Cross correlation integral

WebCross-correlation can track objects that deform over time, but with obvious and significant qualifications that will not be discussed here. Cross-correlation can also easily track a feature that moves by a significant fraction of its own size across frames, whereas this amount of translation could put a snake outside of its basin of convergence. http://www.ceri.memphis.edu/~smalley/ESCI7355/Ch6_Linear_Systems_Conv.pdf
