Struct OpticalFlowTracker 

pub struct OpticalFlowTracker { /* private fields */ }

Available on crate feature tracking only.

Tracks dense optical flow across a frame sequence.

Implementations

impl OpticalFlowTracker

pub fn new(reference_path: impl AsRef<Path>) -> Result<Self, VisionError>

Create a new optical-flow tracker seeded with the reference image.

Errors

Returns VisionError if the image path is invalid, the image fails to load, or Vision rejects the tracking request.

pub fn track( &mut self, image_path: impl AsRef<Path>, ) -> Result<OpticalFlowFrame, VisionError>

Track optical flow into image_path and return the copied raw pixel-buffer bytes.

Errors

Returns VisionError if the image path is invalid, the image fails to load, or Vision rejects the tracking request.

Trait Implementations

impl Drop for OpticalFlowTracker

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
