Dataset Card for PosterErase

Dataset Summary

PosterErase is a poster text-erasing dataset released with Self-supervised Text Erasing with Controllable Image Synthesis. It contains high-resolution poster images with text regions and structured annotations for text-erasing research.

This Hugging Face version exposes the original train, validation, and test splits as parquet files. The validation and test splits include ground-truth erased poster images; the training split contains source posters and annotations only.

Supported Tasks and Leaderboards

PosterErase is intended for image-to-image text erasing and inpainting on graphic design posters. A model receives a poster image and text-region annotations, then predicts a poster with the text removed while preserving the surrounding visual design.

No public leaderboard is bundled with this Hugging Face dataset. Use the upstream paper and repository for the original training and evaluation protocol.

Languages

Poster text is primarily Chinese (zh).

Dataset Structure

Data Instances

Each row contains a poster image, the original relative image path, and parsed annotation fields. Validation and test rows also include gt_image.

Data Fields

• number (int32): Original numeric example identifier from the annotation file.
• path (string): Original relative path of the source poster image.
• image (Image): Source poster image with text.
• gt_image (Image, nullable): Ground-truth erased poster image. This field is populated for validation and test rows and is null for training rows.
• annotation.masks (list): Text mask bounding boxes with x1, x2, y1, and y2 integer coordinates.
• annotation.place.objs (list): Parsed text object metadata with text, size, and direction.
• annotation.place.texts (list): Parsed text placement and color metadata. Each text item contains x, y, and cs; each color has c1, c2, and c3 integer channels.

Dataset Creation

Source Data

The original data was released by alimama-creative for the PosterErase text-erasing task. The original distribution uses six zip files named erase_1.zip through erase_6.zip.

Annotations

The loader parses the upstream tab-separated annotation files:

• train.txt for the training split.
• ps_valid.txt for the validation split.
• ps_test.txt for the test split.

The validation and test annotation files include a gt_path column that points to the ground-truth erased image.

Personal and Sensitive Information

The dataset contains poster images and rendered text from the upstream release. The dataset card does not identify personal information in the annotations, but posters may contain names, brands, faces, or culturally specific visual/textual content.

Considerations for Using the Data

Social Impact of Dataset

PosterErase can support better text erasing and design editing systems for poster images. It should be used with care when editing copyrighted, branded, or identity-bearing poster content.

Discussion of Biases

The dataset is centered on Chinese poster designs from the upstream release. Models evaluated on this dataset may not generalize to other writing systems, design cultures, poster genres, or typography styles.

Other Known Limitations

The training split does not include ground-truth erased images in this loader. The original task relies on the paper's self-supervised setup for training and uses validation/test ground truth for evaluation.

Additional Information

Dataset Curators

The original dataset was created by alimama-creative. This Hugging Face packaging is maintained by the creative-graphic-design project.

Licensing Information

The upstream Tianchi page has shown conflicting license indicators: the page text has stated CC BY-SA 4.0, while the page license selector has appeared to indicate a non-commercial ShareAlike Creative Commons license. This dataset card uses the more restrictive cc-by-nc-sa-4.0 metadata and users should verify the current upstream terms before redistribution or commercial use.
