Hotels-50K Global Hotel Recognition Dataset

The Hotels-50K dataset contains over 1 million images from 50,000 different hotels around the world. The images come from travel websites as well as the TraffickCam mobile app, which allows everyday travelers to submit pictures of their hotel rooms to help fight human trafficking. TraffickCam images are visually more similar to images from human trafficking investigations than images from travel websites.

The training set includes 1,027,871 images from 5,000 different hotels and 92 major hotel chains. The test set contains 17,954 images from 5,000 different hotels.
