ModelFest.df {MPDiR}

Contrast Sensitivity of the Observers from the ModelFest Consortium

Description

The data set contains the log contrast sensitivity measurments for the 43 stimuli used in the ModelFest consortium with 4 repeats for each of the 16 observers.

Usage

data(ModelFest.df)

Format

A data frame with 2752 observations on the following 3 variables.

LContSens

a numeric vector indicating the measured log contrast sensitivity, inverse of the log contrast threshold

Obs

a factor with 16 levels, indicating the initials of the observers

Stim

a factor with 43 levels coding each of the stimuli standardized for this study

Details

The ModelFest consortium was composed of a group of investigators from 10 laboratories who undertook to obtain measures of contrast sensitivity on a set of standardized achromatic stimuli, varying in spatial configuration, using a standardized set of procedures.
