-metr blurring [over <color components>] -metr blurring_delta [over <color components>]

Algorithm description

This metric allows you to compare power of blurring of two images. If value of the metric for first picture is greater than for second, it means that second picture is more blurred, than first.

Main features: this metric is fast and doesn’t require source video.

This method estimates color variance in the neighborhood of a pixel and computes average variance. This metric has 2 variations:
