Exploiting the Signal-Leak Bias in Diffusion Models

no code implementations27 Sep 2023 Martin Nicolas Everaert, Athanasios Fitsios, Marco Bocchio, Sami Arpa, Sabine Süsstrunk, Radhakrishna Achanta

This enables us to generate images with more varied brightness, and images that better match a desired style or color.

Diffusion in Style

no code implementations ICCV 2023 Martin Nicolas Everaert, Marco Bocchio, Sami Arpa, Sabine Süsstrunk, Radhakrishna Achanta

Not adapting this initial latent tensor to the style makes fine-tuning slow, expensive, and impractical, especially when only a few target style images are available.

What You See is What You Classify: Black Box Attributions

1 code implementation23 May 2022 Steven Stalder, Nathanaël Perraudin, Radhakrishna Achanta, Fernando Perez-Cruz, Michele Volpi

These attributions are provided in the form of masks that only show the classifier-relevant parts of an image, masking out the rest.

Uncertainty Surrogates for Deep Learning

no code implementations16 Apr 2021 Radhakrishna Achanta, Natasa Tagasovska

We show how our approach can be used for estimating uncertainty in prediction and out-of-distribution detection.

Self-Binarizing Networks

no code implementations2 Feb 2019 Fayez Lahoud, Radhakrishna Achanta, Pablo Márquez-Neila, Sabine Süsstrunk

To obtain similar binary networks, existing methods rely on the sign activation function.

Fourier-Domain Optimization for Image Processing

1 code implementation11 Sep 2018 Majed El Helou, Frederike Dümbgen, Radhakrishna Achanta, Sabine Süsstrunk

Image optimization problems encompass many applications such as spectral fusion, deblurring, deconvolution, dehazing, matting, reflection removal and image interpolation, among others.

Deep Residual Network for Joint Demosaicing and Super-Resolution

1 code implementation19 Feb 2018 Ruofan Zhou, Radhakrishna Achanta, Sabine Süsstrunk

By training on high-quality samples, our deep residual demosaicing and super-resolution network is able to recover high-quality super-resolved images from low-resolution Bayer mosaics in a single step without producing the artifacts common to such processing when the two operations are done separately.

Uniform Information Segmentation

no code implementations27 Nov 2016 Radhakrishna Achanta, Pablo Márquez-Neila, Pascal Fua, Sabine Süsstrunk

Since information is a natural way of measuring image complexity, our proposed algorithm leads to image segments that are smaller and denser in areas of high complexity and larger in homogeneous regions, thus simplifying the image while preserving its details.
