  • libjpeg-turbo

    Main libjpeg-turbo repository

    • This is interesting from the standpoint of how new JVM features can be used to improve performance (what I presume the article's main purpose to have been), but the image processing improvement itself isn't head-turning. Also, we've found that libjpeg-turbo (https://libjpeg-turbo.org/) is ~5x (IIRC, can re-run my JMH benchmark if anyone wants me to) as fast for decoding JPEGs as ImageIO, so we wouldn't even benefit from this change in 21 much.

  • JDK

    JDK main-line development https://openjdk.org/projects/jdk

    • They also recently removed many unneeded array initialisation to zero loops in the image API: https://github.com/openjdk/jdk/pull/12147/files

  • InfluxDB

  • BoofCV

    Fast computer vision library for SFM, calibration, fiducials, tracking, image processing, and more.

    • Is there any fast way to get pixel values and pixel coordinate? I had to jump through a lot of hoops to get convert BufferedImages into a format that's useful for image processing it to be a reasonable speed in BoofCV. getRGB() is glacial. At one point I was trying to convince the JDK team to make private data structures public again. Right now it's inconsistent what you have access too.
