Optical coherence tomography image dataset of genuine and faux leather

We have recorded Optical Coherence Tomography (OCT) images of both genuine and faux leather samples. The genuine leather samples comprised leather from small and large ruminants. The data is organized into three folders: FauxLeatherSamples, LargeRuminantSamples, and SmallRuminantSamples, each containing 5 distinct samples. Therefore, a total of 15 different samples (5 small ruminants, 5 large ruminants, and 5 artificial/faux leathers) were scanned at different points on their surfaces.

Under the FauxLeatherSamples folder, OCT images corresponding to the 5 separate artificial leather samples are stored. To ensure approximate consistency in the data from the samples, the OCT scans were fixed to 2 mm from each image and saved in the same PNG format. We are making this labeled OCT leather type dataset publicly available.

The dataset consists of raw OCT images stored in 15 separate folders, all in the same format. Each folder contains only OCT scans taken randomly over a single genuine or faux leather sample. The OCT scans corresponding to the genuine leather samples are found under the folders named LargeRuminantSamples and SmallRuminantSamples. Furthermore, under these folders, subfolders labeled 1 to 5 contain OCT scans of five different leathers, all of which are genuine.

The scans are raw OCT-B image files, captured using ThorImage software on the Thorlabs OCT imaging system. No additional image processing or filtering has been performed on the raw OCT images. Each OCT scan is a separate image with the date and time of the scan stamped within the file name. For instance, under the folder LargeRuminantSamples, within Folder 1, there are OCT scans of the genuine leather sample 1, originating from a large ruminant leather piece. The file named "OCT Image 060315_12242021.png" in this folder corresponds to the OCT scan of the first leather sample taken on December 24, 2021, at 06:03:15.

本数据集收录了真伪皮革样品的光学相干断层扫描（OCT）图像。真皮革样品包括小型和大型反刍动物的皮革。数据被组织成三个文件夹：FauxLeatherSamples、LargeRuminantSamples和SmallRuminantSamples，每个文件夹内含5个独特的样品。因此，总共15个不同的样品（5个小型反刍动物、5个大型反刍动物和5个人工/伪皮革）在不同的表面点进行了扫描。在FauxLeatherSamples文件夹下，存储了对应于5个单独人工皮革样品的OCT图像。为确保样本数据的近似一致性，OCT扫描被固定在每张图像的2毫米处，并以相同的PNG格式保存。我们正将此标记的OCT皮革类型数据集公开发布。该数据集由存储在15个单独文件夹中的原始OCT图像组成，格式统一。每个文件夹仅包含随机对单个真或伪皮革样品进行的OCT扫描。对应真皮革样品的OCT扫描位于命名为LargeRuminantSamples和SmallRuminantSamples的文件夹下。此外，在这些文件夹下，标记为1至5的子文件夹包含五种不同皮革的OCT扫描，均为真皮革。扫描为原始OCT-B图像文件，使用Thorlabs OCT成像系统上的ThorImage软件捕获。对原始OCT图像未进行任何额外的图像处理或过滤。每个OCT扫描都是一个独立的图像，文件名中带有扫描的日期和时间戳。例如，在LargeRuminantSamples文件夹下，Folder 1中包含来自大型反刍动物皮革块的真皮革样品1的OCT扫描。该文件夹中名为“OCT Image 060315_12242021.png”的文件对应于2021年12月24日06:03:15拍摄的第一个皮革样品的OCT扫描。
