Finds all circles in an image.

Parameters:

[in]	src	Image on wich processing the algorithm to find circles.
[in]	Tl_x	Starting x of the roi.
[in]	Tl_y	Starting y of the roi.
[in]	_Tp_width	Width of the roi (s.t. end x of the roi is Tl_x + _Tp_width).
[in]	_Tp_height	Height of the roi (s.t. end x of the roi is Tl_y + _Tp_height).
[in]	sigma	Parameter of smoothing for Gaussian blur.
[in]	thresh	Value of the threshold for thresholding.
[in]	max_val	Value put as maximum value in thresholding.
[in]	type	Type of applied threshold.
[in]	area_circ_min	Minimum area of a circle.
