Abstract

System og fremgangsmåte for billed- vurdering ifølge differansebildet som er innhentet fra et digitalisert videosig- nal i et overvåkningskamera, hvor bil- ledpunkter som forandrer seg blir mar- kert ved hjelp av en objektsekstraktor hvor sammenhengende billedpunkter (ob- jekter) undersøkes. De ekstraherte ob- jektene blir tilordnet lagrede objekter til et foregående bilde. Ved vurdering av bestemte relevansekriterier, som er avhengig av forandringene til objekts- posisjonene med hensyn til forskjellig melderelevans for forhåndsbestemte bil- ledsoner A, B, C, følger en soneavhengig meldingsavgivelse.
