<P>PROBLEM TO BE SOLVED: To provide an image pattern identification apparatus being applicable only to similar classes having a possibility of causing erroneous identification in a pinpoint manner. <P>SOLUTION: An image pattern identification apparatus includes an input subspace generation section 10, a dictionary subspace generation section 20, a similar class selection section 30, an input difference subspace generation section 40, a feature amount generation section 50, a dictionary difference subspace generation section 60, a similarity operation part 70, and an output section 80. The input difference subspace generation section 40 generates input difference subspaces Y<SB POS="POST">i</SB>and Y<SB POS="POST">j</SB>respectively. The feature amount generation section 50 generates feature amounts Y<SB POS="POST">ci</SB>and Y<SB POS="POST">cj</SB>respectively. The dictionary difference subspace generation section 60 generates a dictionary difference subspace D<SP POS="POST">PiPj</SP>. The similarity operation section 70 calculates dissimilarity G<SP POS="POST">PiPj</SP><SB POS="POST">Pi</SB>(X) and G<SP POS="POST">PiPj</SP><SB POS="POST">Pj</SB>(X) of the feature amounts Y<SB POS="POST">ci</SB>and Y<SB POS="POST">cj</SB>of the respective difference subspaces from the dictionary difference subspace D<SP POS="POST">PiPj</SP>. <P>COPYRIGHT: (C)2012,JPO&INPIT |
