An apparatus, method and computer program for recognizing one or more images within digitized image data that might include a target image desired to be located. The system generates a set of domain blocks from the image data where each domain block represents a discrete portion the image data and a set of range blocks from one or more target images. Either the domain blocks, the range blocks, or both, are transformed by one or more substantially affine transformations with predetermined coefficients to create possible variants of the images. A comparison between the blocks is made to determine similarity, and includes at least a measurement of whether better matching is achieved when a range block is chosen from image data representing the image which is the source of the domain block or when chosen from other image data.
