Detailed Description
2D edge feature structure
Member Data Documentation
| | 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. | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| | covariance of feature edge in direction given by the orientation field (angle) | | --------------------------------------------------------------------------------- |
| | potentially sub-pixel coordinates of edge feature in coordinate frame defined by edge map | | -------------------------------------------------------------------------------------------- |
