[C#] VGG Face - Multiple face detection / recognition

Last time we tried VGG Face at previous post to display face recognition in one picture, this time we improve it, detect multiple face in one image and recognize them.

Here I will use Haar Cascades to do face detection, you can also download other feature-based cascade classifiers at here.

[C#] VGG Face CNN descriptor first try

It's time to try face detection since done lot of object detection. At this post, I will try VGG Face Descriptor, test the pre-trained model result, then see what we can do in next phase.

As usual, OpenCv Dnn is our model test good friend.

[C#] OpenCvSharp DNN test with SSD

Last time, we compared different language running in OpenCv DNN at this article OpenCV DNN Speed Test in Python / C# / C++, this time we can test the newest OpenCvSharp with DNN moudule supported.

Electron first try with Active Directory and MSSQL access

Electron is a framework base on Chromium and Node.js, it can create cross platform native applications with web technologies run on Mac, Windows, and Linux.

Recently I got a request to make a application to do some automatic stuff on Mac and Windows, after search on google, I think Electron was worth to try. But sadly the project got cut-out few day ago, so I only can share some experience what I got.

[Tensorflow] Object Detection API test in Python and TensorflowSharp

Object detection in machine learning is a popular topic, this time I will test Tensorflow Object Detection API in Python(official) and TensorflowSharp(wrapper) and check the result.

Let's start with Python, my code was modify from Object Detection Demo with some simplify, avoid path/protobuf issue, hope this simple example can help more people successful test it.
