correlationImage
RasterImage object that references the image(s) for which to search.
points
Array of 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).
