Crate dssim_core

The library interface is awfully abstract, because it strives to efficiently, and very accurately, support several pixel types. It also allows replacing some parts of the algorithm with different implementations (if you need higher accuracy or higher speed).

Structs

• Dssim
  Configuration for the comparison
• DssimImage
  Abstract wrapper for images. See Dssim::create_image()
• LAB
  L*a*b*b, but using float units (values are 100× smaller than in usual integer representation)
• SsimMap
  Detailed comparison result
• Val
  Result of comparison as f64

Traits

• ToLABBitmap
  Convert image to L*a*b* planar
• ToRGBAPLU
  RGBA Premultiplied Linear-light Unit scale

Functions

• new
  Create new context for a comparison

Type Aliases

• RGBAPLU
  RGBA, but: premultiplied alpha, linear (using sRGB primaries, but not its gamma curve), f32 unit scale 0..1
• RGBLU
  RGB, but: linear (using sRGB primaries, but not its gamma curve), f32 unit scale 0..1
