摘要：

A nonlinear spatio-temporal filter capable of significantly attenuating noise in image sequences without corrupting image details is presented. The characteristics of the filter are described, and the results of several simulations on real-world sequences are shown. A real-time implementation of the algorithm on a last generation DSP is also described. It is shown that, by suitably exploiting the computational capability of the DSP, it is possible to process CIF images at 10 frames/sec.
