Hyperspectral Intensity Color Space

The HSI color space is a color model used in remote sensing and computer graphics.

This color space is used for 3D modeling, computer vision, and other applications where color accuracy is crucial.

HSI is based on the concept of 3D vector space, which is more intuitive and easier to understand than other color models.

Hue (θ)

Intensity (ρ)

Saturation (σ)

            θ ∈ [0°, 360°]
            ρ ∈ [0, 1]
            σ ∈ [0, 1]

HSI to RGB Conversion

Convert HSI color space to RGB color space using the following formula:

θ = (H + 90°) % 360° ρ = (I + 128) % 256 σ = S 
            R = ρ * cos(θ)
            G = ρ * cos(σ)
            B = ρ * cos(θ + 120°)
