Paper Abstract

Four perceptually based metrics were compared for use in studies of video bandwidth compression in a military context. They include the National Imagery Interpretability Rating Scale (NIIRS), a task satisfaction confidence scale (TSC), an information conveyance scale (IC), and an artifact rating (AR) scale. The metrics were used in two compression studies using both MPEG-2 and frame decimation. The studies used video imagery collected with an unmanned aerial vehicle (UAV). The metrics were compared in terms of sensitivity and reliability. Results were also compared to those from other studies employing the ITU-R BT. 500-9 double-stimulus continuous quality-scale (DSCQS) in terms of both findings and metric performance. DSCQS is the metric commonly used in studies of bandwidth compression for commercial applications. It was concluded that for studies of video quality for military applications, NIIRS was the preferred perceptual metric. It was shown to be applicable to video, was comparable to DSCQS in reliability and sensitivity, and is a metric most familiar to the intelligence community.
