Estimate Depth (Marigold)

Diffusion-based monocular depth estimator (Marigold) over each Image, emitting a deploy-time-resolved choice of an affine-invariant relative depth map or a greyscale depth Image. The depth is scale- and shift-invariant relative depth, never metric.

Decompose Intrinsic Image (Marigold)

Marigold diffusion intrinsic-image decomposer: takes an Image and emits a single Image layer — the view-independent albedo (reflectance) or the packed BRDF material map (roughness in red, metallicity in green) — at the input resolution.

Estimate Surface Normals (Marigold)

Diffusion-based monocular surface-normal estimator (Marigold) over each Image, emitting a deploy-resolved choice of a dense per-pixel SurfaceNormalMap (camera-space unit normals) or a normals-to-RGB visualisation Image.
