STFD Dataset
This folder contains the STFD (Screenshot Text Forgery Dataset) used in the paper:
Learning to Locate the Text Forgery in Smartphone Screenshots Zeqin Yu, Bin Li, Yuzhen Lin, Jinhua Zeng, Jishen Zeng ICASSP 2023

STFD is designed for text image forgery localization (T-IFL) in smartphone screenshots. The dataset contains tampered screenshots and their corresponding pixel-level forgery masks.

Each image in tamper/ has a corresponding mask with the same filename in masks/.
Example:
tamper/ffa3cedd4317633601c6fb82d94fc783.png
masks/ffa3cedd4317633601c6fb82d94fc783.png
The mask is a binary image, where:
- 0 = non-tampered region
- 255 = tampered region
Tampering Types
STFD contains five common screenshot text manipulation operations:
- Copy-Move: copy a text region and paste it to another location within the same image.
- Splicing: paste text regions from another image into the target image.
- Removal: remove existing text and fill the region using inpainting.
- Insertion: insert new text content into blank regions.
- Replacement: replace original text with newly generated text.
Screenshot Sources
The screenshots were captured from real devices to reflect realistic usage scenarios.
