Memory-encoder configuration. Mirrors sam2/modeling/memory_encoder.py::MemoryEncoder + its MaskDownSampler and Fuser. Defaults match every published sam2_hiera_*.yaml memory_encoder: block.

Fields

in_dim: usize

Input feature dim from the FpnNeck stride-16 level.

out_dim: usize

Output memory token dim (smaller than in_dim in published configs: 64 vs 256, so memory bank tokens are cheap to store).

mask_downsampler_kernel: usize

MaskDownSampler: per-step kernel/stride/padding + total stride. total_stride must be a power of stride; reference uses kernel=3 stride=2 padding=1 total=16 → 4 down-sampling levels.

mask_downsampler_stride: usize

mask_downsampler_padding: usize

mask_downsampler_total_stride: usize

fuser_num_layers: usize

Fuser: num_layers × CXBlock(dim, kernel, padding, ls_init).

fuser_dim: usize

fuser_kernel: usize

fuser_padding: usize

fuser_layer_scale_init_value: f32

fuser_use_dwconv: bool

fuser_input_projection: bool

pe_num_pos_feats: usize

Memory-encoder output PE: num_pos_feats * 2 is the channel count of the emitted position encoding.

pe_temperature: f32
