Comparison of cinepak, intel, microsoft video and indeo codec for video compression

摘要

The file size and picture quality are factors to be considered for streaming,storage and transmitting videos over networks. This work compares Cinepak,Intel, Microsoft Video and Indeo Codec for video compression. The peak signalto noise ratio is used to compare the quality of such video compressed usingAVI codecs. The most widely used objective measurement by developers of videoprocessing systems is Peak Signal-to-Noise Ratio (PSNR). Peak Signal to NoiseRation is measured on a logarithmic scale and depends on the mean squared error(MSE) between an original and an impaired image or video, relative to (2n-1)2. Previous research done regarding assessing of video quality has been mainlyby the use of subjective methods, and there is still no standard method forobjective assessments. Although it has been considered that compression mightnot be significant in future as storage and transmission capabilities improve,but at low bandwidths compression makes communication possible.
