Perception 34:1003-8. 2005....
Color constancyDavid H Foster

Vision Res 51:674-700. 2011....- Color constancy in natural scenes explained by global image statisticsDavid H Foster
Sensing, Imaging, and Signal Processing Group, School of Electrical and Electronic Engineering, University of Manchester, Manchester, United Kingdom
Vis Neurosci 23:341-9. 2006..By contrast, a spatial-frequency analysis of the images showed that the gradient of the luminance amplitude spectrum accounted for only 5% of the variance... 
Confusing the moon's whiteness with its brightnessDavid H Foster
Faculty of Life Sciences, The University of Manchester, Manchester, UK
Clin Experiment Ophthalmol 33:574-5. 2005- Color constancy in natural scenes with and without an explicit illuminant cueKinjiro Amano
Sensing, Imaging, and Signal Processing Group, School of Electrical and Electronic Engineering, University of Manchester, Manchester, United Kingdom
Vis Neurosci 23:351-6. 2006..Even when the sky was eliminated from view, color constancy did not worsen. Judging surface color in natural scenes seems to be independent of an explicit illuminant cue... - Visual search in natural scenes explained by local color propertiesKinjiro Amano
School of Electrical and Electronic Engineering, University of Manchester, Manchester M13 9PL, UK
J Opt Soc Am A Opt Image Sci Vis 29:A194-9. 2012..A similar level of variance was accounted for by observers' fixations. These results suggest that local color can be as influential as gaze position in determining observers' search performance in natural scenes... - Information limits on neural identification of colored surfaces in natural scenesDavid H Foster
Visual and Computational Neuroscience Group, University of Manchester Institute of Science and Technology, Manchester, UK
Vis Neurosci 21:331-6. 2004..The standard deviation over the 25 scenes was, on average, approximately 1 bit, suggesting that the neural coding of surface color can be optimized independent of location for any particular range of illuminants... - Minimalist surface-colour matchingKinjiro Amano
Computational Neuroscience Group, Faculty of Life Sciences, University of Manchester, Manchester M60 1QD, UK
Perception 34:1009-13. 2005..The patterns had either 49 surfaces or a minimal 2 surfaces. No significant effect of number was found, suggesting that illuminant estimates are unnecessary for surface-colour matching... - Perceptual limits on low-dimensional models of Munsell reflectance spectraEmma K Oxtoby
Computational Neuroscience Group, Faculty of Life Sciences, Moffat Building, University of Manchester, Manchester M60 1QD, UK
Perception 34:961-6. 2005..In all experimental conditions, observers required, on average, at least 5 basis functions for discrimination performance to be at chance, thus placing a lower limit on the dimensionality of models of Munsell reflectance spectra... - Protanopic observers show nearly normal color constancy with natural reflectance spectraRigmor C Baraas
Visual and Computational Neuroscience Group, University of Manchester Institute of Science and Technology, Manchester, UK
Vis Neurosci 21:347-51. 2004.... - A simple nonparametric method for classifying eye fixationsMatthew S Mould
School of Electrical and Electronic Engineering, University of Manchester, Manchester, UK
Vision Res 57:18-25. 2012..The method was applied to the recorded data to illustrate the variation of mean fixation duration and saccade amplitude across observers and scenes... - Uniformity and asymmetry of rapid curved-line detection explained by parallel categorical coding of contour curvatureDavid H Foster
Visual and Computational Neuroscience Group, Department of Optometry and Neuroscience, University of Manchester Institute of Science and Technology, M60 1QD, Manchester, UK
Vision Res 42:2163-175. 2002.... - Model-free estimation of the psychometric functionKamila Zychaluk
University of Manchester, Manchester, England
Atten Percept Psychophys 71:1414-25. 2009..The local linear method frequently performed better and never worse than the parametric ones. Supplemental materials for this article can be downloaded from app.psychonomic-journals.org/content/supplemental... - Statistics of spatial cone-excitation ratios in natural scenesSérgio M C Nascimento
Department of Physics, University of Minho, Braga, Portugal
J Opt Soc Am A Opt Image Sci Vis 19:1484-90. 2002..Almost-invariant ratios were common, suggesting that they represent a reliable property of the natural visual environment and a suitable foundation for visual color constancy... - Anomalous trichromats' judgments of surface color in natural scenes under different daylightsRigmor C Baraas
Department of Optometry and Visual Science, Buskerud University College, Norway
Vis Neurosci 23:629-35. 2006..The results are considered in relation to the spectral coverage of cones, rod intrusion, and the characterization of anomalous trichromacy by the Rayleigh match... - Color constancy: phenomenal or projective?Adam J Reeves
Department of Psychology, Northeastern University, Boston, Massachusetts 02115, USA

Department of Physics, Minho University, Campus de Gualtar, Braga, Portugal
Vis Neurosci 23:555-9. 2006..2. Although a large variation of performance across the nine images tested was found when errors were expressed in CIELAB units, little variation was obtained when they were expressed in S-CIELAB units... - Recognizing novel three-dimensional objects by summing signals from parts and viewsDavid H Foster
Visual and Computational Neuroscience Group, Department of Optometry and Neuroscience, University of Manchester Institute of Science and Technology, Manchester M60 1QD, UK
