Midv260 Upd ((full))

The MIDV-UP (Mobile Identity Document Video – Update/UP) dataset is a significant expansion of the Mobile Identity Document Video (MIDV) series, specifically designed to address the geographic and technical gaps in identity document analysis. While earlier versions like MIDV-500 and MIDV-2020 focused heavily on European and simulated documents, the MIDV-UP update introduces a more diverse set of real-world document samples, primarily from Pakistani and Iranian jurisdictions. Core Purpose and Evolution

The primary goal of the MIDV series is to provide researchers with high-quality, annotated video data to train and test algorithms for:

Document Detection: Identifying the presence and boundaries of an ID within a camera's field of view.

OCR (Optical Character Recognition): Extracting text from dynamic video streams, which is more challenging than static scans due to motion blur and lighting shifts.

Anti-Spoofing: Detecting holograms or physical manipulations used in identity fraud. Technical Characteristics

The MIDV-UP update follows the rigorous data structure established by its predecessors, ensuring compatibility for comparative research.

Environmental Variability: Like the MIDV-Holo branch, the "UP" update includes footage captured under various conditions: office lighting (Condition A/B), mobile flashlight (Condition C/D), and natural outdoor lighting (Condition E). midv260 upd

Hardware Diversity: The data is typically captured using a range of mobile devices, such as the iPhone 12, Samsung S10, and older models like the iPhone XR, to ensure models can generalize across different camera sensors.

Annotation Quality: Each frame is meticulously annotated with document boundary quadrangles (four-point coordinates) and unique document identifiers, often in JSON format compatible with tools like VGG Image Annotator. Impact on Document Forensics

By incorporating documents from Pakistan and Iran, MIDV-UP addresses the "domain shift" problem where AI models trained on Latin-alphabet documents fail when encountering different scripts (Arabic, Urdu, Persian) or unique security features. This update is crucial for developing robust, globally-applicable remote identity verification systems, which have seen increased demand in the digital banking and telecommunications sectors.

Researchers can find relevant dataset documentation and metadata on platforms like ResearchGate and GitHub to support further development in document-oriented computer vision. SmartEngines/midv-holo - GitHub

1. Parameter Set Updates (PSP)

Older MIDV versions required parsing the Sequence Parameter Set (SPS) and Picture Parameter Set (PPS) only at the beginning of the stream. The UPD allows these parameter sets to be refreshed dynamically mid-stream. This is vital for live broadcasting where the color space might shift mid-recording (e.g., switching between HDR and SDR feeds).
