Abstract
Image analysis for comparison utilizes a combined image distance determined between the one or more captured images and the one or more reference images from a dual path analysis. The dual path analysis can comprise a first image analysis based on histograms of image colors and a second image analysis based a one-dimensional power spectral density of a black and white instance of the one or more captured images and the one or more reference images. In one case, the one-dimensional power spectral density derived by integrating a Discrete Fourier Transform of a two-dimensional image over annular rings of substantially equal area starting from the center of the two-dimensional image.
