Quantum multidimensional color images similarity comparison

Based on the representation of quantum multidimensional color image, a complete scheme of solving the similarity of two quantum multidimensional color images is studied in depth. The two cases, the color image with segmentation information and without segmentation information, are considered, respectively. First, two images are connected together to form a new “link-state” according to the specific generation circuit. Then, through the Hadamard transformation on the link-state and repeated observations, the similarity value of the two quantum multidimensional color images is obtained. The simulation experiments, especially the two satellite images with a short interval and the two 3/4-color-alike color images with corresponding segmentation information, also show a wonderful performance, which drives the explorations on the multiple quantum color images processing.
