FastMatchTemplate
Performs a fast match template
Returns: true on success, false on failure
Parameters:
source - source image (where we are searching)
target - target image (what we are searching for)
foundPointsList - contains a list of the points where the target was found
confidencesList - contains a list of the confidence value (0-100) for each
found target
matchPercentage - the minimum required match score to consider the target
found
numMaxima - the maximum number of search locations to try before exiting
(i.e. when image is down-sampled and searched, we collect the
best numMaxima locations - those with the highest confidence -
and search the original image at these locations)
numDownPyrs - the number of times to down-sample the image (only increase
this number if your images are really large)
searchExpansion - The original source image is searched at the top locations
with +/- searchExpansion pixels in both the x and y
directions
