Feature matching
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.
RELATED TERMS--------------------------------------
Binocular
Using both eyes at the same time. Binocular vision is the most important element of depth perception.
Vision
The sense of sight.
Stereopsis
Also known as depth perception. The separation between the eyes provides for slightly different views of an object by each eye. The brain for the purpose of telling the location of an object in 3D space uses this difference in views between the eyes or disparity.
SIMILAR TERMS--------------------------------------
Feather River Hospital
The Feather River Hospital is a hospital in Butte, California, United States.
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.
PREVIOUS AND NEXT TERMS--------------------------------------
Formula
An alternative to breast milk, baby formula is usually milk-based but is also made from soy products.
Fraternal twins
Born at the same time but resulting from the fertilization of two different eggs, fraternal twins are no more genetically similar than siblings; identical twins result from the division of one fertilized egg and are genetically identical.
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.

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
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.
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.
