Discrete Wavelet Analysis for Fast Optic Flow Computation

  title={Discrete Wavelet Analysis for Fast Optic Flow Computation},
  author={Christophe P. Bernard},
This paper describes a new way to compute the optic flow, based on a discrete wavelet basis analysis. The optic flow is estimated locally by the projection of the di fferential optic flow equation onto wavelets. The resulting linear systems are small and of fixed size (3-5 e quations). They are solved to find out the visual displacement. In this way, we circumvent the classical prob lems of time aliasing and aperture. Moreover, the coefficients of the systems can be computed with a set of wa… CONTINUE READING
