This dataset allows you to try your hand at detecting fake images from real images. I trained a model on images that I collected from the Minecraft video game. From the provided link, you have access to my trained model, and can generate more fake data, if you like. However, if you would like additional real data, you will need to capture it from Minecraft yourself.

This Minecraft image is obviously fake:

Some images are not as easily guessed, such as this fake image:

You will also have to contend with multiple times of the day. Darker images will be more difficult for your model.
