Does imago have a centroid and or correlation tracker?
Yes IMAGO can offer a centroid or correlation algorithm. However these are names that were applied by Octec. IMAGO has developed a number of more advanced tracking techniques that that work better for backgrounds with any clutter. Correlation simply means shape and Centroid literally means centre of the target, in Octecs case it is the centre of the darkest or brightest part of the image. Hardware trackers are limited in the complexity of their tracking algorithms. The better ones use correlation tracking which works very well for well-resolved targets but does not work well for missile tracking at longer ranges when the missile becomes a point target. Less complex trackers use either some kind of grey scale thresholding (also known as centroid tracking), size filtering or edge detection. Each of these techniques has inherent shortcomings, such as locking onto the ejector motor, smoke or the illumination of the ground. The better trackers allow the operator to switch between these tech
