  • Abstract
    In this paper, we present a low complexity Modulo-PCM based coding algorithm for high speed video cameras used in applications that demand very high frame rates. By compressing the raw digital video generated at the camera front-end, our algorithm reduces the high data transfer speed required in this type of cameras. At the encoder, our algorithm compress the raw digital video by selectively removing bits. At the decoder, the spatial correlation between pixels is taken into account in order to achieve an efficient decoding. Experimental results show that our algorithm achieves significant improvements with respect to the simple strategy of dropping the same number of bits in all the pixels when high rate reductions are necessary or when the spatial correlation of the frames is high.
