Abstract
A method for monitoring a fluid release plume emitted by an industrial plant and/or an underground hydrocarbon fluid deposit into an adjacent space comprises:
- a) monitoring the space by means of a video camera during a selected period of time to generate an input video movie of the space;b) decomposing the generated input video movie into a series (s) of different spatial frequency bands;c) filtering the series (s) of spatial frequency bands by means of at least one temporal filter;d) amplifying the series (s) of filtered spatial frequency bands by a series of selected amplification factors (α1, α2, . . . −αs), wherein at least one amplification factor (α1) differs from the other amplification factors (α2, . . . −αs); ande) reconstructing an output video movie of the space in which the fluid release plume is enhanced by displaying a recomposition of the series of amplified filtered spatial frequency bands.
