RainS/MEG-Multi-Exposure-Gradient-dataset

This is a Multi-Exposure Gradient dataset for low light enhancement and also for overexposure recovery, which contains about 1000 group of photos. The contents include variety of scenes such as indoor, outdoor, sunny, rainy, cloudy, nightime, city, rural, campus and so on.

There are 5 photos in each group with different exposure gradient, from low light to overexposure noted as 01 to 05. We provide two versions, one is continuous shooting data, whose contents of each group maybe a little bit different because of the moving scene, but they have more natural illumination and color. The other is post processing data, whose contents of each group are strictly same, and the exposure is adjuste by PS. You can choose one version according to your requirement, for example the continuous shooting data for unsupervised learning and the post processing data for supervised learning.
