Abstract
We show multiple uses of space-time Fourier analysis in segmenting particular "activities" from sequences of images. Examples of such analysis include the detection and characterization or mitigation of scintillations, harmonic motion, and transverse motions of objects. Characterizations can include the estimation of parameters such as oscillation frequencies and distances and velocities of moving objects. We make use of stereo and time sequence imaging to generate scene data of higher spatio-temporal dimension than two. We demonstrate purely digital as well as hybrid digital/optical (correlator) implementations and discuss techniques for mappings between space and time in utilizing imaging and optical resources.
