Discriminability of suprathreshold compound spatial frequency gratings.
We have investigated the detectability of small contrast changes in compound suprathreshold gratings, containing two sinusoidal components. We examined the relationship between the detectability of changes in each of the components alone and the detectability of changes in the two components together. It was found that for the pairs of spatial frequencies 1 and 9 c/deg there is a square law sum...
متن کاملOrientation and spatial-frequency discrimination for luminance and chromatic gratings.
We have examined the accuracy of orientation and spatial-frequency discrimination for sine-wave gratings that vary in either luminance or color. The equiluminant chromatic gratings were modulated along either a tritanopic confusion axis (so that they were detectable on the basis of activity in only the short-wavelength-sensitive cones) or an axis of constant short-wavelength-sensitive cone exci...
متن کاملDiscovering Spatial Interaction Patterns
Advances in sensing and satellite technologies and the growth of Internet have resulted in a vast amount of uncertain spatial data. Extracting interaction patterns from these uncertain data is a challenging task. In this paper, we propose to model the spatial features in a continuous space through the use of influence functions. For each feature type, we build an influence map that captures the...
متن کاملDiscrimination of compound gratings: Spatial-frequency channels or local features?
Models based on spatial-frequency channels and local features provide alternative explanations for suprathreshold pattern discrimination. We compared psychophysical discrimination data with the predictions of the Wilson and Gelb channel model and three local-feature models. The features were peak-valley local contrast, peak-peak local contrast, and luminance gradients. We measured visual sensit...
