KeyPoint Types

Detailed Description

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 Structures

Data Structure Documentation

struct nvx_keypointf_t
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.
