DiT for Text Detection

Fine-tuned models on FUNSD

We summarize the validation results as follows. We also provide the fine-tuned weights.

name	initialized checkpoint	detection algorithm	F1	weight
DiT-base-syn	dit_base_patch16_224_syn	Mask R-CNN	94.25	link
DiT-large-syn	dit_large_patch16_224_syn	Mask R-CNN	94.29	link

Usage

Data Preparation

Follow these steps to download and process the FUNSD. The resulting directory structure looks like the following:

│── data
│   ├── annotations
│   ├── imgs
│   ├── instances_test.json
│   └── instances_training.json

Training

The following command provide example to train the Mask R-CNN with DiT backbone on 8 32GB Nvidia V100 GPUs.

The config files can be found in configs.

bash

python train_net.py --config-file configs/mask_rcnn_dit_base.yaml --num-gpus 8 --resume MODEL.WEIGHTS path/to/model OUTPUT_DIR path/to/output

Evaluation

The following commands provide examples to evaluate the fine-tuned checkpoint of DiT-Base with Mask R-CNN.

bash

python train_net.py --config-file configs/mask_rcnn_dit_base.yaml --eval-only --num-gpus 8  --resume  MODEL.WEIGHTS path/to/model OUTPUT_DIR path/to/output
