EANJ_FACE_05: Low-Resolution Visual Record of a Human-Face Morphology Jade Object (Public Preview)

1. Dataset Context This dataset is part of a systematic digital visual archiving project. It contains low-resolution, multi-view visual documentation of a single human-face morphology jade object (EANJ_FACE_05), and is published as the public preview layer within a structured multi-tier dataset framework. 2. Research Purpose This dataset is generated through standardized imaging and documentation procedures to provide a verifiable baseline of visual data. It supports research conducted under user-defined methodological frameworks, including: Morphological comparative studies Teaching and illustrative purposes Non-invasive image-based analysis The low-resolution images are intended for public preview only.The corresponding high-resolution original dataset (approximately 42 megapixels per image) is published as a separate record (Record B) under restricted access. Access requests are submitted via the following DOI:https://doi.org/10.5281/zenodo.18665122 3. Data Description 3.1 Object Information Human-face morphology jade object (single specimen) Approximate measurements: Length: 7.0 cmWidth: 2.9 cmHeight: 1.4 cmWeight: 25 g Note: These values are derived from imaging-based measurements and are provided as reference only. They do not constitute precise metrological data. 3.2 Image Content The low-resolution public preview includes four representative images selected for structural identification and general visual reference: Overall views EANJ_FACE_05_FRONTEANJ_FACE_05_REVERSE Macro views EANJ_FACE_05_MIC_FRONT_ONP_LEANJ_FACE_05_MIC_REVERSE_WEAR This preview represents a subset of the full dataset.The complete high-resolution Record B contains additional viewing angles and more detailed visual documentation. 3.3 Imaging Method Equipment: Full-frame digital camera with 90 mm macro lensFormat: RAW capture → JPEG export for publicationLighting: Controlled lighting environmentBackground: Neutral backgroundPhysical intervention: NonePost-processing: Global exposure and white balance adjustments only 4. Data Access & Structure This dataset follows a tiered publication structure: Record A: Low-resolution public preview (this record) Record B: High-resolution original imagery (restricted access) This structure distinguishes between public-facing visual materials and research-grade datasets. 5. Usage & Licensing This dataset is intended for academic research, teaching purposes, and non-interpretive visual comparative analysis. Any use beyond these purposes, including commercial use, redistribution, or non-academic dissemination, requires prior authorization. 6. Notes on Interpretation This dataset provides only directly observable visual information. It does not contain any interpretive, classificatory, or historical claims. 7. Access Information The full high-resolution dataset (Record B) is published as a separate record under restricted access.
