Max no of matches - Use to limit the number of matches. Useful when only one object is searched or when the you know how many matches there are.

• Keep best matches for sorting - use the template with best score - when unchecked all accepted templates are used and the sort by results order is used before limiting the number of matches

Minimum distance between matches - This parameters is used to remove multiple matches of the same object. The value is normally defined by the object itself - it is impossible to get two matches closer than that.

Note : an implicit value is set by default, based on template size - you can here override that value - often used in OCR and OCV applications.

Intensity - Can be used to remove matches which has non-typical intensity values

Standard Deviation - Can be used to remove matches with non-typical standard deviation values

Match center position - useful to remove matches at the boundary of the roi

X position

• Min  - minimum x-coordinate of match

• Max - maximum y-coordinate of match

Y position
