ReDiCo: Relay-Mediated Visual Updating for 3D Referring Segmentation

Official pretrained checkpoints for ReDiCo, a 3D Referring Expression Segmentation (3D-RES / 3D-GRES) method.

Code | Paper

Model Description

ReDiCo iteratively refines query-point features through relay-mediated visual updating, jointly modeling geometric relations, coverage, and diversity of the assigned points for 3D referring expression segmentation.

Two checkpoints:

File	Task	Dataset
redico_res.pth	3D-RES	ScanRefer
redico_gres.pth	3D-GRES	Multi3DRefer

Metrics (val)

Task	Dataset	mIoU	Acc@0.5	Acc@0.25
3D-RES	ScanRefer	51.7	57.1	62.7
3D-GRES	Multi3DRefer	53.7	54.1	73.8

Usage

# clone code
git clone https://github.com/songchuanle-1/ReDiCo.git
cd ReDiCo

# download checkpoints
wget https://huggingface.co/chuanle/ReDiCo/resolve/main/redico_res.pth
wget https://huggingface.co/chuanle/ReDiCo/resolve/main/redico_gres.pth

# inference — 3D-RES (ScanRefer)
python tools/test.py configs/redico.yaml --checkpoint redico_res.pth --gpu_ids 0 --out ./output

# inference — 3D-GRES (Multi3DRefer)
python tools/test.py configs/redico_gres.yaml --checkpoint redico_gres.pth --gpu_ids 0 --out ./output

Data and pretrained backbone (sp_unet_backbone.pth) download links are in the GitHub repo README (Baidu Netdisk mirror).
