Enum TrackStatus 

pub enum TrackStatus {
    Tracked,
    OutOfBounds,
    Diverged,
    LowTexture,
    FbInconsistent,
}

Why a feature point ended up where it did after tracking.

See TrackResult for the coordinate convention.

Variants

Tracked

The iteration converged inside the image; the position is trustworthy.

OutOfBounds

The search window left the image (in the previous or the next frame).

Diverged

The iteration hit max_iterations without converging (see CONVERGENCE_EPSILON), or a step exploded (non-finite or larger than the window). The reported position is the last estimate, not a lost track: callers that prefer OpenCV’s semantics may still use it.

LowTexture

The minimum eigenvalue of the spatial gradient matrix fell below the configured threshold, i.e. the window is too flat to track reliably.

FbInconsistent

The point was tracked forward, but re-tracking it back to the previous frame did not return close enough to the original position. Only produced by calc_optical_flow_fb. A strong occlusion/outlier signal.
