Introduction

We study the problem of generating a set of realistic and diverse backgrounds when given only a small foreground region, which we formulate as image outpainting task. We propose a generative model by improving the normalized diversification framework to encourage diverse sampling in this conditional synthesis task. The results show that our proposed approach can produce more diverse images with similar or better quality compare to the state-of-the-arts methods.

Usage

The synthetic experiment and real image experiment codes are in the folder "synthetic_data" and "real_image" respectively.
