Struct FeaturePyramidNeck 

pub struct FeaturePyramidNeck { /* private fields */ }

Feature Pyramid Network neck: upsamples and concatenates multi-scale features from the backbone into a unified feature map at the first scale.

Implementations

impl FeaturePyramidNeck

pub fn new(out_channels: usize) -> Self

Create a new FPN neck that maps all backbone scales to out_channels.

pub fn forward( &self, scales: &[(Array2<f64>, usize, usize)], ) -> Result<(Array2<f64>, usize, usize)>

Fuse multi-scale features.

Takes the three feature maps from SimpleBEVBackbone::forward and returns a single (H1*W1, out_channels) feature map at the first backbone scale.
