Enum image_compare::Algorithm

source · [−]

pub enum Algorithm {
    RootMeanSquared,
    MSSIMSimple,
}

Expand description

The enum for selecting a grayscale comparison implementation

Variants

`RootMeanSquared`

A simple RMSE implementation - will return: $1-\sqrt{\frac{(\sum_{x,y=0}^{x,y=w,h}\left(f(x,y)-g(x,y)\right)^2)}{w*h}}$

`MSSIMSimple`

a simple MSSIM implementation - will run SSIM (implemented as on wikipedia: $\mathrm{SSIM}(x,y)={\frac {(2\mu _{x}\mu _{y} c_{1})(2\sigma _{xy} c_{2})}{(\mu _{x}^{2} \mu _{y}^{2} c_{1})(\sigma _{x}^{2} \sigma _{y}^{2} c_{2})}}$ ) over 8x8 px windows and average the results
