The Parallel Algorithm for the 2-D Discrete Wavelet Transform

no code implementations25 Aug 2017 David Barina, Pavel Najman, Petr Kleparnik, Michal Kula, Pavel Zemcik

Until now, the transform on general-purpose processors (CPUs) was mostly computed using a separable lifting scheme.

Accelerating Discrete Wavelet Transforms on GPUs

no code implementations18 May 2017 David Barina, Michal Kula, Michal Matysek, Pavel Zemcik

The two-dimensional discrete wavelet transform has a huge number of applications in image-processing techniques.

Compression Artifacts Removal Using Convolutional Neural Networks

1 code implementation2 May 2016 Pavel Svoboda, Michal Hradis, David Barina, Pavel Zemcik

This paper shows that it is possible to train large and deep convolutional neural networks (CNN) for JPEG compression artifacts reduction, and that such networks can provide significantly better reconstruction quality compared to previously used smaller networks as well as to any other state-of-the-art methods.

Parallel Wavelet Schemes for Images

no code implementations2 May 2016 David Barina, Michal Kula, Pavel Zemcik

In this paper, we introduce several new schemes for calculation of discrete wavelet transforms of images.

CNN for License Plate Motion Deblurring

no code implementations25 Feb 2016 Pavel Svoboda, Michal Hradis, Lukas Marsik, Pavel Zemcik

In this work we explore the previously proposed approach of direct blind deconvolution and denoising with convolutional neural networks in a situation where the blur kernels are partially constrained.

Real-Time Pose Estimation Piggybacked on Object Detection

no code implementations ICCV 2015 Roman Juranek, Adam Herout, Marketa Dubska, Pavel Zemcik

Besides that, we collected a new traffic surveillance dataset COD20k which fills certain gaps of the existing datasets and we make it public.
