Plateau

The Plateau metafeature detects when a continuous signal is not changing, give or take noise. The output from Plateau is a list of tuples consisting of three parameters:

• midTime: This is as for Increasing.
• average: This is as for Increasing.
• duration: This is as for Increasing.

It operates on a single channel. It accepts the following settings:

• channel: This is as for Increasing.
• exceptions: This is as for Increasing. However, because it can be trickier to detect plateaus the default is higher. Default value is 2.
• useRelativeTime: This is as for Increasing.

• useRelativeHeight: This is as for Increasing.

• minDurn: This is as for Increasing; however, because it is difficult to detect if the signal is ``flat'', a longer interval is required. Default value is 4 frames.
