Dataset Overview
Definition：Colposcopy and Cervicoscopy Endoscopy Video Datasetis provided byChangsha Langhui Information Technology Co., Ltd.The large-scale vulcanography survey image a database, constructed by Long Salang Langhui Information Technology, Ltd., is designed to record the full time series of time series images following the cervical and vaginal sectional acetic anhydride test, to retain the equipment to export the original full inspection video and key original maps, along with CIN grade (LSIL/HSIL), the beaurate region label, the results of the iodine test and HPV detection correlation data.

Delivery Specifications and Field Requirements
The data set strictly follows the ENDO-COLPO uniform delivery index requirements to ensure data quality and traceability.
Delivery & Counting：One full vaginal lens check per row; one multi-series/multi-view only
Coverage：Complete time-series multiple images of the cervix and vaginal sectional acetic acid test (60/90/1500.180 seconds)
Positives and Composition：CIN I/II/III and leaching cancer stratification; suspected, not except for pathological diagnosis
Time series notation:Aceto-white changes are annotated as a time series, supporting the training of temporal attention models
Cross-Data Association：Must relate to official vaginal lens reports; priority to be given to cervical pathology, HPV testing, cytology
2026 Frontier AI Research Progress
Domain Review：In 2025-2026, vaginal mirror AI made progress in time series multi-frame integration (TLS-Net, Scientific Reports 2026) and multi-equipment extension, with Smart Spope AI being 93.46 per cent specific as a POC screening tool.
TLS-Net time series vaginal lense partition
Scientific Reports, 2026Using the Swin Transformer encoder and time-series attention module, the integration of 60/90/1500.180 seconds of white acetate images is achieved to achieve a precise partition of the cervical-crystals stove area.
Automatic multi-equipment vaginal/alcoscope pre-cancer cancer detection
2025320 tests (3 equipment types), CNN classified lower (LSIL) and higher (HSIL) gill-like internal pathologies.
Smart Spope AI POC Screening Scrutinization
Cureus, 2024Smart Spope AI 93.46%, AUC 0.73 (95% CI: 0.60-0.86), Sensitivity 52.17% as a prompt screening diversion tool.
U-NET++ and RepVGG Early detection of cervical cancer
Frontiers in Oncology, 2025The model, with a forecast accuracy rate of 83.01 per cent in 424 cases, has a better ability to identify early CIN I and CIN II pathologies.
Annotation Workflow & Quality Control
Image Acquisition & De-identification
Standardized acquisition workflow: complete data is exported directly from the equipment, and patient identifying information (PHI) is removed before the data is stored。
Initial Annotation (Specialist Physician)
Attending physicians annotate case by case against the standards, including lesion localization, morphological description and disease term determination。
Review (Associate Chief Physician or Above)
Experts with the title of Associate Chief Physician or above review the initial annotation results item by item, correcting erroneous annotations and supplementing missing dimensions。
Consistency Assessment
10% of samples are randomly selected and independently annotated by 3 physicians to calculate Fleiss' Kappa; below 0.Dimensions scored 75 are flagged for rework。
