DIAST Variability Illuminated Thermal and Visible Ear Image Dataset

This is a collection of paired thermal and visible ear images. Images in this dataset were acquired in different illumination conditions ranging between 2 and 10700 lux. There are total 2200 images of which 1100 are thermal images while the other 1100 are their corresponding visible images. Images consisted of left and right ear images of 55 subjects. Images were capture in 5 illumination conditiond for every subjects. This dataset was developed for illumination invariant ear recognition study. In addition it can also be useful for thermal and visible image fusion research. The images in this dataset can be used as is. It was intended ear recognition in visible or thermal spectrum. There is also possibility for image fusion application.

本数据集汇聚了一组配对的体热与可见光耳部图像。图像采集于2至10700勒克斯的多种光照条件下。数据集中包含2200张图像，其中1100张为体热图像，其余1100张为其对应的可见光图像。图像涵盖了55位受试者的左右耳部图像。每名受试者的图像均在5种光照条件下进行采集。该数据集旨在为光照不变性耳部识别研究提供支持。此外，它亦适用于热图像与可见光图像融合研究。数据集中的图像可直接使用。其原意在于可见光或热光谱范围内的耳部识别，并具有图像融合应用的潜力。
