#Net5 – C#9 logical operators “is” and “is not” are super cool 🆒🆒🆒

Hi ! In the line of good features, that are also nice to read, the new use of is and is not is a huge improvement in readability. As usual, old school validation for objects and types: // old school if(!(testObj is MyClass)) {...} And now, we can type the validation with some style: // … Continue reading #Net5 – C#9 logical operators “is” and “is not” are super cool 🆒🆒🆒

#Net5 – C#9 target-typed new expressions are super cool 🆒🆒🆒

Hi ! I know I'm late to the party here, however I'm still enjoying some of the new C# 9 features a lot. I just realized that now, I can create objects in a different way, which is still super clear to read. Disclaimer: some of the new features are cool, however my gut told … Continue reading #Net5 – C#9 target-typed new expressions are super cool 🆒🆒🆒

#Net5 – C#9 “records”, “with” and “this”, a super cool mix 🆒🆒🆒

Hi ! Our next podcast episode is focused on .Net 5. We had an amazing chat around a lot of features, and of course, C# 9 was part of the conversation. I got this amazing post [C# 9.0: Records – Work With Immutable Data Classes] from Tomas Huber, in my reading notes and working with … Continue reading #Net5 – C#9 “records”, “with” and “this”, a super cool mix 🆒🆒🆒

#OpenCV – Open a video file 🎥 and save each frame as a PNG 🖼 file to a folder 📂#Net5

Hi ! A couple of days ago I wrote this post, and made the sample with Python. So today, same scenario, however with C# 9 and Net5. This is a non-usual scenario, however I'm on a point where I need to extract all the frames from a video file. The reason: some of these frames … Continue reading #OpenCV – Open a video file 🎥 and save each frame as a PNG 🖼 file to a folder 📂#Net5

#OpenCV – Open a video file 🎥 and save each frame as a PNG 🖼 file to a folder 📂#Python

Hi ! This is a non-usual scenario, however I'm on a point where I need to extract all the frames from a video file. The reason: some of these frames will be used to train a Machine Learning model. There are tools that can do this, however it's a nice moment to do some OpenCV … Continue reading #OpenCV – Open a video file 🎥 and save each frame as a PNG 🖼 file to a folder 📂#Python

#dotnet – Display a video file🎥 in Winform using #OpenCV and #net5

Hi ! Super short post today, however is the base of the next series of posts around OpenCV and .Net 5. I already wrote on how to work with a webcam, and now it's time to share a simple piece of code to show How to open and process a video frame by frame I've … Continue reading #dotnet – Display a video file🎥 in Winform using #OpenCV and #net5

#dotnet – Packaging my WinForm #OpenCV and #net5 app in a one-self contained file (Thanks @shanselman!)

Hi ! A couple of days ago, Scott Hanselman posted about a super cool feature (see references): ... you can make a single EXE that will run on any Windows Machine in two commandsHow to make a WinForms app with .NET 5 entirely from the command line and publish as one self-contained file and I … Continue reading #dotnet – Packaging my WinForm #OpenCV and #net5 app in a one-self contained file (Thanks @shanselman!)

#dotnet – Pose detection from the 🎦 camera feed using #OpenCV and #net5. Home-made #kinect!

Hi ! LearnOpenCV is an amazing resource to learn about OpenCV. And, it has lot of scenarios of real life problem solved with OpenCV. Most of the samples are in C++ or Python, so I decided to pick one related to pose estimation, and using .Net 5 in a Winforms App, build something like this: … Continue reading #dotnet – Pose detection from the 🎦 camera feed using #OpenCV and #net5.

#dotnet – GoogleNet detection from the 🎦 camera feed using #OpenCV and #net5. Bonus: C++ to C# time!

Hi ! So I was browsing in the OpenCV documentation and I find a nice sample that uses opencv_dnn module for image classification by using GoogLeNet trained network from Caffe model zoo. So I give it a try, and get a decent .Net 5 Winforms App running at ~30 FPS. The model was trained with … Continue reading #dotnet – GoogleNet detection from the 🎦 camera feed using #OpenCV and #net5. Bonus: C++ to C# time!

#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
