# Template match with gray model(ncc)

## rotate-model vs main branch


| method    | main(ms) | rotate-model(ms) | factor(main/rotate-model) |
|-----------|----------|------------------|---------------------------|
| train     | 1        | 680              | 1/680                     |     
| match     | 31       | 16               | 2                         |
| train-omp | 1        | 160              | 1/160                     |
| match-omp | 12       | 6                | 2                         |

result: main brain method train model really fast(1ms) and parameter free, rotate-model method 2x faster in matching.
