Opponent-process theory is a psychological and neurological model that accounts for a wide range of behaviors, including color vision. This model was first proposed in 1878 by Ewald Hering , a German physiologist, and later expanded by Richard Solomon , a 20th-century psychologist.
The image modification process is sometimes called color transfer or, when grayscale images are involved, brightness transfer function (BTF); it may also be called photometric camera calibration or radiometric camera calibration. The term image color transfer is a bit of a misnomer since most common algorithms transfer both color and shading ...
The opponent process is a color theory that states that the human visual system interprets information about color by processing signals from photoreceptor cells in an antagonistic manner. The opponent-process theory suggests that there are three opponent channels , each comprising an opposing color pair: red versus green , blue versus yellow ...
The visual system is organized hierarchically, with anatomical areas that have specialized functions in visual processing. Low-level visual processing is concerned with determining different types of contrast among images projected onto the retina whereas high-level visual processing refers to the cognitive processes that integrate information from a variety of sources into the visual ...
In psychology, parallel processing is the ability of the brain to simultaneously process incoming stimuli of differing quality. [1] Parallel processing is associated with the visual system in that the brain divides what it sees into four components: color, motion, shape, and depth.
Specificity of processing describes the increased recall value of a stimulus when presented in the method with which it was inputted. For example, auditory stimuli (spoken words and sounds) have the highest recall value when spoken, and visual stimuli have the highest recall value when a subject is presented with images. [6]
Color vision is categorized foremost according to the dimensionality of the color gamut, which is defined by the number of primaries required to represent the color vision. This is generally equal to the number of photopsins expressed: a correlation that holds for vertebrates but not invertebrates .
The general model of color psychology relies on six basic principles: Color may carry a specific meaning. Color meaning is either based in learned meaning or biologically innate meaning. The perception of a color causes evaluation automatically by the person perceiving. The evaluation process forces color-motivated behavior.
