Random-Access Neural Compression of Material Textures

no code implementations26 May 2023 Karthik Vaidyanathan, Marco Salvi, Bartlomiej Wronski, Tomas Akenine-Möller, Pontus Ebelin, Aaron Lefohn

The continuous advancement of photorealism in rendering is accompanied by a growth in texture data and, consequently, increasing storage and memory demands.

Stochastic Texture Filtering

no code implementations9 May 2023 Marcos Fajardo, Bartlomiej Wronski, Marco Salvi, Matt Pharr

2D texture maps and 3D voxel arrays are widely used to add rich detail to the surfaces and volumes of rendered scenes, and filtered texture lookups are integral to producing high-quality imagery.

Fast and High-Quality Image Denoising via Malleable Convolutions

no code implementations2 Jan 2022 Yifan Jiang, Bartlomiej Wronski, Ben Mildenhall, Jonathan T. Barron, Zhangyang Wang, Tianfan Xue

These spatially-varying kernels are produced by an efficient predictor network running on a downsampled input, making them much more efficient to compute than per-pixel kernels produced by a full-resolution image, and also enlarging the network's receptive field compared with static kernels.

Procedural Kernel Networks

no code implementations17 Dec 2021 Bartlomiej Wronski

In this work, we introduce Procedural Kernel Networks (PKNs), a family of machine learning models which generate parameters of image filter kernels or other traditional algorithms.

Image Stylization: From Predefined to Personalized

no code implementations22 Feb 2020 Ignacio Garcia-Dorado, Pascal Getreuer, Bartlomiej Wronski, Peyman Milanfar

We present a framework for interactive design of new image stylizations using a wide range of predefined filter blocks.

Handheld Multi-Frame Super-Resolution

3 code implementations8 May 2019 Bartlomiej Wronski, Ignacio Garcia-Dorado, Manfred Ernst, Damien Kelly, Michael Krainin, Chia-Kai Liang, Marc Levoy, Peyman Milanfar

In this paper, we supplant the use of traditional demosaicing in single-frame and burst photography pipelines with a multiframe super-resolution algorithm that creates a complete RGB image directly from a burst of CFA raw images.
