Struct EventFrame 

pub struct EventFrame { /* private fields */ }

Implementations

impl EventFrame

pub fn connected_components( &self, connectivity: u8, ) -> Result<EventFrame, ClusterError>

Labels 4- or 8-connected foreground components. connectivity must be 4 or 8. The result is a single-channel u64 frame the same size as self: 0 is background, and each component gets a distinct label in scan order starting at 1.

impl EventFrame

pub fn resize( &self, width: usize, height: usize, pooling: PoolingMethod, ) -> Result<Self, ResizeError>

Returns a resized frame, pooling shrinking axes and interpolating growing axes.

impl EventFrame

pub fn intensity( data: EventFrameData, width: usize, height: usize, ) -> Result<Self, RepresentationError>

Builds a single-channel greyscale frame from raw samples, row-major.

The public counterpart to EventFrame::from_parts, which is crate-private and validates nothing — so this is the only way anything outside the core (the bindings, the video decoder) can construct a frame, and it checks the length rather than trusting the caller. Everything downstream indexes c * width * height + y * width + x and would read out of bounds on a mismatch.

pub fn data(&self) -> &EventFrameData

pub fn into_data(self) -> EventFrameData

Takes the frame’s samples, for a caller that owns the frame and wants the buffer rather than a copy of it — handing a just-generated frame straight to numpy, say.

pub fn shape(&self) -> (usize, usize, usize)

pub fn channel_names(&self) -> &[String]

pub fn kind(&self) -> RepresentationKind

Trait Implementations
