Linear

class randd.model.Linear(r, d, d_measure='psnr', ndim=1)

1D Linear rate-distortion function interpolator.

Extrapolation is enabled, but not always reliable.

Parameters

• r (NDArray) – Encoding representations.

• d (NDArray) – Corresponding distortions.

• d_measure (str) – Name of the distortion measure.

• ndim (int) – Number of dimensions of the RD function domain.

__call__(r)

Predict the distortion at the given representation.

Parameters

r (NDArray) – Input encoding representation.

Returns

Predicted distortion.

Return type

NDArray
