RGB to HSV
RGB (Red Green Blue) and HSV (Hue Saturation Value) are two different color models used to describe colors in digital images. RGB is an additive color model that describes colors in terms of the amounts of red, green, and blue light that are combined to create a specific color. On the other hand, HSV is a perceptual color model that describes colors in terms of their hue, saturation, and value.
Hue refers to the color's position on the color spectrum, and it is typically described as a number between 0 and 360 degrees. Saturation refers to the intensity of the color, or how much it differs from a neutral gray of the same brightness. It is typically described as a percentage between 0% and 100%. Value, also known as brightness or lightness, refers to the amount of light reflected by the color. It is typically described as a percentage between 0% (black) and 100% (white).
The conversion from RGB to HSV involves a series of mathematical calculations that map the red, green, and blue values of a color to its corresponding hue, saturation, and value. This conversion can be useful for image processing tasks such as color correction, color filtering, and color segmentation.
