   array<LeadPoint>^ points,

   int threshold
)

Parameters

points: Array of Leadtools.LeadPoint objects to be updated with the starting points of the correlated areas.
listIndex: Array of integers to be updated with the indices of the images that match correlated areas.
xStep: Step size in the X direction (along image width), in pixels. For best results, use 1.
yStep: Step size in the Y direction (along image height), in pixels. For best results, use 1.
threshold: Value that indicates the correlation threshold, which is a measure of the association necessary for two areas to be considered to be correlated. If the correlation value between an image in the list and an area in the reference image is less than the correlation threshold they are uncorrelated. Valid values range from 0 (zero resemblance) to 100 (perfect resemblance).
