Joint entropy for space and spatial frequency domains estimated from psychometric functions of achromatic discrimination.

Joint entropy for space and spatial frequency domains estimated from psychometric functions of achromatic discrimination.

We used psychometric functions to estimate the joint entropy for space discrimination and spatial frequency discrimination. Space discrimination was taken as discrimination of spatial extent. Seven subjects were tested. Gábor functions comprising unidimensionalsinusoidal gratings (0.4, 2, and 10 cpd...
