I want to make an application that opens up camera, point at an image and if the image is recognized in my database, give all the corresponding info, else, nothing happens. I dont know where to start, can you give me orientation and specify what cross-platform / ios / android language should I use?
You can try OpenCV. Check for similarities to match database image and camera view. take a look at following link. similar post described there:

I have an application which could easily be controlled by a bot over network or even on the local machine(which simuates keyboard and mouse e.g.).
I want to avoid this using a captcha. The source has to work without internet / has to be generated during runtime on the computer itself.
Is there any open-source project for this or can someone give me a code example or a link ?
I've found an article "Simple CAPTCHA, Create your own in C#" by Raymund Macaalay. It is for an ASP.NET app, but he generates a normal C# bitmap image using different random fonts in STEP2, so this should also work in your WinForms app.

I'm looking for a graph API (open source or to buy) - that enables to draw bubbles graph from input data - but the twist is that I want the bubbles to be pictures (gif,JPEG etc.) that I'll inject (instead of bubbles) - and the pictures will be in the size of the bubble (some pictures will be relatively small others are relatively big according to the input data).
Is there such kit?
Thanks.
As eboix comments, org.jfree.chart.renderer.xy.XYBubbleRenderer would be a good starting point, although you'd have to override drawItem().

I am looking for a .net control that allows for the editing of images. The following features would be desirable:
Crop
Zoom
Pen
Line
Brush
Circle
Polygon
Full undo / redo
Measure Tool
Layers(not critical)
This control can either be Winforms or WPF, but would need to be extensible.
I am happy for it to be a commecial control or open source. If source code is also available C# is desired.
I ended up finding that an "Image annotation" control satisfied all of my needs.
I went with VintaSoftAnnotation.NET Plug-in
In my research I found others:
leadtools
atalasoft dotimage
accusoft imagegear
This would help :

is there any world map (on web) that can give me x,y coordinates
for any place in the world ?
(i build Windows-mobile GPS program and i need to check it)
thank's in advance
http://maps.google.com/
Center the map, then click link in the top right. The lat/lng is in the url as the ll parameter
Google maps would let you lookup or check coordinates from your program. Here is a good article that can detail how to obtain the coordinates inside Google Maps:
http://www.online-tech-tips.com/computer-tips/find-longitude-latitude/
A few different methods are described in there.

i was wondering if anyone knows of any gps receivers that have a fairly good API..
I am hoping to develop a simple app that will show my location (live) on google maps using the google maps api but of course would need an recevier that i can interface with too whilst on the move.
Cheers.
NB: Work would be done in c#.
Most still provide a serial connection. Coordinates would be coming in ASCII format, and that is super-easy to process.
