Spoiler: They’re much better now! OpenCV RANSAC is dead. Long live the OpenCV USAC! Last year a group of researchers including myself from UBC, Google, CTU in Prague and EPFL published a paper “Image Matching across Wide Baselines: From Paper to Practice“, which, among other messages, has shown that OpenCV RANSAC for fundamental matrix estimation […]
Utilising Second-Order Information for Deep Image Retrieval
Tony Ng is a Ph.D. student at MatchLab, Imperial College London. He is supervised by Dr. Krystian Mikolajczyk and co-supervised by Dr. Vassileios Balntas. His research interests focus on improving visual localisation using both deep learning and classical multiview geometry. Image retrieval is a long-standing computer vision problem. It is used in image indexing, e.g. […]
OpenCV-Python Is Now An Official OpenCV Project
Good news, everyone! OpenCV.org is pleased to announce that the popular and long-running package OpenCV-Python is now an official OpenCV project. What is OpenCV-Python? It’s a package that contains pre-built OpenCV with dependencies and Python bindings, so there’s no need to install OpenCV separately. Thanks so much to package maintainer Olli-Pekka Heinisuo (@skvark), who developed […]
OpenVINO: Merging Pre and Post-processing into the model
We have already discussed several ways to convert your DL model into OpenVINO in previous blogs (PyTorch and TensorFlow). Let’s try something more advanced now.
Interview with Daniel Cremers in the new episode of OpenCV AI for Entrepreneurs podcast
In this week’s episode of the AI for Entrepreneurs, Anna Petrovicheva, CTO of OpenCV.AI, is talking to Daniel Cremers, Professor of Informatics and Mathematics and Chair of Computer Vision & Artificial Intelligence at the Technische Universität Münche and one of the most influential scientists in Germany. It is a fascinating conversation about Daniel’s career path […]
Google Summer of Code results in one video!
This year it was the 10th time when OpenCV participated in Google Summer of Code program (GSoC 2020), and it went really well! GSoC is an international program organized and sponsored by Google. It’s aimed at supporting students development and advancing various open-source projects. In 2020 OpenCV got funding for 14 projects. For three months, […]

Kornia team is releasing a new version that includes different functionalities to work with 3D augmentations and volumetric data, local features matching, homographies and epipolar geometry
Understanding Transductive Few-shot Learning
How has transduction elevated few-shot algorithms to a new state-of-the-art?
Hybrid CV/DL pipelines with OpenCV 4.4 G-API
Modern Computer Vision (CV) and Video Analytics (VA) problems are solved with a combination of traditional methods and Deep Learning (DL). Deep Neural Network Inference becomes a crucial tool in the domain, but integrating it into the application and the further deployment is sometimes non-trivial — especially if the algorithm is built with multiple DL […]
Training A Personal Protective Equipment (PPE) Detector From Scratch with OAK
Note: This article was originally posted on the OpenCV AI Kit Kickstarter campaign. OAK was started to solve a human safety issue- and that goal is still baked into the project. We also believe that in order to be maximally effective, this technology needs to be simple to use. One of the biggest ways these […]
