ABSTRACT:
A device for discriminating an attribute of an image in a block area contained in a document image includes a device for performing a Fourier transformation based on image data in the block area and for determining a spatial frequency spectrum relating to the image in the block area; and a neural network for outputting a discrimination result as to whether or not the attribute of the image in the block area is a halftone dot image based on the spatial frequency spectrum output from the Fourier transform device.
