Figaro-tresses: a dataset for evaluating hair assembly features before and after cosmetic treatment (v2020)

The published database is composed of 1,080 images taken from 120 hair tresses made of medium blond, fine Caucasian hair with the aim to facilitate quantitative and qualitative studies about shampoo and conditioner efficacies. Two types of hair tresses were used: Caucasian hair which had not been subjected to oxidation with bleaching agents – virgin (60 tresses); and Caucasian hair, previously subjected to light oxidative bleaching – lightly bleached (remaining 60 tresses). Since cosmetic products such as shampoos and conditioners are often designed to subtly augment hair assembly features via the carefully balanced cumulative effects of deposited actives, each tress was subjected to consecutive washing+conditioning+drying cycles referred to as cosmetic treatment. The shampoo and conditioner used for this project were specifically selected for their suitability for fine hair. Each tress was photographed at three different time points: before the cosmetic treatment; after two cosmetic treatments, and after an additional third cosmetic treatment. At each timepoint, each tress was photographed from three different angles (-45, 0, and +45 degrees), resulting in a total number of nine images for each tress. For each image in the database, we also provide a corresponding hair segmentation mask, which identifies the hair location area in the original image.

本发布之数据库由来自120根中等色调的淡黄色细质白种人头发发束的1,080张图像组成，旨在促进洗发水和护发素功效的定量与定性研究。研究采用了两种类型的发束：未经漂白剂氧化处理的原生白种人头发（60根发束）；以及先前经过轻微氧化漂白处理的白种人头发（剩余60根发束）。鉴于化妆品如洗发水和护发素通常通过精心平衡的累积活性物质的沉积效应，微妙地增强头发结构特征，每根发束均经历了连续的洗涤+护理+干燥周期，即所谓的化妆品处理。该项目所使用的洗发水和护发素均经过精心挑选，适用于细质头发。每根发束在三个不同的时间点进行拍照：化妆品处理前；进行两次化妆品处理后，以及额外第三次化妆品处理后的时间点。在每个时间点，每根发束从三个不同的角度（-45度、0度和+45度）进行拍摄，从而为每根发束生成总共九张图像。对于数据库中的每张图像，我们还提供了相应的头发分割掩码，该掩码能够识别原始图像中的头发位置区域。
