LSVT Dataset¶

Data Downloading¶

The LSVT dataset Official Website | Download Link

Note: Please register an account to download this dataset.

The images are split into two zipped files train_full_images_0.tar.gz and train_full_images_1.tar.gz. Both are to be downloaded. After downloading the images as above, unzip them and collect them into a single folder e.g. train_images.

The LSVT annotations (in JSON format) can be downloaded from this download link. The file train_full_labels.json needs to be downloaded.

After downloading the images and annotations as above, the directory structure should be like as follows (ignoring the archive files):

LSVT
  |--- train_images
  |    |--- gt_0.jpg
  |    |--- gt_1.jpg
  |    |--- ...
  |--- train_full_labels.json

Data Preparation¶

For Detection Task¶

To prepare the data for text detection, you can run the following commands:

python tools/dataset_converters/convert.py \
    --dataset_name lsvt --task det \
    --image_dir path/to/LSVT/train_images/ \
    --label_dir path/to/LSVT/train_full_labels.json \
    --output_path path/to/LSVT/det_gt.txt

The generated standard annotation file det_gt.txt will now be placed under the folder LSVT/.
