Blind Image Inpainting with Sparse Directional Filter Dictionaries for Lightweight CNNs

no code implementations13 May 2022 Jenny Schmalfuss, Erik Scheurer, Heng Zhao, Nikolaos Karantzas, Andrés Bruhn, Demetrio Labate

Blind inpainting algorithms based on deep learning architectures have shown a remarkable performance in recent years, typically outperforming model-based methods both in terms of image quality and run time.

On the Design of Multi-Dimensional Compactly Supported Parseval Framelets with Directional Characteristics

1 code implementation22 Jun 2018 Nikolaos Atreas, Nikolaos Karantzas, Manos Papadakis, Theodoros Stavropoulos

In this paper, we propose a new method for the construction of multi-dimensional, wavelet-like families of affine frames, commonly referred to as framelets, with specific directional characteristics, small and compact support in space, directional vanishing moments (DVM), and axial symmetries or anti-symmetries.
