The spatio-temporal Fourier transform is usually applied to determine the velocity of an object from a series of standard light intensity frames. In this paper the technique is extended to also determine the object acceleration. Although this technique is useful in standard illumination conditions, we have applied it to experimental low-light-level images, which require a shorter processing time.
