Exclusively Dark (ExDARK) dataset which to the best of our knowledge, is the largest collection of low-light images taken in very low-light environments to twilight (i.e 10 different conditions) to-date with image class and object level annotations.

Exclusively Dark (ExDark) Image Dataset

Oct. 31, 2018 - accepted for publication in the CVIU.

Released on May 29, 2018


In order to facilitate a new object detection and image enhancement research, we introduce the Exclusively Dark (ExDark) dataset (CVIU - accepted). The Exclusively Dark (ExDARK) dataset is a collection of 7,363 low-light images from very low-light environments to twilight (i.e 10 different conditions) with 12 object classes (similar to PASCAL VOC) annotated on both image class level and local object bounding boxes.
