"WebGamma correction is, in the simplest cases, defined by the following power-law expression: where the non-negative real input value is raised to the power and multiplied by the constant A to get the output value . In the common case of A = 1, inputs and outputs are typically in the range 0–1. A gamma value is sometimes called an encoding gamma ... " - Opencv auto gamma correction
