Feature request:
-- Decay filter, makes short flashes of light appear longer, with an
exponential decay curve. Like on an analog oscilloscope screen with long
persistence time. Could be used for videos of the night sky to make fast
meteors appear longer. Should work as follows:
For each pixel do: Multiply the RGB values from the previous output
frame with a decay constant in the range [0..1], for example 0.95. Use
these RGB values for the next output frame. But if the RGB value from
the next input frame is brigher than this, then use the brighter value.
I'm not sure about "decay" name for filter.
Decay is usually something else.
Please feel free to use a better name. I don't care about the name. You
understood how it should work?
