• Spatial localization: interpolating first- and second-order visual structure.

  سند علمی۲۰۰۹Journal of visionDavid R Badcock, Paul V McGraw, Russell Bridle, Jude Cullity

  Human observers are able to localize the relative position of objects defined by Gaussian variations in either luminance (1st order) or contrast (2nd order). However, positional sensitivity is significantly poorer for 2nd- than for 1st-order stimuli. These judgments require the v

• A new approach to spatial data interpolation using higher-order statistics

  سند علمی۲۰۱۴Shen Liu, Vo Anh, James McGree, Erhan Kozan

  Interpolation techniques for spatial data have been applied frequently in various fields of geosciences. Although most conventional interpolation methods assume that it is sufficient to use firstand second-order statistics to characterize random fields, researchers have now reali

• First-order and second-order visual processes in the perception of motion and tilt.

  سند علمی۱۹۹۱Vision researchG Mather

  It has been known for many years that the mammalian visual system contains neurones which respond selectively to the orientation of contours in the image, and to the direction of their movement. Numerous perceptual studies have also found evidence for the existence of orientation

• Interpolation-based second-order monotone finite volume schemes for anisotropic diffusion equations on general grids

  سند علمی۲۰۱۴J. Comput. PhysicsJiming Wu, Zhiming Gao

  We propose two interpolation-based monotone schemes for the anisotropic diffusion problems on unstructured polygonal meshes through the linearity-preserving approach. The new schemes are characterized by their nonlinear two-point flux approximation, which is different from the ex

• Spatial pooling in the second-order spatial structure of cortical complex cells

  سند علمی۲۰۰۰Vision ResearchKo Sakai, Shigeru Tanaka

  We investigate what computational mechanisms give rise to the nonlinearity of complex cell responses in the primary visual cortex. Complex cells are characterized by their nonlinear spatial properties such as spatial phase invariance and nonlinear spatial additivity. We carried o

• Features of the second-order visual filters sensitive to the spatial frequency modulations

  سند علمی۲۰۱۳M. B. Miftakhova, V. V Babenko

  We investigated selectivity of 2 nd order visual filters sensitive to the spatial frequency (SF) modulations to orientation and to SF of modulation. We carried out psychophysical experiment using masking paradigm. It was found that 2 nd order filters are selective to SF of modula
