72 p, 938.8 KB Using digital photography to study animal coloration / Stevens, Martin (University of Bristol) ; Parraga, Carlos Alejandro (University of Bristol. Department of Experimental Psychology) ; Cuthill, Innes C. (University of Bristol) ; Partridge, Julian C. (University of Bristol) ; Troscianko, Tom S. (University of Bristol. Department of Experimental Psychology)
In understanding how visual signals function, quantifying the components of those patterns is vital. With the ever-increasing power and availability of digital photography, many studies are utilizing this technique to study the content of animal colour signals. [...]

20 p, 233.6 KB Color and luminance information in natural scenes / Parraga, Carlos Alejandro (University of Bristol. Department of Psychology) ; Brelstaff, G. (University of Bristol. Department of Psychology) ; Troscianko, Tom (University of Bristol. Department of Psychology) ; Moorhead, I. R. (Defence Evaluation and Research Agency (Regne Unit))
The spatial filtering applied by the human visual system appears to be low pass for chromatic stimuli and band pass for luminance stimuli. Here we explore whether this observed difference in contrast sensitivity reflects a real difference in the components of chrominance and luminance in natural scenes. [...]

14 p, 397.6 KB Spatiochromatic properties of natural images and human vision / Parraga, Carlos Alejandro (University of Bristol. Department of Experimental Psychology) ; Troscianko, Tom (University of Sussex) ; Tolhurst, D.J. (University of Cambridge. Department of Physiology)
The human visual system shows a relatively greater response to low spatial frequencies of chromatic spatial modulation than to luminance spatial modulation [1]. However, previous work [2, 3] has shown that this differential sensitivity to low spatial frequencies is not reflected in any differential luminance and chromatic content of general natural scenes. [...]

It has been suggested (Tadmor and Tolhurst, 1994 Vision Research34 541-554) that the psychophysical task of discriminating changes in the slope of the amplitude spectrum of a complex image may be similar to detecting differences in the degree of blur. [...]

Department of Experimental Psychology) ; Troscianko, Tom (University of Bristol. Department of Experimental Psychology) ; Tolhurst, D. J. (University of Cambridge. Department of Physiology)
A fundamental tenet of visual science is that the detailed properties of visual systems are not capricious accidents, but are closely matched by evolution and neonatal experience to the environments and lifestyles in which those visual systems must work [1, 2, 3, 4, 5]. [...]

52 p, 1.0 MB The effects of amplitude-spectrum statistics on foveal and peripheral discrimination of changes in natural images, and a multi-resolution model / Parraga, Carlos Alejandro (University of Bristol. Department of Experimental Psychology) ; Troscianko, Tom (University of Bristol. Department of Experimental Psychology) ; Tolhurst, D.J. (University of Cambridge. Department of Physiology)
Psychophysical thresholds were measured for discriminating small changes in spatial features of naturalistic scenes (morph sequences), for foveal and peripheral vision, and under M-scaling. Sensitivity was greatest for scenes with near natural Fourier amplitude slope, perhaps implying that human vision is optimised for natural scene statistics. [...]
