  • Patent number: 10268922
    Abstract: A method for image processing is disclosed. A non-normalized cross correlation is used to produce a cross correlation matrix between a recorded image, which contains at least one captured object, and a reference image, which contains a reference object. A comparison between a plurality of regions of the correlation matrix is carried out for a respectively captured object. A decision as to whether the respectively captured object and the reference object correspond is made on the basis of a result of the comparison. The non-normalized cross correlation is carried out by means of the equation CC ri , rj = ? x = 0 NTx ? ? ? y = 0 NTy ? ? T x , y · Img ( x - ri ) , ( y - rj ) .
