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. WebFeb 21, 2024 · Cross correlation is a measure of similarity between two signals, where one signal is allowed to be time-shifted. In this sense, the correlation is not a single number, but a function of the time shift. We say, "these two signal have a …
