Algorithms employed to identify and quantify images on digitised images
mostly employ contiguous-pixel (e.g. PISA [based on APM software by Irwin {1985}])
or median-filtering techniques and thus miss extended low surface-brightness
features. Searches for low surface brightness galaxies (LSBGs) have therefore so
far concentrated on eye-ball searches of Schmidt survey plates. To overcome the
subjectiveness of eyeball searches and eliminate the inherent problems in current
object-detection algorithms we have investigated other techniques.
