Computational framework of the visual sensory system based on neuroscientific evidence of the ventral pathway
2023, Cognitive Systems ResearchCitation Excerpt :Another function attributed to the primary visual cortex (V1) is the enhancement of the spatial invariance of the edges detected by the simple cells; biologically this process is performed by the complex cells. The mathematical model used to mimic the behavior of complex cells is called the Gabor energy model, used and accepted in various works to represent the receptive field of complex cells (Adelson & Bergen, 1985; Field, 1987; Mallot, 2013; Pollen et al., 1988; Shams & von der Malsburg, 2002; Spitzer & Hochstein, 1988). The advantage of using complex cells in this model is the reduction of edge information with specific orientations, especially if the image generates a great deal of edge information in the simple V1 cells.
Representation of higher-order statistical structures in natural scenes via spatial phase distributions
2016, Vision ResearchCitation Excerpt :While a predominant view on the complex cells and cells in the higher visual area is that they are phase invariant (Albrecht et al., 1980;Movshon et al., 1978; Skottun et al., 1991), recent studies report evidence of phase sensitive cells (Crowder et al., 2007; Felsen et al., 2005; Hietanen et al., 2013; Mechler & Ringach, 2002; Mechler et al., 2002). Responses of phase invariant complex cells are described by an energy model (Eq. (3)) (Adelson et al., 1983; Hyvärinen & Hoyer, 2000; Hyvärinen & Köster, 2006; Pollen, Gaska, & Jacobson, 1988). Indeed, the two thirds of the complex RFs examined in this study exhibited uniform phase distributions (see Figs. 4 and A6).
