* @brief Calculates an affine transformation that normalize given image using Pei&Lin Normalization. |
|
* |
|
* Assume given image \f$I=T(\bar{I})\f$ where \f$\bar{I}\f$ is a normalized image and \f$T\f$ is an affine transformation distorting this image by translation, rotation, scaling and skew. |
|
* The function returns an affine transformation matrix corresponding to the transformation \f$T^{-1}\f$ described in [PeiLin95]. |
|
* For more details about this implementation, please see |

* @param I Given transformed image. |
