File	Description
`GSD.pth`	GlassNet weights trained on the GSD training split

Usage

python

import torch
from huggingface_hub import hf_hub_download
from model import GlassNet

ckpt = hf_hub_download("garrying/GSD-GlassNet", "GSD.pth")
net = GlassNet()
net.load_state_dict(torch.load(ckpt, map_location="cpu"))
net.eval()

For full inference code (data loading, CRF post-processing, saving outputs) see infer.py in the original release.

Model Architecture

GlassNet uses a ResNeXt-101 backbone with:

DenseContrastModule — multi-scale dilated convolutions (rates 1/2/4/8) with pairwise feature subtraction to capture cross-context contrast
SELayer — grouped squeeze-and-excitation for context-aware channel reweighting
RefNet — a lightweight U-Net-style decoder that jointly predicts the binary glass mask and reconstructs the reflection image as auxiliary output
CRF post-processing — dense CRF refinement of predicted masks at inference time

Dataset

The GSD dataset is available at garrying/GSD.
