Visualization

Metric’s visualization difference of Y-planes between two consecutive frames + 128. So, grey color (128, 128, 128) means that brigtness of a pixel is the same as at the previous frame.

Visualization example

Plots

Metric’s plot is making after all measurements. “Zero” value means that current frame exist, “one” - that it is dropped. The resulting metric’s value is number of drop-frames.

Plot's example

Algorithm

For each frame difference with the previous one is calculating. Metric’s value is 1 if frames are identical, 0 otherwise.
