Efficient Data Optimisation for Harmonic Inpainting with Finite Elements
Vassillen Chizhov, Joachim Weickert
Harmonic inpainting with optimised data is very popular for inpainting-based image compression. We improve this approach in three important aspects. Firstly, we replace the standar…
JPEG Meets PDE-based Image Compression
Sarah Andris, Joachim Weickert, Tobias Alt +1
Inpainting-based image compression is emerging as a promising competitor to transform-based compression techniques. Its key idea is to reconstruct image information from only few k…
Sparse Inpainting with Smoothed Particle Hydrodynamics
Viktor Daropoulos, Matthias Augustin, Joachim Weickert
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…
Compressing Colour Images with Joint Inpainting and Prediction
Rahul Mohideen Kaja Mohideen, Pascal Peter, Tobias Alt +2
Inpainting-based codecs store sparse, quantised pixel data directly and decode by interpolating the discarded image parts. This interpolation can be used simultaneously for efficie…
A Systematic Evaluation of Coding Strategies for Sparse Binary Images
Rahul Mohideen Kaja Mohideen, Pascal Peter, Joachim Weickert
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…
PDE Evolutions for M-Smoothers in One, Two, and Three Dimensions
Martin Welk, Joachim Weickert
Local M-smoothers are interesting and important signal and image processing techniques with many connections to other methods. In our paper we derive a family of partial differenti…
