EZ-Face is the first in what I plan to develop into a suite of supporting application for EZ-Builder and other robotics applications. EZ-Face performs multiple face recognition. It has a interface for training faces and assigning names. When the application sees faces that are recognized the names are displayed and visually you'll see boxes around the faces with the names assigned. If a face is detected but not recognized there will be a display of a box around the face with no name. The more pictures of a face you train, the easier it is for the application to recognize a face.
This is a stand alone application developed in C# under Visual Studio.NET
2013. You should have .NET framework 4.5 and it is for Windows7 and Windows8.x systems.
This project showcase explains the technology behind the application and highlights development milestones.Technology:
Developed in .NET Visual Studio 2013 (you can use express versions with the source code)
Designed to work with EZ-Builder but could be integrated into other software or robotic systems
Is a standalone application
Is open source, source code is included
Uses emgu cv wrapper for .NET (Open CV)Resources:

DJ Sures, for making EZ-Robot and EZ-Builder so robust
Rich, for his help with EZ-Builder scripting
Sergio, for his emgu cv examplesBasic Usage Direction (after download and install):
1.) Open EZ-Builder and load the included EZ-Face example
2.) Click on the Script start button (this sets up the communications from the EZ-Builder side of things)
3.) Open the EZ-Face application
4.) Refresh your camera list (click the button)
5.) Select your camera (in the drop down list)
6.) Click the "1. Detect and recognize" button
7.) Train at least one face
8.) Change the local address and port number as needed (the local IP address may not be your computer's address - you can enter "localhost" and leave the port set to 6666 unless you changed that setting in EZ-Builder)
9.) Click File and select Save User Settings (to store your changes)
10.) Click Connection (this opens the communication line to EZ-Builder from the EZ-Face app side
11.) Allow EZ-Face to recognize the face you trained - then with your computer speakers turned on EZ-Builder should speak "Hello (the name of the face you trained)"
12.) If the example work - integrate in your EZ-Robot applications as you see fitTips:
1.) If after training several faces if you get false recognition of faces (faces recognized with the wrong name) - to correct this you should train the incorrectly recognized faces with the correct name. After a couple of training pictures are stored the accuracy of the face recognition will improve.
2.) Do not train faces with one camera, then switch to another camera for face recognition - recognition accuracy will drop.Using Two Cameras:
What I found worked best was to start EZ-Builder, select the camera I wanted and started the camera feed, then I started EZ-Face.
If I reverses the process (even though I was selecting a different camera) I would get a black image in EZ-Builder.2.26.14 Update:
I still have several improvements I want to make before I upload the first public version of the application. 3.2.14 Update:
The first public version is ready for release and is posted at the link below. This version has many user improvements to allow you store many settings, including http and port address, camera device, logging of faces in a text file (up to 1mb of data before the file auto deletes), face variable output to EZ-Builder, face training and more.3.3.14 Update:
I updated the script, version 3.3.14 has the HTTP server panel (which is not used - you don't need to start it) but it does show you your computer's IP address so you can enter it in EZ-Face. Remember to save your settings under the File Menu. I also changed the script so it will no only speak for variable values greater than "" or NULL. EZ-Face3.3.14.EZB3.7.14 Update:
I updated the EZ-Face application: "localhost" is now the default address, new option for auto connect, functions to receive commands from EZ-Builder or other 3rd party application to stop and start the camera feed within EZ-Face. There is also a new EZ-Builder project with several new scripts to test out the functions. Please go to my site to download the latest version. You will also find a video there that demonstrations the new functions and provides directions for setup and usages. Download:
The latest version will be published here: http://www.j2rscientific.com/software
