Adds KeyPoint data structure with floating point coordinates.
The structure is similar to standard vx_keypoint_t
, but it uses floating point coordinates instead of integer.
Data Fields |
vx_float32 |
x |
Holds the x coordinate. |
vx_float32 |
y |
Holds the y coordinate. |
vx_float32 |
strength |
Holds the strength of the keypoint. Its definition is specific to the corner detector. |
vx_float32 |
scale |
Holds the scale initialized to 0 by corner detectors. |
vx_float32 |
orientation |
Holds the orientation initialized to 0 by corner detectors. |
vx_int32 |
tracking_status |
Holds tracking status. Zero indicates a lost point. Initialized to 1 by corner detectors. |
vx_float32 |
error |
Holds a tracking method-specific error. Initialized to 0 by corner detectors. |
