A Sub-band Approach to Deep Denoising Wavelet Networks and a Frequency-adaptive Loss for Perceptual Quality

Caglar Aytekin, Sakari Alenius, Dmytro Paliy +1

In this paper, we propose two contributions to neural network based denoising. First, we propose applying separate convolutional layers to each sub-band of discrete wavelet transfo…

A Compression Objective and a Cycle Loss for Neural Image Compression

Caglar Aytekin, Francesco Cricri, Antti Hallapuro +3

In this manuscript we propose two objective terms for neural image compression: a compression objective and a cycle loss. These terms are applied on the encoder output of an autoen…

A Theoretical Investigation of Graph Degree as an Unsupervised Normality Measure

Caglar Aytekin, Francesco Cricri, Lixin Fan +1

For a graph representation of a dataset, a straightforward normality measure for a sample can be its graph degree. Considering a weighted graph, degree of a sample is the sum of th…
