NTIA Handbook HB-06-441aBatch Video Quality Metric (BVQM) User’s ManualDecember 2006Mark A. McFarland, Margaret H. Pinson, Stephen Wolf |

| Abstract:
This handbook provides a user’s manual for the batch video quality metric (BVQM) tool. BVQM runs under the Windows
XP® operating system. BVQM performs objective automated quality assessments of processed video clip batches (i.e., as
output by a video system under test). BVQM reports video calibration and quality metric results such as: temporal
registration, spatial registration, spatial scaling, valid region, gain/level offset, and objective video quality
estimates. BVQM operates on original and processed video files only, and has no video capture capability.
BVQM compares the original video clip to the processed video clip and reports quality estimates on a scale from zero to one. On this scale, zero means that no impairment is visible and one means that the video clip has reached the maximum impairment level (excursions beyond one are possible for extremely impaired video sequences). |
