Fill in a patch with a (perturbed) frontal face patch.

Parameters:

patch (POINTER(IplImage)) - a POINTER(IplImage) that points to a uint8 IplImage. The patch is filled after calling generate()
perturb_func (a function [optional]) - This function takes an ImageView corresponding to the current view that encapsulates the frontal face. You can perturb the view before it is warped to the patch. It also returns a tuple expressing the purturbed parameters. If None is given, no pertubation is made.

Format:

def perturb_func(iview, *args, **kwds)

Input:

iview: ImageView

a view encapsulating the frontal face, to be supplied by generate()

Output:

perturbed_theta: tuple

a tuple of parameters expressing how the transformation matrix is perturbed
other, arguments, or, keywords, - all passed to perturb_func, if it exists

Returns:

Class FrontalFaceGenerator
