Left panel: Impact of the regularization, b, and the variance of spectral distribution, T. When the regularization is low, T has an appreciable impact. However, when regularization is high, it has less impact. This figure supports the claims in the section on mathematical acceleration in which the T parameter is not needed. Right panel: The impact of hyperparameters on the performance of VEViD. Increasing b reduces the effect of the imaginary part to which it is added. As can be seen in Fig. 11, being inverted, the imaginary part is a bright image, and reducing its influence has the effect of exposure reduction. Increasing b pushes the bright pixels into the saturating region of the arctan where they are squashed. The gain parameter, G, has a similar effect
