#OpenCV – Access a local camera 🀳in F# πŸ“

Hi ! NET is in anniversary mode, and in Dev.to blog, someone asked about these samples in F#. It’s been a while since I wrote some F# code, and this is the perfect excuse to start. Today Post: Access a local camera and show the camera frames in an OpenCV window. In following posts we…… Continue reading #OpenCV – Access a local camera 🀳in F# πŸ“

#OpenCV – Detect and blur faces 😁 using DNN in C#

Hi ! NET is in anniversary mode, so I think it will be a good idea to share some camera samples in C#. For these demos I’m using C# 6 and OpenCVSharp as OpenCV wrapper for .NET. Today post: detect a face using a DNN model and blur the face area. This demo also show…… Continue reading #OpenCV – Detect and blur faces 😁 using DNN in C#
