correlationImage
RasterImage object that references the image for which to search.
points
An array of LeadPoint structures. This array will be updated with the starting points for the correlated areas.
xStep
Step size in the X direction (along image width), in pixels. For best results, use 1. This parameter accepts only positive values.
yStep
Step size in the Y direction (along image height), in pixels. For best results, use 1. This parameter accepts only positive values.
threshold
Value that indicates the correlation threshold, which is a measure of association required to consider two areas to be correlated. If the correlation value between correlationImage and an area in the image to be searched (the Run method image) is less than the correlation threshold they are u ncorrelated. Valid values range from 0 (zero resemblance) to 100 (perfect resemblance).
Run the CorrelationCommand on an image.
