VIDEO RESTORATION ON A MULTIPLE TMS320C40 SYSTEMThis document describes a parallel video restoration system for restoring old motion picture archives. A Gaussian-weighted, bi-directional 3-D auto-regressive (B3D-AR) algorithm is used to alleviate the presence of noise. The equations implemented by the system are presented. Parallel implementation and load balancing on an array of fifteen TMS320C40 parallel floating-point digital signal processors (DSPs) are discussed. Photographs are shown of results from artificially and naturally degraded sequences. A list of references is included. This application is the winner of the 1995 TI DSP Solutions Challenge, a contest for university design projects.
