TwoWayTransformer

oxicuda_vision::segmentation::sam

Struct TwoWayTransformer 

Source 
pub struct TwoWayTransformer { /* private fields */ }
Expand description

Stacks several TwoWayAttentionBlocks, followed by a final token→image attention as in SAM’s TwoWayTransformer.

Implementations§

Source§

impl TwoWayTransformer

Source

pub fn forward( &self, image: &[f32], image_pe: &[f32], point_tokens: &[f32], ) -> VisionResult<(Vec<f32>, Vec<f32>)>

Run the transformer. image/image_pe are [n_i · e], point_tokens is [n_t · e]. The point tokens double as the query positional encoding, exactly as in SAM.

Returns (tokens [n_t · e], image [n_i · e]).

§Errors

Propagates block / attention errors.
