Vectorized and performance-portable Quicksort
Mark Blacher, Joachim Giesen, Peter Sanders +1
Recent works showed that implementations of Quicksort using vector CPU instructions can outperform the non-vectorized algorithms in widespread use. However, these implementations a…
Committee Draft of JPEG XL Image Coding System
Alexander Rhatushnyak, Jan Wassenberg, Jon Sneyers +15
JPEG XL is a practical approach focused on scalable web distribution and efficient compression of high-quality images. It provides various benefits compared to existing image forma…
Randen - fast backtracking-resistant random generator with AES+Feistel+Reverie
Jan Wassenberg, Robert Obryk, Jyrki Alakuijala +1
Algorithms that rely on a pseudorandom number generator often lose their performance guarantees when adversaries can predict the behavior of the generator. To protect non-cryptogra…
Noise generation for compression algorithms
Renata Khasanova, Jan Wassenberg, Jyrki Alakuijala
In various Computer Vision and Signal Processing applications, noise is typically perceived as a drawback of the image capturing system that ought to be removed. We, on the other h…
Guetzli: Perceptually Guided JPEG Encoder
Jyrki Alakuijala, Robert Obryk, Ostap Stoliarchuk +3
Guetzli is a new JPEG encoder that aims to produce visually indistinguishable images at a lower bit-rate than other common JPEG encoders. It optimizes both the JPEG global quantiza…
Users prefer Guetzli JPEG over same-sized libjpeg
Jyrki Alakuijala, Robert Obryk, Zoltan Szabadka +1
We report on pairwise comparisons by human raters of JPEG images from libjpeg and our new Guetzli encoder. Although both files are size-matched, 75% of ratings are in favor of Guet…
