#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… — read more

#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… — read more

#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… — read more

#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. And, once… — read more

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

Hi ! Let’s do some face detection using one of the most popular methods: Haar Casacades (See references). I won’t write about Cascades, 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 cascade definition file. And, once… — read more

#Event – Resources used on my session for the @netcoreconf

Hi ! Another huge and amazing events from my friends at the @netcoreconf, perfect excuse to talk about python, machine learning, computer vision and more. This one was also tricky, no slides, just code during 50 min so here are some related resources. Code The code used during the session is available here: https://github.com/elbruno/events/tree/main/2020%2010%2003%20Netcoreconf%20Virtual Session… — read more

#Coding4Fun – How to control your #drone with 20 lines of code! (21/N)

Hi ! In my post series I already wrote about how to detect faces. We can do this with a camera and OpenCV. However, a drone can also be moved on command, so let’s write some lines to detect a face, and calculate the orientation and distance of the detected face from the center camera… — read more

#Coding4Fun – How to control your #drone with 20 lines of code! (12/N)

Hi! Today code objective is very simple, based on a request I received from internet: The drone is flying very happy, but if the camera detects a face, the drone will flip out ! Let’s take a look at the program working: This one is very similar to the previous one. I also realized that… — read more

#VSCode – Let’s do some #FaceRecognition with 20 lines in #Python (5/N)

Hi! And after yesterday’s post I realize that the code is working, but there is room for performance improvement. So, I went back to my 1st sample, the one for face detection and I added some code to get some times for Frames per Second (FPS). In my initial code, the app was working processing… — read more

Hi! Quick post today. I’ll pickup yesterday demo, showing the facial features and adding Face Recognition on top of that. In other words, we’ll move from this To this With a couple of extra lines for face recognition There is some room for performance improvement, so I’ll focus on this in next posts. The complete… — read more

#VSCode – Let’s do some #FaceRecognition with 20 lines in #Python (3/N)

Hi! In my previous posts I explained how to detect faces and perform face recognition in python. Today I’ll explore another feature in the face_recognition package: Find Facial Features. The live camera output will be something like this: Note: Special thanks to my daughter who is always OK to help me with this. The main… — read more
