Ancillary Objects
colour.contrast
optical_MTF_Barten1999 (u[, sigma]) |
Returns the optical modulation transfer function (MTF) \(M_{opt}\) of the eye using Barten (1999) method. |
pupil_diameter_Barten1999 (L[, X_0, Y_0]) |
Returns the pupil diameter for given luminance and object or stimulus angular size using Barten (1999) method. |
sigma_Barten1999 ([sigma_0, C_ab, d]) |
Returns the standard deviation \(\sigma\) of the line-spread function resulting from the convolution of the different elements of the convolution process using Barten (1999) method. |
retinal_illuminance_Barten1999 (L[, d, …]) |
Returns the retinal illuminance \(E\) in Trolands for given average luminance \(L\) and pupil diameter \(d\) using Barten (1999) method. |
