webcam

I am using Opencv for some real-time video processing. As a front-end I am using QT framework. On my GUI, I have an input image window (mapped to a Label) and an output image window (mapped to another Label) and 3 push buttons. One to Start input video capture, the second to process the video (code not written yet), and third to Exit. I am currently able to stream my video and display it on the Front-end. But this locks my GUI and am unable to Exit. I tried using QTimers (using suggestions from this and the QT forum), but my GUI still remains locked. Would appreciate if someone can point my in

has anyone gotten this http://www.xarg.org/project/jquery-webcam-plugin/ , to work with aps.net mvc 3? I can't seem to decode the image, using the WebImage class or BitmapImage. I've tired to do this with Silverlight, but I'm really unsure on how to upload the image. I do not need to save the image, I just want to process it, what im really looking to do is read a bar-code via web app. I just can't seem to find a good guide to uploading an image from Silverlight or flash to my MVC app. Thanks in advance. The documentation contains many examples. All that's needed is to read and try out. So

im having a hard time saving the image captured from the webcam using the jquery webcam plugin. here's the code.. $(document).ready(function(){ $("#camera").webcam({ width: 320, height: 240, mode: "save", swffile: "jscam.swf", }); }); i am using the 'save' mode. in the body part.. <div id="camera"></div> <a href="javascript:webcam.save('upload.php');void(0);">capture</a> in the upload.php part.. $str = file_get_contents("php://input"); file_put_contents("upload.jpg", pack("H*", $str)); i also tried the callback mode still doesnt work. it seems the blog itself has insufficient examples http:/

I am trying to write a program in Visual Studio 2008 that will access a webcam, show a preview on the screen and then save a still snapshot (.jpg) when the button is pushed. Later I am going to integrate it with a database, but I shouldn't have a problem with that part. After doing some research, it looks like DirectShow is the best bet, because WIA didn't work on the camera I had (and I'm not sure it will continue to work into the future). Preferably, I need my solution to work from Windows XP to Windows 7. I have never used DirectShow (or similar) before. One problem I am running into is

I am working on an ASP.Net application and I want users to be able to take a picture with their local webcam and then upload it to the server. I can, of course, rely on users doing this manually via their locally installed software, save the image as a file and do a normal file upload. However, what I really want to do is incorporate it all into a UI in the browser. I know this means accessing local resources so do I need an ActiveX control or Silverlight or is there something I could do in Javascript for example? This is initially intended for an Intranet app so I can have control of the
