gma.math.correction.gamma

[function] gamma(data, constant = 1, ignore_value = None, gamma_v = 1):

Gamma transform. Reference equation: Out = constant * ((data - vvmin) / vptp) ** gamma_v) * vptp.

Parameters:

data: array.

The data to be corrected.

**Optional:

constant = float. Default 1.

The constant term of the correction factor.

ignore_value = float||None. Default None.

The value that is not involved in the calculation.

gamma_v = float. Default 1.

Gamma value.

**Note:

If the input data type is uint8, the data will be transformed between 0 ~ 255.

Otherwise, it will transform between the maximum and vminimum values of the input array.

Returns:

Type: array.
