Ez-face

StorySkip to comments

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: (Things I found helpful in creating the application)
EZ-Builder Telnet interface tutorial (Enable Telnet as the first part Shows, this is used to test communications manually to EZ-Builder via TCP/IP): http://www.ez-robot.com/Tutorials/Help.aspx?id=159
If you do not have Telnet installed on your system go to this site: http://technet.microsoft.com/en-us/library/cc771275

Acknowledgements:
DJ Sures, for making EZ-Robot and EZ-Builder so robust
Rich, for his help with EZ-Builder scripting
Sergio, for his emgu cv examples

Basic 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 fit

Tips:
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.EZB

3.7.14 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

Dear Sir,

I am suing your EZ-Face software and developing an multiple face recognition attendance software.
But I am facing some problem, I am using Logitech HD Webcam - C615 when we start recognition its not detecting with accuracy.

Example: if I show “alex face” its detecting with some other name. like “john”. you can see the attachment face detecting on different name (Please suggest me the solution.)

And second one is how can I connect my IP camera with this software?
Example My IP camera link is http://192.168.226.201/Pages/login.htm and login id is admin and password is 123456
I need your support Please help me … I am waiting for your reply..

I am no longer supporting this software at this time. For any enhancements you'll need to develop those on your own if you wish to. I would recommend using RoboRealm for vision processing as it will allow you learn faces. There are also several vision plug ins DJ Sures has added to EZ-Builder that allow you do additional vision processing Combining those are going to be better than what EZ-Face was developed to be back in 2014.

Good luck with your project.

EZ-Builder has OBJECT TRACKING AND TRAINING built-in. There is no reason to use roborealm or ez-face. Read the manual: http://www.ez-robot.com/Tutorials/Help.aspx?id=80

Just looking into facial recognition. I see the Ezbuilder has facial tracking, but does it have a means to differentiate between multiple faces - like see one - say hi XXXX see another say hi YYY, like that? If I missed it, a link to howto, is appreciated.

1) The post that you responded to answers the question. For more information, continue reading in my response.

2) Visit The Robot Program by clicking on LEARN on the top menu to see activities on using your ez-robot. In this question, the answer to training a specific face can followed in episode #46. The link is here: http://www.ez-robot.com/Tutorials/Lesson/106

3) Click the ? (question mark) next X (close) no any control in ez-builder to obtain assistance with that control, including activities and tutorials. The camera control has many tutorials. Here is a direct link to the camera control manual page: http://www.ez-robot.com/Tutorials/Help.aspx?id=80

Enjoy the learn section! Have fun with the robot program
