Filling-In theory
|
|
Filling-In theory Idea that the brightness and color of interiors of homogeneous regions are determined by a process of lateral spread of neural activation that is initiated by units responding to abrupt changes in luminance and wavelength.
RELATED TERMS--------------------------------------
Homogeneous
Of the same type, or having the same characteristics.
Lateral
Toward the side, sideways.
SIMILAR TERMS--------------------------------------
Filler
An inactive substance used to make a product bigger or easier to handle. For example, fillers are often used to make pills or capsules because the amount of active drug is too small to be handled conveniently.
Filling
Restoration of lost tooth structure with metal, porcelain or resin materials.
PREVIOUS AND NEXT TERMS--------------------------------------
Full-term
A baby born between 38 and 42 weeks' gestation.
Fundal height
The distance between the top of a pregnant woman's uterus (called thefundus) to her pubic bone. Measured to determine fetal age.
Feature binding
The binding of features processed by different systems (audio, visual) or of different subsystems (motion, depth, color) to create a unified conscious percept.
Feature matching
In Binocular Vision and Stereopsis, disparity can be extracted from an image if features in the two corresponding binocular images are matchable e.g. lines to lines, dots to dots.
Fechner's Paradox
The fact that a monocular view may look brighter than a binocular view. Suppose that a scene is viewed through both eyes but that one eye sees it through a neutral filter that attenuates all wavelengths by a constant ratio. The filter does not distort the reflectances or ratios of light reaching the eye, but only its absolute intensity. If the filtered eye is entirely occluded the scene looks brighter and more vivid than with the filter despite the fact that less total light is reaching the two eyes and the reflectances are still the same.
Filling-In theory
First-Order statistics
Captures differences in overall brightness.
First-Order motion mechanisms
Captures motion information from moving objects or features that differ from the background in luminance.
Fixation
Alignment of the eyes so that the image of the fixated target falls on the area centralis. For animals with immobile eyes the alignment of the head towards the fixated target.
Flicker
Alternating levels of brightness.
Flicker photometry experiment
Stimuli consisting of a pair of different color test lights alternate. When the lights alternate slowly the pattern appears to change between the colors of the two lights. When the lights alternate rapidly observers fail to see the color modulation and instead perceive a dark-light modulation. Demonstrates that the temporal resolution for distinguishing blue-yellow is less than red-green which in turn is less than light-dark.
