Visual Token Matching

(Update 08/23, 2023) We have uploaded pretrained checkpoints in this link. Meta-trained checkpoints for each fold are included in TRAIN directory, and fine-tuned checkpoints for each task (and each channel) are included in FINETUNE directory.

(News) Our paper received the Outstanding Paper Award in ICLR 2023!

This repository contains official code for Universal Few-shot Learning of Dense Prediction Tasks with Visual Token Matching (ICLR 2023 oral).

Setup

1. Download Taskonomy Dataset (tiny split) from the official github page https://github.com/StanfordVL/taskonomy/tree/master/data.

• You may download data of depth_euclidean, depth_zbuffer, edge_occlusion, keypoints2d, keypoints3d, normal, principal_curvature, reshading, segment_semantic, and rgb.
• (Optional) Resize the images and labels into (256, 256) resolution.
• To reduce the I/O bottleneck of dataloader, we stored data from all buildings in a single directory. The directory structure looks like:

<root>
|--<task1>
|   |--<building1>_<file_name1>
|   | ...
|   |--<building2>_<file_name1>
|   |...
|
|--<task2>
|   |--<building1>_<file_name1>
|   | ...
|   |--<building2>_<file_name1>
|   |...
|
|...

2. Create data_paths.yaml file and write the root directory path (<root> in the above structure) by taskonomy: PATH_TO_YOUR_TASKONOMY.

3. Install pre-requirements by pip install -r requirements.txt.

4. Create model/pretrained_checkpoints directory and download BEiT pre-trained checkpoints to the directory.

• We used beit_base_patch16_224_pt22k checkpoint for our experiment.

Usage

Training

python main.py --stage 0 --task_fold [0/1/2/3/4]

Fine-tuning

python main.py --stage 1 --task [segment_semantic/normal/depth_euclidean/depth_zbuffer/edge_texture/edge_occlusion/keypoints2d/keypoints3d/reshading/principal_curvature]

Evaluation

python main.py --stage 2 --task [segment_semantic/normal/depth_euclidean/depth_zbuffer/edge_texture/edge_occlusion/keypoints2d/keypoints3d/reshading/principal_curvature]

After the evaluation, you can print the test results by running python print_results.py
