Human perception of colour closely resembles the which clour model
Answers
There are many theories that have studied and postulated about the human perception of color vision. One of the most important theories could be the - The Hue Saturation Intensity (HSI) color model.
This Hue Saturation Intensity (HSI) color model is known to resemble the properties related to color sensing of human vision on a very close note. In this color model, the colors are specified using terms - hue, saturation, and intensity. These terms resemble very closely resemble the visionary perceptions and description of color by humans.
The HSI color space is very important and attractive color model for image processing applications because it represents color s similarly how the human eye senses colors.
The HSI color model represents every color with three components: hue ( H ), saturation ( S ), intensity ( I ). The below figure illustrates how the HIS color space represents colors.
The Hue component describes the color itself in the form of an angle between [0,360] degrees. 0 degree mean red, 120 means green 240 means blue. 60 degrees is yellow, 300 degrees is magenta.
The Saturation component signals how much the color is polluted with white color. The range of the S component is [0,1].
The Intensity range is between [0,1] and 0 means black, 1 means white.
As the above figure shows, hue is more meaningful when saturation approaches 1 and less meaningful when saturation approaches 0 or when intensity approaches 0 or 1. Intensity also limits the saturation values.
To formula that converts from RGB to HSI or back is more complicated than with other color models, therefore we will not elaborate on the detailed specifics involved in this process.
