What is DraGAN?

DraGAN, short for "Drag Your GAN," is an innovative tool designed for interactive point-based manipulation of images generated through Generative Adversarial Networks (GANs). Developed by a team of researchers from prominent institutions including the Max Planck Institute for Informatics, MIT, and Google AR/VR, DraGAN allows users to manipulate visual content with remarkable precision and flexibility. By enabling users to "drag" points on an image to specific target locations, DraGAN facilitates the modification of poses, shapes, expressions, and layouts of various objects, ranging from animals and vehicles to landscapes and human faces.

The tool leverages advanced techniques in motion supervision and point tracking to provide an intuitive user experience, making it a significant advancement in the field of image manipulation. With DraGAN, users can achieve high-quality, realistic outputs even in complex scenarios, such as generating occluded content or maintaining the integrity of object shapes during deformation.
