Objective Video Quality Testing

Picture Quality Evaluation Tools

Steps for Quantitative Picture Quality Assessment

  • Use a Preloaded Uncompressed Test Patterns or Load Your Own

  • Play the Test Pattern to any Digital or Analog Device-Under-Test (DUT)

  • Input any File or Record from the DUT's Output

  • Automatic Temporal and Spatial Alignment

  • Log & Graph the Sarnoff JND Results

  • Subjectively View 2 HD Video Sequences to Verify Score

Tools to Help You Every Step of the Way

ClearView objectively scores the video quality using the Human Visual System (HVS) tool known as Just Noticeable Differences (JND). JND algorithmically predicts the video quality based on modeling hundreds of expert viewers, and ranking their score based on viewing distance, perceived artifacts, viewing angle, and TV display size.

The Videos are temporally and spatially aligned and analog noise is normalized before starting the JND. Our JND implementation generates a Mean Opinion Score (MOS) on a scale from 0-100 where less than 5 is excellent video quality. For more information on JND, read Sarnoff Laboratories' White Paper.
