Calculates an affine transformation that normalize given image using Pei/Lin Normalization

T = cv.PeiLinNormalization(I)

Input

• I Given transformed image.

Output

• T 2x3 transformation matrix corresponding to inversed image transformation.

Assume given image I = T(Ibar) where Ibar is a normalized image and T is an affine transformation distorting this image by translation, rotation, scaling and skew. The function returns an affine transformation matrix corresponding to the transformation T_inv described in [PeiLin95]. For more details about this implementation, please see [PeiLin95].
