EANJ_FACE_26: 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_26), 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.

3. Data Description

3.1 Object Information

Human-face morphology jade object (single specimen)

Approximate measurements:

Length: 11.9 cm

Width: 5.8 cm

Thickness: 0.4 cm

Weight: 61 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_26_OVERALL_A

EANJ_FACE_26_OVERALL_B

Macro views

EANJ_FACE_26_MACRO_A

EANJ_FACE_26_MACRO_E

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.
