Detailed Description

2D edge feature structure


Member Data Documentation

float Gan_EdgeFeature::angle
 

orientation of edge in radians, where applicable.

The angle is measured from the positive x axis (zero) towards the positive y axis (pi/2), and should be in the range [-pi,pi]. The angle should point in the direction of higher image intensity, or a suitably analagous direction.

float Gan_EdgeFeature::cov
 

covariance of feature edge in direction given by the orientation field (angle)

Gan_Vector2_f Gan_EdgeFeature::p
 

potentially sub-pixel coordinates of edge feature in coordinate frame defined by edge map
