    * Given (x,y) the coordinates of a point in cartesian system, the corresponding
    * log-polar coordinates are :
-   * Rho = 1/2*log((x-xc)²+(y+yc)²)
-   * Theta = asin(y-yc)/(sqrt((x-xc)²+(y+yc)²))
+   * \f$ \rho = 1/2*log((x-xc)^2+(y+yc)^2) \f$
+   * \f$ \theta = asin(y-yc)/(\sqrt{(x-xc)^2+(y+yc)^2}) \f$
    *
    * In this implemenatation, theta is expressed in degree, and the result of the asin function
    * is clamped to the [0,360] range. Please note that since the transform of the center has no meaning
