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 CCdenotes a point or a matrix element of a cross correlation matrix or of a 'correlogram' CC, Imgdenotes a pixel (i, j) of a recorded matrix-shaped image Img and Tdenotes a pixel (k,l) of a matrix-shaped reference image or reference template T with (NTx·NTY) pixels, which contains a reference object.
