Struct FlowField 

pub struct FlowField {
    pub width: u32,
    pub height: u32,
    pub vectors: Vec<FlowVector>,
}

Dense optical flow field.

Contains one FlowVector per pixel of the image.

Fields

width: u32

Width of the source image.

height: u32

Height of the source image.

vectors: Vec<FlowVector>

Per-pixel flow vectors in row-major order.

Implementations

impl FlowField

pub fn zeros(width: u32, height: u32) -> Self

Create a zero-initialised flow field.

pub fn get(&self, x: u32, y: u32) -> Option<FlowVector>

Get the flow vector at pixel (x, y), or None if out of bounds.

pub fn mean_magnitude(&self) -> f32

Compute the mean magnitude of all flow vectors.

pub fn warp_frame(&self, target: &[u8]) -> Result<Vec<u8>>

Warp the target frame backwards using this flow field to produce a motion-compensated intermediate frame.

For each output pixel p, samples target[p - flow(p)] using bilinear interpolation. Pixels that map outside target are filled with black (zero).

Arguments

• target – RGBA pixel data for the frame to warp.

Errors

Returns an error if target does not match the flow field dimensions.

Trait Implementations

impl Clone for FlowField

fn clone(&self) -> FlowField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlowField

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

Formats the value using the given formatter.
