Abstract:
1. An image processing apparatus for performing image similarity comparison processing, comprising: a storing means for storing an original image as a comparison target image; an input means for inputting a comparison source image; an acquiring means for acquiring respective paper sizes from the comparison target image and comparison source image; an extracting means for extracting positional information and a size of a block having an attribute as block information from each of the comparison target image and the comparison source image; a normalizing means for normalizing the block information by using the respective paper size; a first comparison means for comparing a layout of the comparison target image and a layout of the comparison source image using the respective normalized block information a determination means for determining whether the size of the original image is a predetermined size; and a second comparison means for comparing, when it has been determined by the determination means that the size of the original image is not the predetermined size and when the layout of the comparison target image does not correspond to the layout of the comparison source image as a result of comparison by the first comparison means, the layout of the comparison target image and the layout of the comparison source image using the respective unnormalized block information.
