I've been working lately on computer vision projects, involving Tensorflow for deep learning, OpenCV for computer vision and OpenGL for computer graphics. I'm especially interested in hybrid approaches, where I mix deep learning stuff, opencv stuff, and classic OpenGL pipeline. The main idea is to avoid framing problems as black box problems, throw a neural … Continue reading Augmented Reality with OpenCV and OpenGL: the tricky projection matrix →

Testing deep learning neural networks on public datasets is fun, but it's usually on unseen data that you can really see how the published techniques really perform. Recently, I was trying to detect human faces on Game of Thrones footage. I was surprised to see that the most widely used techniques didn't fare really well. … Continue reading State of the art (2019) face detection with RetinaFace and MXNet →
