Happy Friday, and thanks for reading our first new Community Friday update! We’re back to showcase interesting and fun projects from the global OpenCV Community as submitted by you! If you’ve got a project you want to see on Community Friday, send it our way by filling out the submission form. This week our featured project is ColorSpace, which uses OpenCV to power a formable web-based image analysis tool. We’ll also show you a great talk hosted by our friends at OpenCVismo Brasilia, and some pics from an OpenCV training session in China.

Thank You: Over 200k Followers on LinkedIn

Yesterday we talked about how thankful we are for the OpenCV community, and today we’re adding another reason: OpenCV’s official account on LinkedIn has surpassed the 200,000 follower milestone! It’s by far the most active social media account for OpenCV, so if you haven’t followed yet, now is a good time to do so.

OpenCV also has active profiles on Mastodon, Twitter, and YouTube. Give us a like and subscribe today. Every follow helps these accounts grow and be promoted in the algorithm, and the bigger our subscriber numbers are the easier it is to find sponsors for our big contests!

Speaking of sponsors, we also just passed the 400 total donors milestone on our big IndieGoGo campaign to keep OpenCV free! If just 27% of OpenCV’s followers donated at the $11 level we’d achieve the campaign’s $500,000 goal and secure open licensing for the next version of OpenCV, OpenCV 5. If you’ve already backed the campaign, thank you so much for your generosity and support. If you haven’t: We’ll be so happy to have you join in the support.

Featured Project: ColorSpace

Co-creator Richard Harris Podolsky describes ColorSpace like so, “ColorSpace was a Pandemic Passion Project by Dave Sprague and myself – the purpose was to build a really cool scientific image analysis app and include all of our favorite OpenCV routines in one location and frontend it with a 3D rendering interface – to allow compelling visualization.”

It’s a very versatile tool, indeed. An image analysis multi-tool, it features myriad ways to inspect, visualize, and enhance any input image all within your web browser. Great work, Richard and Dave!

A Live Stream from OpenCVismo Brasil

Natalia, from friends at OpenCVismo Brasil, sent this talk in along with the following: “Hello, everyone! This [past] weekend, we had a live conversation with Felipe Meganha, a Computer Vision Engineer and Teacher. During this conversation we talked about the importance of OpenCV in the Brazilian economy and how it help us engineers to unleash our potential.” You can find the video on YouTube:

OpenCV China Leads A Training Session

In China, OpenCV held a practical training camp in collaboration with Elephant Robotics and Orbbec 3D. In total 45 participants from all over China took part in the event which took place in Shenzhen. Elephant Robotics and Orbbec 3D generously sponsored 15 myCobot 280 6-Axis Collaborative Robotic Arms and 15 Gemini2 stereo structured light 3D cameras. Trainees learnt to work with the robot arm and 3D camera to grip things using OpenCV, both the algorithms and how to implement them. Based on the photos it looks like a good time was had by all. Thanks to OpenCV China for the pictures and summary!

That’s it for our first new Community Friday! We hope you enjoyed it, and we’ll see you next time. 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!
