Struct SsimMetric 

pub struct SsimMetric {
    pub window_size: u32,
    pub perfect_threshold: f32,
    pub accept_threshold: f32,
}

Structural Similarity Index Measure Range: -1 to 1 (1 = identical, 0 = no similarity)

Fields

window_size: u32

Window size for local comparison

perfect_threshold: f32

Threshold for “pixel perfect”

accept_threshold: f32

Threshold for “acceptable”
