Patent number: 12141945Abstract: Techniques are disclosed for training and applying a denoising model. The denoising model includes multiple specialized denoisers and a generalizer, each of which is a machine learning model. The specialized denoisers are trained to denoise images associated with specific ranges of noise parameters. The generalizer is trained to generate per-pixel denoising kernels for denoising images associated with arbitrary noise parameters using outputs of the specialized denoisers. Subsequent to training, a noisy image, such as a live-action image or a rendered image, can be denoised by inputting the noisy image into the specialized denoisers to obtain intermediate denoised images that are then input, along with the noisy image, into the generalizer to obtain per-pixel denoising kernels, which can be normalized and applied to denoise the noisy image.Type: GrantFiled: February 19, 2020Date of Patent: November 12, 2024Assignees: Disney Enterprises, INC., ETH Zürich (Eidgenössische Technische Hochschule Zürich)Inventors: Zhilin Cai, Tunc Ozan Aydin, Marco Manzi, Ahmet Cengiz Oztireli

Patent number: 12087024Abstract: According to one implementation, an image compression system includes a computing platform having a hardware processor and a system memory storing a software code. The hardware processor executes the software code to receive an input image, transform the input image to a latent space representation of the input image, and quantize the latent space representation of the input image to produce multiple quantized latents. The hardware processor further executes the software code to encode the quantized latents using a probability density function of the latent space representation of the input image, to generate a bitstream, and convert the bitstream into an output image corresponding to the input image. The probability density function of the latent space representation of the input image is obtained based on a normalizing flow mapping of one of the input image or the latent space representation of the input image.Type: GrantFiled: March 6, 2020Date of Patent: September 10, 2024Assignees: Disney Enterprises, Inc., ETH ZurichInventors: Abdelaziz Djelouah, Leonhard Markus Helminger, Scott Labrozzi, Yuanyi Xue, Erika Varis Doggett, Jared McPhillen, Christopher Richard Schroers
