#Know Your Cards
Recognize playing cards using Windows Phone as a client and Microsoft Asp.net WebApi as a server . The project is inspired from Nazmi Altun and his article on codeproject that is currently unavailable.
Projects
There are 2 projects here, the one would be ImageUploader and ImageUploadServer.
- ImageUploader is a simple Windows Phone app that takes a picture from gallery and uploads it. If you want a CameraCaptureTask, feel free to upload it.
- ImageUploadServer takes the image, uses Aforge.net and with a little basic template matching he processes the image and gets you the playing cards name.
(I will write a full description on how it works soon here)
#Ways to use it: ####Binding your IP in IIS Express
- Find IIS Express configuration file, applicationhost.config, in the folder %USERPROFILE%\Documents\IISExpress\config\
- Duplicate the line, and replace “localhost” with your IP address (make sure to verify the port number). Save the file.
- At this point, you should be able to run the web service and on the browser, go to the /fileupload using your IP address and port instead of localhost. However, that works only from the browser.
Note: you might not be able to reach out the endpoint with your IP address. If that is the case, completing the following steps, and re-running the web service should fix it.
####Allow Incoming Connections
If you try to reach the endpoint on your browser using the IP address, you will most likely get a Bad Request or Service Unavailable response, since up to this point the firewall is not allowing incoming connections.
- Start a command prompt with administrative privileges.
- Run the following command making sure to include your IP address and the correct app port:
netsh http add urlacl url=http://youripaddress:yourappport/ user=everyone.This just tells http.sys that it’s ok to talk to this url. - Add a rule in the Windows Firewall, allowing incoming connections to your app port for computers on your local subnet. To do so, run the following command including the correct port.
netsh advfirewall firewall add rule name="IISExpressWeb" dir=in protocol=tcp localport=yourappport profile=private remoteip=localsubnet action=allow
If you open the Windows Firewall manager, you should be able to see the new rule added. You can change or delete the rule from here easily.
###Change the ip on the app Go over MainPage.xaml.cs and UploadFile() method and change the following line to your server api
var fileUploadUrl = @"http://10.211.10.190:60662/api/file";
###Bugs
- Cant detect cards if they are put on one over another
- Usually works best if a dark colored background is provided
###Updates that are coming
- Multiple card recognition
- Card boundary visbility
Let me know how you guys like it and have fun!
