SUMMARY Patent of Invention: "SYSTEMS AND METHODS FOR TIME-SPACE DOMAIN FILTERING AND TIME-SPACE DOMAIN DISCRIMINATION". The present invention relates to computer systems and methods that combine global wavelength domain ("fk domain") domain filters with localized self-image based event selection to generate a resulting wave field with reduced filter impressions. at the grouped edges, noise reduction and proper power smoothing treatment are disclosed. The methods are performed by applying filters to the complete set of seismic data grouped in the f-k domain in order to obtain a resulting wave field from recorded particle velocity and / or pressure data. The filter output is iteratively decomposed according to local dive values, using single value decomposition ("SVD") self-image processing. The same sample locations are extracted using an SVD from the input, in addition to generating the input for subsequent iteration with removed data already processed. Self-image processing methods allow for the correct treatment of spatially smoothed energy in f-k domain filtering.
