by constructing a volume of spatio-temporal data in which consecutive images are stacked to form a third, temporal dimension (figure 1). The benefits of analysing this volume are realised when the images are sampled sufficiently often such that there is continuity in both temporal and spatial domains. One of the major advantages of this

Perdurantism or perdurance theory is a philosophical theory of persistence and identity. [1] The debate over persistence currently involves three competing theories—one three-dimensionalist theory called "endurantism" and two four-dimensionalist theories called "perdurantism" and "exdurantism". For a perdurantist, all objects are considered ...

Is it a metaphysically sufficient condition for the persistence of an object? Obviously not; a tree can burn until it is just a pile of ash, though there were no leaps through space or time.
