SurGe: Improved Surface Geometry in Point Maps

SurGe is a feedforward 3D reconstruction method that predicts point maps and estimates global 3D geometry. It addresses inaccuracies in local surface geometry through a point gradient matching loss and a Neighborhood Attention Decoder (NAD) that progressively upsamples features and uses Neighborhood Attention for local feature mixing.

Usage

SurGe expects image tensors in BCHW format with unnormalized RGB values in [0, 1]. Do not apply ImageNet normalization or similar preprocessing.

import torch
from surge import SurGe

# Load model
model = SurGe.from_pretrained("karimknaebel/surge-large").eval().cuda()

# Prepare input
image = torch.rand(1, 3, 518, 518, device="cuda")

# Inference
result = model.infer(image, num_tokens="max")
points = result["points"]          # (B, H, W, 3)
depth = result["depth"]            # (B, H, W)
intrinsics = result["intrinsics"]  # (B, 3, 3)

num_tokens controls the encoder token budget. Use "min", "max", or an integer value.
