We propose a complete study in order to give a number of recommendations for MPEG-x and MJPEG2000 coders for video surveillance application. This study aims to achieve low bitrates for the different coders but similar perceptual quality than a hardware one based on MJPEG at 5.6 Mbit/s. First, we propose a subjective test according to the ITU recommendations, the Double Stimulus Impairment Scale (DSIS) which measures the global sum of perceived degradation, as well as the Double Stimulus Continuous Quality Scale (DSCQS), which measures the visual impression for each video. Then, an objective study has been carried out. The three metrics used for this objective test are: Peak signal Noise Ratio (PSNR), the Universal Quality Index and a new metric that we have developed. Finally, a study of the correlation between the subjective and objective tests are performed in order to make some recommendations about the bitrate achieving similar quality.
