Crate fast_ssim2

Structs§

Blur: Structure handling image blur with selectable implementation.
Frame: Represents a raw video frame
LinearRgb: Contains an RGB image in a linearized color space.
LinearRgbImage: Internal linear RGB image representation.
Plane: One data plane of a frame.
Rgb: Contains an RGB image.
Ssimulacra2Config: Configuration for SSIMULACRA2 computation.
Ssimulacra2Reference: Precomputed SSIMULACRA2 reference data for fast repeated comparisons.
Yuv: Contains a YCbCr image in a color space defined by YuvConfig.
YuvConfig: Contains the configuration data for a YCbCr image.

ColorPrimaries: Indicates the chromaticity coordinates of the source colour primaries as specified in Table 2 in terms of the CIE 1931 definition of x and y as specified by ISO 11664-1.
MatrixCoefficients: Describes the matrix coefficients used in deriving luma and chroma signals from the green, blue and red or X, Y and Z primaries.
SimdImpl: SIMD implementation backend for all operations (blur, XYB conversion, SSIM computation).
Ssimulacra2Error: Errors which can occur when attempting to calculate a SSIMULACRA2 score from two input images.
TransferCharacteristic: Either indicates the reference opto-electronic transfer characteristic function of the source picture as a function of a source input linear optical intensity input Lc with a nominal real-valued range of 0 to 1 or indicates the inverse of the reference electro-optical transfer characteristic function as a function of an output linear optical intensity Lo with a nominal real-valued range of 0 to 1.

compute_frame_ssimulacra2: Computes the SSIMULACRA2 score with default configuration (safe SIMD).
