Users prefer Guetzli JPEG over same-sized libjpeg

2017-03-13 · Jyrki Alakuijala, Robert Obryk, Zoltan Szabadka, Jan Wassenberg

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 Guetzli. This implies the Butteraugli psychovisual image similarity metric which guides Guetzli is reasonably close to human perception at high quality levels. We provide access to the raw ratings and source images for further analysis and study.

Guetzli: Perceptually Guided JPEG Encoder

2017-03-13 · Jyrki Alakuijala, Robert Obryk, Ostap Stoliarchuk, Zoltan Szabadka 외

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 quantization tables and the DCT coefficient valu…

Users prefer Jpegli over same-sized libjpeg-turbo or MozJPEG

2024-03-27 · Martin Bruse, Luca Versari, Zoltan Szabadka, Jyrki Alakuijala

We performed pairwise comparisons by human raters of JPEG images from MozJPEG, libjpeg-turbo and our new Jpegli encoder. When compressing images at a quality similar to libjpeg-turbo quality 95, the Jpegli images were 54…

Deep Selector-JPEG: Adaptive JPEG Image Compression for Computer Vision in Image classification with Human Vision Criteria

2023-02-19 · Hossam Amer, Sepideh Shaterian, En-hui Yang

With limited storage/bandwidth resources, input images to Computer Vision (CV) applications that use Deep Neural Networks (DNNs) are often encoded with JPEG that is tailored to Human Vision (HV). This paper presents Deep…

Bitstream-Based JPEG Image Encryption with File-Size Preserving

2018-08-17 · Hiroyuki Kobayashi, Hitoshi Kiya

An encryption scheme of JPEG images in the bitstream domain is proposed. The proposed scheme preserves the JPEG format even after encrypting the images, and the file size of encrypted images is the exact same as that of …

Learned JPEG Compression for DNN Vision

2026-06-15 · Kaixiang Zheng, Ahmed H. Salamah, Siyu Chen, En-Hui Yang arxiv

JPEG, a lossy image compression technique designed for human viewers, has maintained its dominance for decades. However, in the era of artificial intelligence (AI), a substantial portion of image data, often compressed b…
