In order to image recognition using a register-type quantum computer consisting of electronic spins, this paper presents a unitary transformation for quantum state image representation of input image, and another unitary transformation for matching (or similarity computation) between input image and reference image data. Moreover, it shows some improved image recognition algorithms by quantum computer, based on Gram-Schmidt's orthogonalization.
