Learning What and Where to Draw
This provides a more efficient interface for image synthesis with fine-grained control over content and layout, addressing a limitation in generative models for applications like design and visualization.
The paper tackles the problem of generating images with precise control over object location and pose, which existing GANs lack, and demonstrates high-quality 128 x 128 image synthesis on the Caltech-UCSD Birds dataset using text descriptions and object location instructions.
Generative Adversarial Networks (GANs) have recently demonstrated the capability to synthesize compelling real-world images, such as room interiors, album covers, manga, faces, birds, and flowers. While existing models can synthesize images based on global constraints such as a class label or caption, they do not provide control over pose or object location. We propose a new model, the Generative Adversarial What-Where Network (GAWWN), that synthesizes images given instructions describing what content to draw in which location. We show high-quality 128 x 128 image synthesis on the Caltech-UCSD Birds dataset, conditioned on both informal text descriptions and also object location. Our system exposes control over both the bounding box around the bird and its constituent parts. By modeling the conditional distributions over part locations, our system also enables conditioning on arbitrary subsets of parts (e.g. only the beak and tail), yielding an efficient interface for picking part locations. We also show preliminary results on the more challenging domain of text- and location-controllable synthesis of images of human actions on the MPII Human Pose dataset.
