Minutes

  • Intel team
  • Org: Done:
    • Anastasia: fixed issue #18878
    • Amir: worked on amendments to Voronoi diagram construction with respect to new topology (i.e. Delaunay triangulation) defined by the new predicates. PR #19126 is being reviewed.
    • Alexander: Implemented full RISC-V testing pipeline for OpenCV CN CI with QEMU emulator. Prepared test suppression list for major modules.
      • Work on multi-core & multi-theading solution for RISC-V is in progress.
      • Implemented pre-commit pipeline for PR testing on Ubuntu 18.04. Work on ARM analogue is in progress.
      • Resolved several networking and security issues and exposed CI server to the Internet. CI master is available at https://build.opencv.org.cn/
      • Analyzed failed tests on CI, filed relevant bugs to Github. All issues are tracked in spreadsheet.
  • In progress:
    • Anastasia: working on #19183
    • Amir: started with issue #4775
    • Igor: Working on opencv-python packages build speed up
    • Alexander: CI job for PR testing on ARM
      • Read-only access for subset of jobs on CI: pre-commit, nightly.
      • General infrastructure-related tasks for China CI: notifications, backup, etc
  • Vadim in Shenzhen

In case we skip the meeting next week: Merry Christmas and Happy New Year everyone! Hope 2021 will be a beautiful and uneventful year unlike 2020 😄

  • OpenCV 4.5.1 / 3.4.13 release.
    • target release date: Dec 20-25
    • wiki: changelog
  • GSOC blogposts
  • OpenCV fails tests on ARM64, module : GAPI. Issues ## 19117..19124.
  • ARM tests tolerance check adjustment (put under #if condition)
  • China CI integration

Minutes

  • Release expected on time. AI to all: add notes to changelog.
  • AI to all GSoC 2020 maintainers: ping students. Blog post about GSoC project is required. Lydia will contact to RISC-V case author and Depth Fusion
  • G-API tests fail on ARM64. Alexander Alekhin reproduced a significant part of tests. The issue is treated as a non-accurate test implementation, but not a library issue. Alexander Smorkalov disables G-API on ARM64.
  • Alexander Smorkalov works on OpenCV China CI and stabilizes base builds. A soon as they are stable, Alexander will work on

Minutes

  • Vadim:
    • got back to China successfully. On the quarantine currently.
    • working on OE34 (named parameters), since it may affect a lot of OpenCV 5.x API. Stub solution for Python, Java, JS is ready. Now working on a good solution for Python.
    • Prepared PR 19082 with RISC-V copyright info, but it causes some confusion. It's now being resolved and the updated patch will be prepared shortly.
  • Anna:
    • new person (Amir) joined the team. Working on fixing Delaunay triangulation in one corner case (#19126)
    • Alexander is working on a number of PRs. ARM64 issue has been filed.
    • He is also working on OpenCV China CI.
    • Nearest-neighbor resize alignment is another topic.
    • Python bindings is in progress.
    • RISC-V build preparation is in progress.
  • Gary:
    • AprilTag: did not have meeting past week. Sent a bunch of datasets to the student for proper testing.
    • Want to take a look at color calibration, contributed by H inc.
    • OpenCV.org is unrolling; OpenCV trademark etc.
    • Negotiating possibility to "hire" expert to implement state-of-art bundle adjustment for OpenCV; self-calibration is another possible topic.
    • OpenCV board meetings need to be resumed. The nearest one is planned at the end of 2020.
  • Alexander:
  • Shiqi:
