Gaussian Distortion

• Grid width and height, and magnitude are kept the same as the random distortion values of 6, 6, and 5, respectively
• The Gaussian distortion has the added parameters of applying the distortion based on the 2D normal distribution
• normal distortion is applied to each grid point on a circular surface (corner=“bell”) and with default values for the mean and standard deviation (${\mu }_x$ = ${\mu }_y$ = 0.5,${\sigma }_x$ = ${\sigma }_y$ = 0.05)
• $p(x,y)=exp\{-(\frac{(x-{\mu }_x{)}^2}{{\sigma }_x}+\frac{(x-{\mu }_y{)}^2}{{\sigma }_y}))\}$
