OpenCV Hackathon is done and we want to say “Thank You!” to the OpenCV community and engineers who helped the OpenCV team to make the library better. The hackathon brings a lot of changes and improvements, but it’s important to highlight some of them:

• Stefan Bruens (@StefanBruens) contributed OpenJPEG library integration code as an alternative solution to Jasper library. The code has not been merged to upstream branch yet, but we will definitely do it right after the coming release.
• Vadim Pisarevsky (@vpisarev) contributed a patch that improved HoughCircles algorithm quality and proposed several fixes for Mac.
• Ganesh Kathiresan (@ganesh-k13) implemented more accurate processors enumeration that fixes threads overspawn in containerized invironments like Docker containers and Kubernetes pods.
