Struct SsimOptions 

pub struct SsimOptions {
    pub window_size: usize,
    pub k1: f64,
    pub k2: f64,
    pub bit_depth: u32,
}

Knobs shared by every SSIM variant.

Fields

window_size: usize

Side of the local window. Default 11, as in every reference.

k1: f64

Luminance stability constant: c1 = (k1·L)². Default 0.01.

k2: f64

Contrast stability constant: c2 = (k2·L)². Default 0.03.

bit_depth: u32

Sample bit depth, which sets the dynamic range L = 2^bit_depth - 1. Default 8.

Implementations

impl SsimOptions

pub fn dynamic_range(&self) -> f64
