In this paper, the property of spatial shift operation on image reconstruction from amplitude and phase information in two-dimensional Fractional Fourier Transform (2D-FRFT) is studied through mathematical analysis and computer simulations. From the analysis presented in this paper, the phase information is spatial shift-invariant for image reconstruction in the 2D-FRFT domain while the amplitude...
In this paper, it presents a novel approach for selecting discriminative features in multimodal information fusion based discriminative multiple canonical correlation analysis (DMCCA), which is the generalized form of canonical correlation analysis (CCA), multiple canonical correlation analysis (MCCA) and discriminative canonical correlation analysis (DCCA). The proposed approach identifies the discriminative...
Computer recognition of human emotional states is an important component for efficient human-computer interaction. In this paper we explore an approach for recognition of human emotion from the visual information. We perform feature selection by using the two dimensions fractional Fourier transform. As a generalization of Fourier transform, the two dimensions fractional Fourier transform (2D-FrFT)...
