is a specialized dataset used for developing and benchmarking computer vision algorithms for mobile identity document (ID) recognition. It is part of the Mobile Identity Document Video (MIDV)
series, which provides researchers with realistic video data of identity documents captured on mobile devices. Overview of MIDV-661 While earlier datasets like
focused on a wide variety of global document types, MIDV-661 expands upon these benchmarks by addressing specific technical challenges in automated ID verification. Primary Purpose: To serve as a high-quality resource for research in identity document analysis
, particularly for text field extraction, face detection, and geometric document localization within video streams. Key Features:
It typically includes video clips captured via smartphones, featuring a range of identity documents (such as passports and ID cards) under varying lighting conditions, backgrounds, and angles. Privacy & Safety:
To avoid privacy violations, the dataset uses documents that are either in the public domain or have been synthetically generated to include artificial faces, signatures, and text field data. Technical Significance
MIDV-661 is critical for training and testing "Green Lane" or "fast-track" check-in systems, where a user takes a video of their ID for instant verification. It allows developers to measure: OCR Precision:
How accurately the system extracts text from different document field types. Face Verification Accuracy:
The ability to match the photo on an ID to a live "selfie" video with high Rank-1 identification rates. Robustness:
The system's performance against localization errors or "presentation attacks" (e.g., trying to use a photo of a screen instead of a physical document). Researchers often use this dataset alongside others like
