Detailed Description

*Overlapping circular receptive fields technique

*The Cartesian plane is divided in two regions: the fovea and the periphery. *The fovea (oversampling) is handled by using the bilinear interpolation technique described above, whereas in *the periphery we use the overlapping Gaussian circular RFs.

*More details can be found in http://dx.doi.org/10.1007/978-3-642-23968-7_5

Constructor & Destructor Documentation

cv::LogPolar_Overlapping::LogPolar_Overlapping

(

)

cv::LogPolar_Overlapping::LogPolar_Overlapping	(	int	w,
		int	h,
		Point2i	center,
		int	R = 70,
		double	ro0 = 3.0,
		int	full = 1,
		int	S = 117,
		int	sp = 1
	)

    *Constructor

Parameters:

w	the width of the input image
h	the height of the input image
center	the transformation center: where the output precision is maximal
R	the number of rings of the cortical image (default value 70 pixel)
ro0	the radius of the blind spot (default value 3 pixel)
full	1 (default value) means that the retinal image (the inverse transform) is computed within the circumscribing circle. 0 means that the retinal image is computed within the inscribed circle.
S	the number of sectors of the cortical image (default value 70 pixel). Its value is usually internally computed to obtain a pixel aspect ratio equals to 1.
sp	1 (default value) means that the parameter S is internally computed. 0 means that the parameter S is provided by the user.
