Crate dssim [−] [src]
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

Configuration for the comparison |
| DssimImage |
Abstract wrapper for images. See |
| LAB |
L*a*b*b, but using float units (values are 100× smaller than in usual integer representation) |
