The Leeds Skin Database - LSDB

The Leeds Skin Database (LSDB) offers a detailed collection of spectral and colorimetric data for human skin, encompassing 15,256 records from 2,113 subjects. This data spans from 2012 to 2024 and originates from eleven datasets curated by international laboratories in eight countries: the UK, Spain, China, Japan, Pakistan, Thailand, Iraq, and Saudi Arabia. Each dataset follows a standardised measurement protocol to maintain data consistency.In the LSDB, individual records provide extensive details including record number, data origin, subject identification, and skin type—categorised by ethnicity, gender, age, and body location. The database also includes detailed information on the measurement instruments used, such as type, specular component inclusion, wavelength range and interval.Alongside spectral data, each sample also contains CIE colorimetric data, including tristimulus values, xy chromaticity coordinates, CIELAB parameters, etc., based on the CIE 1931 standard colorimetric observer and the CIE standard illuminant D65.The database is organised into two primary spreadsheets: a coding scheme and a datasheet. The datasheet arranges data across columns labelled A to BQ:A: Unique record identifierB: Data origin (linked to an origin table in the coding scheme)C: Subject numberD to G: Ethnicity, gender, age group, and body location (each linked to respective reference tables in the coding scheme)H to L: Instrument details including type and spectral measurement specificsN to BD: Spectral data from 360 nm to 780 nmBF to BQ: CIE colorimetric dataNote: Not all columns contain data due to variations in the spectral range covered by different datasets.This structured format ensures that users can easily access and interpret data for diverse research applications.<br>Any use of the LSDB should cite the following reference: Lu, Yan; Xiao, Kaida; Pointer, Michael; He, Ruili; Zhou, Sicong; Nasseraldin, Ahmed; et al.

利兹皮肤数据库（Leeds Skin Database, LSDB）收录了详实的人体皮肤光谱与色度学数据，涵盖来自2113名受试者的15256条记录。该数据集的时间跨度为2012年至2024年，数据源自8个国家（英国、西班牙、中国、日本、巴基斯坦、泰国、伊拉克、沙特阿拉伯）的国际实验室所整理的11个子数据集。所有子数据集均遵循标准化测量规程，以保障数据一致性。
在LSDB中，单条记录包含丰富的详细信息，包括记录编号、数据来源、受试者标识以及按种族、性别、年龄和身体部位分类的皮肤类型。该数据库还收录了所用测量仪器的详细信息，包括仪器类型、是否包含镜面反射分量、波长范围与波长间隔。
除光谱数据外，每条样本还包含基于国际照明委员会（CIE）1931标准色度观察者与CIE标准照明体D65的CIE色度学数据，包括三刺激值、xy色度坐标、CIELAB色彩空间参数等。
该数据库分为两个主要电子表格：编码方案表与数据集工作表。数据集工作表按列排布数据，列标识从A至BQ：
A：唯一记录标识符
B：数据来源（关联至编码方案表中的来源表）
C：受试者编号
D至G：种族、性别、年龄组与身体部位（各字段均关联至编码方案表中的对应参考表）
H至L：仪器详情，包括仪器类型与光谱测量具体参数
N至BD：360 nm至780 nm波段的光谱数据
BF至BQ：CIE色度学数据
注：由于不同子数据集覆盖的光谱范围存在差异，并非所有列均包含有效数据。
这种结构化格式可帮助用户便捷地获取并解读数据，适用于各类科研应用场景。
