Generative Visual Manipulation on the Natural Image Manifold
Realistic image manipulation is challenging because it requires modifying the image appearance in a user-controlled way, while preserving the realism of the result. Unless the user has considerable artistic skill, it is easy to "fall off" the manifold of natural images while editing. In this paper, we propose to learn the natural image manifold directly from data using a generative adversarial neural network. We then define a class of image editing operations, and constrain their output to lie on that learned manifold at all times. The model automatically adjusts the output keeping all edits as realistic as possible. All our manipulations are expressed in terms of constrained optimization and are applied in near-real time. We evaluate our algorithm on the task of realistic photo manipulation of shape and color. The presented method can further be used for changing one image to look like the other, as well as generating novel imagery from scratch based on user's scribbles.

Interactive Image Generation
Our system can create new imagery based on user's scribbles. Letís draw an outdoor scene.
Here we demonstrate how to achieve the above result.
We can use our drawing interface to design products as well.
Intelligent Image Editing
Our interactive system allows a user to manipulate image in a natural and realistic way.
Generative Image Transformation
Our system can automatically transform the shape and color of one image to look like another image.
