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, or a step exploded (non-finite or larger than the window).

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.

Trait Implementations

impl Clone for TrackStatus

fn clone(&self) -> TrackStatus

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TrackStatus

impl Debug for TrackStatus

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for TrackStatus

impl PartialEq for TrackStatus

fn eq(&self, other: &TrackStatus) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
