资源简介:

This dataset contains manually annotated bounding boxes around the logos of 40 Bangladeshi news outlets as they appear on social media news photocards — square image-based news summaries distributed primarily on Facebook. It was created to support the development and evaluation of a multi-layer forensic pipeline for news photocard verification. The dataset comprises 800 original photocards collected from the official Facebook pages of each outlet, annotated with logo-only bounding boxes in YOLOv8 format. After augmentation in Roboflow (horizontal flip, brightness ±15%, blur ≤1px, 3x multiplier), the dataset contains 1,915 images split 70/20/10 into train/valid/test. The 40 outlets span both broadcast television and print media, covering major Bengali-language and English-language publications. A YOLOv8n model trained on Version 2 of this dataset achieved a test-set mAP@50 of 0.9936 across 40 classes. This dataset was produced as part of the undergraduate thesis:"Multi-Layer Forensic Verification of Bangladeshi News Photocards Using Deep Learning and OCR-Based Content Cross-Referencing"Bangladesh University of Professionals, 2026. Note: Images were collected from publicly accessible Facebook pages for non-commercial academic research purposes. Images remain the intellectual property of their respective news organizations.
