This report summarizes a 24 month investigation on video data reduction method applicable to RPVs. Areas investigated included interframe reduction, two-dimensional transform and hybrid coding using Walsh and Fourier transforms and DPCM coding, and adaptive techniques using Hadamard transforms. Included are numerous photographs of low altitude target runs showing the effects of channel errors and coding degradation. A bibliography of up to date references on image processing is also included.
