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 ) . CCri,rj denotes a point or a matrix element of a cross correlation matrix or of a “correlogram” CC, Imgi,j denotes a pixel (i, j) of a recorded matrix-shaped image Img and Tk,l denotes a pixel (k,l) of a matrix-shaped reference image or reference template T with (NTx·NTY) pixels, which contains a reference object.

Abstract: The presence of a stationary object is to be reliably recognized. Thereto, a presence detection device for detecting a presence of an object in its environment is provided, which comprises a movement detection unit for detecting an initial movement of the object in the environment of the presence detection device and for outputting a movement signal depending on the detection as well as a control unit for generating an activation signal depending on the movement signal. Moreover, the presence detection device comprises a camera, which can be activated by the activation signal, for obtaining a video signal of the environment of the presence detection device and an evaluation unit for generating a presence signal relating to the presence of the object by evaluating the video signal.
