Detailed Description

A temporal flicker channel.

This channel just keeps a memory trace of the previous frame and then does a basic center-surround processing on the difference between current and memorized input. The time constant determines how the memorized input should be updated when a new input arrives.

Member Data Documentation

Time constant of the channel, in seconds. This is used to determine how to update our memory of the previous frame as a new frame arrives. If the previous frame is more than a time constant older than the new one, it will be replaced by the new one for the next step of processing; otherwise a mix between both will be used, depending on the difference between old and new times.
