The TemplateMatchingMethod defines the method that is used by the underlying template matching algorithm. For the formula used to calculate the similarity, see Object Detection - matchTemplate on the OpenCV website.
| Sqdiff | Square difference (CV-TM-SQDIFF). A lower value in the match result means a better match. |
|---|---|
| SqdiffNormed | Use normed square difference (CV_TM_SQDIFF_NORMED). A lower value in the match result means a better match. |
| Ccorr | Cross correlation (CV_TM_CCORR). A higher value in the match result means a better match. |
| CCorrnormed | Use normed cross correlation (CV_TM_CCORR_NORMED). A higher value in the match result means a better match. |
| CCoeff | Use CV_TM_CCOEFF. A higher value in the match result means a better match. |
| CCoeffNormed | Use CV_TM_CCOEFF_NORMED. A higher value in the match result means a better match. |
