Abstract

See full text

The invention relates to a method for automatically detecting a pre-defined image pattern in an original picture, wherein pixel data from said original picture are looked through by means of a processing step, including at least one transform, to find said pre-defined image pattern, wherein according to the invention said processing is split up into at least two stages, wherein a first stage with a coarse processing is to detect locations in the original picture imposing an increased likelihood that the pre-defined image pattern, can be found there, and wherein a second stage with a refined processing is applied to the locations to identify the pre-defined image pattern.
