#OpenCV – Access a local camera 🤳in F# 📝

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# 📝

#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#

#dotnet – Age and Gender estimation from the 🎦 camera feed using #OpenCV and #net5

Hi ! Face detected, so next step is to use some prebuild models to perform additional actions: like estimate the Age of a face, and also the Gender. In order to do this, I downloaded a couple of models from here. Disclaimer: these models are just sample models, do not use them in production. These…… Continue reading #dotnet – Age and Gender estimation from the 🎦 camera feed using #OpenCV and #net5

#dotnet – Detecting Faces, DNN vs Haar Cascades from the 🎦 camera feed using #OpenCV and #net5

Hi ! In one session around computer vision, someone ask the question about which approach is better Haar Cascades or DNN? And the answer can be show using the video below As you can see Haar Cascades works great for faces looking directly to the camera, with good lights and in optimal conditions. However, once…… Continue reading #dotnet – Detecting Faces, DNN vs Haar Cascades from the 🎦 camera feed using #OpenCV and #net5

#dotnet – Detecting Faces using DNN from the 🎦 camera feed in a WinForm using #OpenCV and #net5

Hi ! Let’s do some face detection using a DNN model (See references). As yesterday, I won’t write about details, there are almost 20 years of online documentation available. And, IMHO opinion code is much more useful that long writing, so let’s go there. 1st load the Caffe model and the config file. // download…… Continue reading #dotnet – Detecting Faces using DNN from the 🎦 camera feed in a WinForm using #OpenCV and #net5
