This paper studies the relevance of the conformal camera to computational vision with a particular focus on stereopsis. First we review projective Fourier analysis of the conformal camera and point to its unique attributes for modeling physiological aspects of perception. Then we design the head–eye–visual cortex integrated system with each eye modeled by the conformal camera. It provides a bio...

A general asymptotic framework is developed for studying consistency properties of principal component analysis (PCA). Our framework includes several previously studied domains of asymptotics as special cases and allows one to investigate interesting connections and transitions among the various domains. More importantly, it enables us to investigate asymptotic scenarios that have not been cons...

This paper presents a face recognition based on the fusion of the intensity image and stereo depth map at the score level. The 3D surfaces are reconstructed from the stereo face images using stereo vision technique. The curvelet transform is a multiresolution method, which is used to extract features from depth and intensity images independently. Then, principal component analysis (PCA) is used...

in order to sustainable use of rangelands, it is necessary to recognize water, soil, and vegetation cover and analyze their relationships. physical and chemical properties of soil are effective in distribution of plant species in local area. to determine the effects of some soil properties on species distribution of eurotia ceratoides and stipa barbata in baghedar summer region of bafgh, three ...

This paper employs one-dimensional numerical ground response analysis models to investigate seismic response of shallow cohesive and non-cohesive soil deposits on vertical propagation of horizontal shear waves. Soil response is modelled by traditional equivalent-linear (EL) frequency-domain analysis using DEEPSOIL software and nonlinear (NL) time-domain analysis using OPENSEES software. The ana...

light is never being distributed homogeneously and it forms a gradient over biomass. the unidirectional nature of light gives rise to a vertical gradient of light intensity as a function of depth. the maximum depth of the light zone suitable for phytoplankton photosynthesis is designated as the euphotic depth. this study was designed to test the hypothesis of mixing depth of phytoplankton and i...
