Abstract
An image matching device includes: a mixed image generation portion generating a mixed image in an operation satisfying linearity, the mixed image being obtained by multiplying each of two or more recorded images and each of phase components of a complex plane different from each other and adding multiplied recorded images; a complex similarity image generation portion generating a complex similarity image through a similarity operation between one or more input image and the mixed image; and a similarity obtain portion obtaining similarity from a projected component of the complex similarity image toward a vector of the phase component.
Claims20
An image matching device comprising:
- a mixed image generation unit that generates a mixed image in an operation satisfying linearity, the mixed image being obtained by multiplying each of two or more recorded images by each of phase components of a complex plane different from each other and adding multiplied recorded images;
- a complex similarity image generation unit that generates a complex similarity image through multiplying one or more input image by the mixed image;
- and
- a similarity obtain unit that obtains similarity from a projected component of the complex similarity image toward a vector of the phase component.
An image matching method comprising:
- generating a mixed image in an operation satisfying linearity, the mixed image being obtained by multiplying each of two or more recorded images by each of phase components of a complex plane different from each other and adding multiplied recorded images;
- generating a complex similarity image through multiplying one or more input image by the mixed image;
- and
- obtaining similarity from a projected component of the complex similarity image toward a vector of the phase component.
