Something relative to image processing

• Используем WebP сегодня
• FLIF – Free Lossless Image Format
  • FLIF — свободный формат сжатия изображений
• BPG Image format, nice visual comparison
• Lucid image data compression
• Свободный формат Lepton сжимает файлы JPEG на 22% без потерь
• PNG vs WebP image size comparison
• Image command line compression tools

JPEG optimization:

• Introducing the ‘mozjpeg’ Project
  • mozjpeg binaries
  • mozjpeg plugin initiative for XnView

    Building mozjpeg

    # apt-get install cmake nasm
    $ git clone https://github.com/mozilla/mozjpeg.git
    $ cd mozjpeg
    $ cmake .
    $ make all install

• Tools for JPEG optimization, jpegoptim vs jpegtran vs mozjpeg

PNG optimization:

• Нейронная сеть как предиктор для кодирования изображений формата PNG
• A guide to PNG optimization
  • optipng -o7 $file && advpng -z -4 $file

optipng	site	Lossy compression of PNG images
AdvanceCOMP	site	Takes advantage of 7-Zip and Zopfli DEFLATE encoders which are 5-10% more effective that zlib
PNG lossy averaging filter		Optimized lossy PNG is still a bit larger than lossy JPEG-XR/WebP/JPEG-2K, but unlike these formats it's supported by all browsers

Comparison:

• Performance of libjpeg-turbo

• PicMonkey – free online image editing service

• Image Composite Editor
• Hugin – Panorama photo stitcher
