Abstract
Assessment of de-interlaced video quality is determined automatically by de-interlacing interlaced video content using a reference de-interlacer and a test de-interlacer. The reference de-interlacer produces a result of known quality and the test de-interlacer is one which is being assessed. The result from each de-interlacer is compared to reference video content to derive a signal-to-noise ratio for each relative to the reference video content. The difference in the signal-to-noise ratios is compared against a predefined threshold. If the difference is within the range defined by the threshold, the test de-interlacer is determined to produce an acceptable product.
