Happy Friday, OpenCV community! Community Friday is our showcase of interesting and fun projects as submitted by you! If you’ve seen or made a project which uses OpenCV you want to see on Community Friday, send it to us by filling out the submission form. Today we’ll be showing a new tutorial on how to use Rerun with OpenCV, a look back at OpenCV’s 20th anniversary, our webinar about ROSCon 2023, and how you can help keep OpenCV free by supporting our IndieGoGo campaign.
Use OpenCV With Rerun, An Advanced Data Visualizer
Our friends at Rerun have released version 0.11 of their exciting data visualization tool. Among the changes are a new “Visible Time Range” feature, and a npm package of their excellent web viewer. You may remember Rerun were our guests on OpenCV Live episode 94, which you can watch on our YouTube channel.
Most importantly for us, along with the new release they’ve published a minimal C++ example of using Rerun together with OpenCV (C++ version) and Eigen. See their GitHub for a full example
Dr. Andrew Ng on OpenCV
As part of OpenCV’s 20th anniversary, OpenCV community member and AI legend Dr. Andrew Ng took a few moments to talk about the importance of open source in science and technology:
“In the software world, we all stand on the shoulders of giants and it’s by sharing our work and building on each other’s work that together as a community we can build these amazing software products. I think OpenCV has been one very important building block built by giants that I think all of us should feel privileged to be able to stand on their shoulders.”
Dr. Andrew Ng
You can watch our full interview with Dr. Ng on the official OpenCV YouTube channel.
Pledge To Support OpenCV
Here’s the short version of awesome stuff coming to OpenCV in version 5: A new Deep Neural Network (DNN) module, Accelerated image processing, Truetype font support with full Unicode support, Improved support for fisheye camera calibration and multi-camera support, better support for depth cameras, new packages, better optimization for AMD CPUs and GPUs, much needed code refactoring and new tutorials for the new version.
We have just 16 days left in our campaign to keep OpenCV free for everyone and we have raised just $48,796 toward our $500,000 goal. We know $500k is not a small thing to ask- but we’re asking because it is what we need to not just pay the core developers who will produce OpenCV 5 but to ensure that we can do it the Open Source free-access way as we always have. The best thing you can do is contribute personally: Visit our campaign page, enter your email, and contribute to the campaign. Every contribution, no matter how big or small, makes a difference.
How Else You Can Help OpenCV
Here’s how else you can help the campaign, if you can’t afford to contribute financially or already have:
- Follow OpenCV and share our posts about the campaign on LinkedIn, Twitter, and Mastodon.
- Sign Up To Volunteer: Fill out the volunteer application form, and let us know how you can help with the campaign. Thank you to the 100+ who have already signed up to volunteer! The more the merrier!
- Talk About OpenCV: Talk with your boss, your manager, and co-workers about supporting OpenCV if your workplace benefits from our free library. Be clear that this is a very important time to show financial support.
- Make a personal post on your social media accounts about why you feel it’s important to support OpenCV. Include a link to the campaign page at http://igg.me/at/opencv5. Don’t forget the hashtags #FreeOpenCV, #ILoveOpenCV, or even just #OpenCV.
We can’t stress enough how important this campaign is to the future of OpenCV but to all open source computer vision and artificial intelligence. The world is watching, and we want to show that there is a future in keeping the most consequential technological advances available free to all. Even though we are behind our goal, we still believe. Every share, every conversation, every personal note means a lot. We hope you’ll help.
See What The ROS Community Is Up To on OpenCV Live
Kat Scott, Developer Advocate at ROS, joined Phil Nelson on OpenCV Live for a fun show and tell about everything that went on at ROSCon 2023 in New Orleans. Kat also shared some personal stories and let us know that next year ROSCon will be in Denmark!

That’s all for this week’s edition of Community Friday. If you missed last week, read the post in our blog archives. Don’t forget: If you’ve got a project you want to see on Community Friday, send it our way by filling out the submission form. No project is too big or too small, if it uses OpenCV we want to hear about it!
