Evaluation of Video Compression Methods for Network Transmission on Diverse Data: A Case Study
Abstract
There is a variety of video compression methods proposed in the
literature. Choosing the best method for a specific type of video
can involve a lot of experimentation and trial-and-error. This paper offers a quantitative evaluation of three popular compression
methods, namely HEVC, MJPEG, MJPEG2000. Our evaluation uses
five different types of video data that are commonly transmitted
over a network. We use two evaluation metrics, namely PSNR and
encoding time. While our evaluation is still preliminary, and will
eventually be expanded to include more compression methods,
larger datasets, and more metrics, it already includes features not
encountered in evaluations that have appeared in prior literature.
Even in its current form, to the best of our knowledge, our evaluation is the first one to evaluate both PSNR and encoding time,
of both inter-frame and intra-frame codecs, on both natural and
synthetic videos.
