Kinect, object recognition and Emgu (+openCV)

13:11 Posted by Jon Carlos , , , , 3 comments
I've been posting a few things about kinect reciently and doing some experiments with webcams and object recognition. I just thought i'd post a few links to some of the things I've found.

But first off some more cool kinect stuff.

Kinect Skeleton Test
Kinect Mashup

So i was looking at how you do object recognition and thankfully there are some very cool open source or free libraries out there that help.

OpenCV is a computer vision library with over 500 algorythems for managing computer vision.

I code in C# so I needed a library to help working with OpenCV. I found a couple of EMGU turned out to be the most straightforward to work with.

I'f you'd like to train your system to recognise faces or what ever then you'll need some help there too. Haartraining is what your looking for, although I've not got this working yet!

Please post a comment if you have any suggestions on the Haartraining stuff. I'd like to get this working.

SocialFront for Umbraco Launch!

22:18 Posted by Jon Carlos , , , No comments
Wow, we made it.

After 3 3.5 4 days of development and a few hours here and there we've finally made it the launch of our first release of SocialFront.

Personally I'd like to thank David for all his help. Those of you that have been following the project will know I've been working with David over the last few month to make this happen and without him it would not have been possible or as quick! Ross for working on the styles (Not quite finished!).

I'd also like to thank the the Umbraco community who are one of the friendliest I've come in contact with. These fantastically positive people and their blogs which I've been using over and over have been a constant inspiration on what we've done in SocialFront.

Big thanks go to Screenmedia for allowing us to camp out in the meeting room on Saturdays while developing SocialFront.

Finally my wife for putting up with me ;-)

Where do I get SocialFront?

SocialFront for Umbraco Day 3 - The PM!

20:01 Posted by Jon Carlos , , 1 comment
So after a great lunch at our favourite local pub Chinaski's we put the issues we had in the morning behind us and started to hack our way around packaging issues and how to install SocialFront on Umbraco.

15:00

Jon started to look at the possibilities of editing the umbraco core so we could fix the issues with exporting document types but as we did not know the Umbraco code base too well decided after about half an hour that it would probably be best just to manually edit the package.xml

This took a little time but was not too much of a hassell so by about 16:00 we had a package that we had tested on a couple of Umbraco installations.

During this time David was making good progress on coding the install mechanism so once the package contents were installed the user would be able to just click a button and they would have a ready built community setup.

17:00

David was continuing to work on the code to do the install so I started to work on exactly how we were going to edit the web.config to add all the SocialFront providers that are required.

I found a post on StackOverflow that seemed to do what I was need but found it a little hard to follow then I found an article on MSDN that was exactly what I needed.

I had to extend the number of properties in SocialFrontProviderConfiguration for me to be able to populate the web.config properly but then all I needed to do open up the web.config programmatically then add the SocialFront provider sections:

Configuration config = WebConfigurationManager.OpenWebConfiguration("~");
SocialFrontProviderConfiguration configuration = new SocialFrontProviderConfiguration();
configuration.Name = "name";
configuration.Default = "Umbraco";
configuration.Providers.Add(new ProviderSettings("name", "type"));
config.Sections.Add(configuration.Name, configuration);
config.Save();


As we were using xml for the setup of the site structure I figured that I would also setup the provider definitions using the same technique. So I created an xml config file to enumerate through that meant we could add any providers we needed at runtime when SocialFront was installed on a site.

18:30

Unfortunatley we were unable to get our package created by the end of the day. We're not far away from having it ready so we've decided that we're going to meet again this week and finish the installer and get the package release before the end of the week.

So after a hard day of planning and coding we made our way to the pub for a quick pint and to reflect on the day.

SocialFront Testers

As with any project SocialFront needs testing and we're looking for some people to give us some feedback on what we've done and make suggestions on how to make it better. If you have any time you can give us to install our new package then we'd love to hear from you. Please email me and I'll email you as soon as the package has been released.

We've also setup a uservoice site for SocialFront feedback, suggestions and bugs if you could put any ideas you have there we'll review suggestions and get to work ;-)

Social Front for Umbraco Day 3 - The AM!

12:02 Posted by Jon Carlos No comments
So we've started Dev Day 3 on Social front.

9.30

So this morning we've been planning the install procedure for the Umbraco package, discussing how we've going to manage names of files, alias names, macro names and drinking tea.

Having discussed all this stuff so far we've found that it's not quite as simple as all that and now we're getting down to the hard work of coding up some custom install functionality.

12:30

So far we've created a package for the site and found a couple of bugs in the package setup system. The bugs are more gotchas in the export function, I've listed them here so you can vote them up ;-)

Talking about Central Station at Glasgow TechMeetup

I just wanted to do a quick update as I'm speaking at the Glasgow TechMeetup on Jan 27th 10. It's a very short introduction to how we build Central Station

I'm going to show a couple of little things we did that are quite cool, like how we converted the standard KickApps Member Profile pages from the standard to what we have.

There will also be a quick overview of Umbraco the open source CMS we use at Screenmedia

Anyway if you're in Glasgow need some food and drink(Free Pizza & beer) come see us at:
TechMeetup #8
Kick-off at 7pm, finishing at 10pm.
Ground floor of the Saltire Building.
Glasgow Caledonian University

Also speaking is Jay Jagpal he'll be talking about Adobe Flash & Flex, how it can be used today and how it will drive iPhone and multitouch development tomorrow.
