objectNormalize: Object Intensity Normalization

Description

Normalizes a matrix to [0,1].

Usage

objectNormalize(
  mat,
  input_range = c(0, 4095),
  full_range = FALSE,
  force_range = FALSE,
  gamma = 1
)

Arguments

mat

a finite numeric matrix.

input_range

a finite numeric vector of 2 values, sets the range of the input intensity values. Values exceeding this range are clipped. Default is c(0, 4095).

full_range

if 'full_range' is TRUE, then 'input_range' will be set to c(0, 4095) and 'gamma' forced to 1. Default is FALSE.

force_range

if 'force_range' is TRUE, then 'input_range' will be adjusted to object range in [-4095, +inf] and 'gamma' forced to 1. Default is FALSE. Note that this parameter takes the precedence over 'input_range' and 'full_range'.

gamma

gamma correction. Default is 1, for no correction.

Value

a [0,1] normalized matrix

Details

Note that negative values are used internally for removal of unmasked objects.
