In this work, we aim to automate the photo blending process through deep reinforcement learning. We focus on a specific and popular photo blending style - Double Exposure. The image below shows some example results of our method:

The figure below shows the overview of our system. The inputs of our method are two photos: foreground and background. We first train a quality network to evaluate the aesthetics quality of blending photos with human preference annotation on random blending photos. Then a deep reinforcement learning based agent is trained to optimize the parameter for the background alignment and photometric adjustment. Using the predicted parameters, the blending engine renders the final blending photo.
