  • Publication number: 20260120176
    Abstract: Provided are systems and methods for systems and methods for video virtual try-on with machine-learned video diffusion models. In particular, given an input garment image and person video, example systems and methods of the present disclosure operate to generate a high-quality try-on video of the person wearing the given garment, while preserving the person's identity and motion.

  • Publication number: 20250371345
    Abstract: A method includes receiving training data comprising a plurality of pairs of images. Each pair comprises a noisy image and a denoised version of the noisy image. The method also includes training a multi-task diffusion model to perform a plurality of image-to-image translation tasks, wherein the training comprises iteratively generating a forward diffusion process by predicting, at each iteration in a sequence of iterations and based on a current noisy estimate of the denoised version of the noisy image, noise data for a next noisy estimate of the denoised version of the noisy image, updating, at each iteration, the current noisy estimate to the next noisy estimate by combining the current noisy estimate with the predicted noise data, and determining a reverse diffusion process by inverting the forward diffusion process to predict the denoised version of the noisy image. The method additionally includes providing the trained diffusion model.
