Abstract:
    We have developed an automatic technique to search for
    low-surface-brightness (LSB) galaxies in the local Universe
    (v<=5000km/s) using the automated plate measuring (APM) scan data
    of UK Schmidt photographic plates. We optimized our technique and
    selection criteria by surveying the known LSB galaxies in the Fornax
    cluster. Plate-to-plate magnitude calibrations were carried out using
    independent CCD sequences. The galaxies we detected are brighter
    than 20Bmag, have scalesizes greater than 3arcsec and a central
    surface brightness fainter than 22.5mag/arcsec^2^. In total 2435 LSB
    galaxies were detected over a total area of 2187deg^2^. The survey
    covers the Fornax cluster, NGC 1400, Sculptor and Dorado groups
    and the field between. We detect on average 32 LSB galaxies per
    5.8{deg}x5.8{deg} field. We have estimated the background (v>5000km/s)
    contamination in three ways: by numerical modelling, using a limited
    redshift sample and comparing our Fornax data with those of
    Ferguson. The results indicate a contamination of about 19 galaxies
    per field.
