Comparison of Lossless Image Formats
David Barina
In recent years, a bag with image and video compression formats has been torn. However, most of them are focused on lossy compression and only marginally support the lossless mode.…
Evaluation of 4D Light Field Compression Methods
David Barina, Tomas Chlubna, Marek Solony +2
Light field data records the amount of light at multiple points in space, captured e.g. by an array of cameras or by a light-field camera that uses microlenses. Since the storage a…
The Parallel Algorithm for the 2-D Discrete Wavelet Transform
David Barina, Pavel Najman, Petr Kleparnik +2
The discrete wavelet transform can be found at the heart of many image-processing algorithms. Until now, the transform on general-purpose processors (CPUs) was mostly computed usin…
Simple Signal Extension Method for Discrete Wavelet Transform
David Barina, Pavel Zemcik, Michal Kula
Discrete wavelet transform of finite-length signals must necessarily handle the signal boundaries. The state-of-the-art approaches treat such boundaries in a complicated and inflex…
Accelerating Discrete Wavelet Transforms on Parallel Architectures
David Barina, Michal Kula, Michal Matysek +1
The 2-D discrete wavelet transform (DWT) can be found in the heart of many image-processing algorithms. Until recently, several studies have compared the performance of such transf…
Accelerating Discrete Wavelet Transforms on GPUs
David Barina, Michal Kula, Michal Matysek +1
The two-dimensional discrete wavelet transform has a huge number of applications in image-processing techniques. Until now, several papers compared the performance of such transfor…
