radius_sp

Spatial filter radius (voxels).

eps_sp

Spatial regularization (variance floor).

radius_t

Temporal filter radius (frames).

eps_t

Temporal regularization.

guide_spatial

Optional 3D spatial guide.

guide_temporal

Optional length-T temporal guide.

motion_params

Optional T×(3 or 6) motion regressors; used to weight temporal guidance.

sigma_m

Motion weight scale (frames).
