public interface RegionOrientation

Estimates the orientation of a region which is approximately circular. This is typically used to rotationally invariant scale/size dependent features.

Method Summary

Modifier and Type	Method and Description
double	compute(double c_x, double c_y) Computes the orientation of a region about its center.
void	setObjectRadius(double radius) Specifies the circle's radius that the orientation should be

Method Detail

setObjectRadius

void setObjectRadius(double radius)

Specifies the circle's radius that the orientation should be

Parameters:

radius - Object's radius.

compute

double compute(double c_x,
               double c_y)

Computes the orientation of a region about its center.

Parameters:

c_x - Center of the region in image pixels.

c_y - Center of the region in image pixels.

Returns:

Orientation in radians. Angle zero points along x-axis and pi/2 along y-axis.
