* The formula used to compute these coefficients is as follows:
*
- * \f$ g(x,y) = \epsilon^{-\pi((a(x cos(\theta)+y sin(\theta))^{2} +(b( y cos(\theta}-x sin(\theta))^{2})}*cos(2*\pi(u_{0}*x + v_{0}*y)+\phi) \f$
+ * \f$ g(x,y) = \exp\Big(-\pi((a x_\theta)^{2} +(b y_\theta)^{2})\Big) * \cos\big(2\pi(u_0*x + v_0*y)+\phi\big) \f$
+ *
+ * with:
+ *
+ * \f$ x_\theta = x \cos(\theta)+y \sin(\theta) \f$
+ * and
+ * \f$ y_\theta = y \cos(\theta)-x \sin(\theta) \f$

*
- * Radius : Radius of the generated filter (GetRadius()/SetRadius())
- * \f$ a \f$ : Scale the x axis of the gaussian envelop. (GetA()/SetA())
