template matching using proximity measurement
This function matches the given template and returns all rects where the template is found with at least the given significance. The significance value must be specified in range [0,1] whereby significance levels lower then 0.5 involve as a rule too many results.
Template matching is performed by the following steps
![\[ BinaryMap(x,y) = \bigvee\limits_{channels\;\; c} ProximityMap(x,y,c) > significance*255 \]](form_148.png)
I applied some exemplary Benchmarks on a 2GHz Core2Duo with the following results:
The internally used Ipp-Function uses several Threads to apply the proximity measurement call, which means that the function might become much slower on a single core machine.
| src | source image where the template should be found in |
| templ | template to search int the src image |
| significance | significance level in range [0,1] (common values are 0.8 to 0.95) |
| buffer | temporary image buffer (this buffer can be given to the function optionally) if given this buffer is exploited internally. The buffers size and channel count |
| clipBuffersToROI | are adapted automatically |
| rd | Optionally exploited ImgRegionDetector object pointer. If given, this region detector is used, which can speed up Performance in successive calls to matchTemplate |
