colour.contrast.optical_MTF_Barten1999#
- colour.contrast.optical_MTF_Barten1999(u: ArrayLike, sigma: ArrayLike = 0.01) NDArrayFloat [source]#
Return the optical modulation transfer function (MTF) \(M_{opt}\) of the eye using Barten (1999) method.
- Parameters:
u (ArrayLike) – Spatial frequency \(u\), the cycles per degree.
sigma (ArrayLike) – Standard deviation \(\sigma\) of the line-spread function resulting from the convolution of the different elements of the convolution process.
- Returns:
Optical modulation transfer function (MTF) \(M_{opt}\) of the eye.
- Return type:
