noise_e: Receptor noise

In colourvision: Colour Vision Models

Description

Receptor noise either provided by the user or based on noise-to-signal ratio of a single photoreceptor and the relative abundance of photoreceptor types in the retina. This function is used internally in Receptor Noise Limited models.

Usage

noise_e(noise, e, v, n)

Arguments

noise	Logical. Whether receptor noise is provided (noise = TRUE) or calculated from photoreceptor relative abundances (noise = FALSE)
e	Receptor noise of each photoreceptor type. It is used when noise = TRUE
v	Noise-to-signal ratio of a single photoreceptor.
n	Relative abundance of the photoreceptor in the retina.
