@ -12,8 +12,8 @@ For the distortion OpenCV takes into account the radial and tangential factors.
.. math::
x_{corrected} = x( 1 + k_1 r^2 + k_2 r^4 + k^3 r^6) \\
y_{corrected} = y( 1 + k_1 r^2 + k_2 r^4 + k^3 r^6)
x_{corrected} = x( 1 + k_1 r^2 + k_2 r^4 + k_3 r^6) \\
y_{corrected} = y( 1 + k_1 r^2 + k_2 r^4 + k_3 r^6)
So for an old pixel point at :math:`(x,y)` coordinate in the input image, for a corrected output image its position will be :math:`(x_{corrected} y_{corrected})` . The presence of the radial distortion manifests in form of the "barrel" or "fish-eye" effect.
