Learning sparse masks for diffusion-based image inpainting

T Alt, P Peter, J Weickert - Iberian Conference on Pattern Recognition and …, 2022 - Springer
Diffusion-based inpainting is a powerful tool for the reconstruction of images from sparse
data. Its quality strongly depends on the choice of known data. Optimising their spatial …

Deep spatial and tonal data optimisation for homogeneous diffusion inpainting

P Peter, K Schrader, T Alt, J Weickert - Pattern Analysis and Applications, 2023 - Springer
Diffusion-based inpainting can reconstruct missing image areas with high quality from
sparse data, provided that their location and their values are well optimised. This is …

Sparse inpainting with smoothed particle hydrodynamics

V Daropoulos, M Augustin, J Weickert - SIAM Journal on Imaging Sciences, 2021 - SIAM
Digital image inpainting refers to techniques used to reconstruct a damaged or incomplete
image by exploiting available image information. The main goal of this work is to perform the …

Exploiting the sensitivity of l2 adversarial examples to erase-and-restore

F Zuo, Q Zeng - Proceedings of the 2021 ACM Asia conference on …, 2021 - dl.acm.org
By adding carefully crafted perturbations to input images, adversarial examples (AEs) can
be generated to mislead neural-network-based image classifiers. L2 adversarial …

Gaining Insights into Denoising by Inpainting

D Gaa, V Chizhov, P Peter, J Weickert… - arXiv preprint arXiv …, 2023 - arxiv.org
The filling-in effect of diffusion processes is a powerful tool for various image analysis tasks
such as inpainting-based compression and dense optic flow computation. For noisy data, an …

Optimising data for exemplar-based inpainting

L Karos, P Bheed, P Peter, J Weickert - Advanced Concepts for Intelligent …, 2018 - Springer
Optimisation of inpainting data plays an important role in inpainting-based codecs. For
diffusion-based inpainting, it is well-known that a careful data selection has a substantial …

Optimal interpolation data for PDE-based compression of images with noise

Z Belhachmi, T Jacumin - … in Nonlinear Science and Numerical Simulation, 2022 - Elsevier
We introduce and discuss shape-based models for finding the best interpolation data in the
compression of images with noise. The aim is to reconstruct missing regions by means of …

Image Compression with Isotropic and Anisotropic Shepard Inpainting

RMK Mohideen, T Alt, P Peter, J Weickert - arXiv preprint arXiv …, 2024 - arxiv.org
Inpainting-based codecs store sparse selected pixel data and decode by reconstructing the
discarded image parts by inpainting. Successful codecs (coders and decoders) traditionally …

Restoration by compression

Y Dar, M Elad, AM Bruckstein - IEEE Transactions on Signal …, 2018 - ieeexplore.ieee.org
In this paper, we study the topic of signal restoration using complexity regularization,
quantifying the compression bit-cost of the signal estimate. While complexity-regularized …

A systematic evaluation of coding strategies for sparse binary images

RMK Mohideen, P Peter, J Weickert - Signal Processing: Image …, 2021 - Elsevier
Inpainting-based compression represents images in terms of a sparse subset of its pixel
data. Storing the carefully optimised positions of known data creates a lossless compression …
