- Winner trace: the best matching model number.
Horizon mode: Now, the match is along a horizon only. Thus, at every position there is a single score i.e. the score, hit and winner traces have only one value.
