webcam

We have a c# application that performs processing on video streams. This is a low-level application that receives each frame in Bitmap format, so basically we need 25 images each second. This application is already working for some of our media sources, but we now need to add a webcam as an input device. So we basically need to capture bitmap images from a webcam continuously so that we can pass all these frames as a "stream" to our application. What is the best and simplest way to access the webcam and read the actual frames directly from the webcam as individual images? I am still in the

I am working on a project which I need to synthesize a video from existing frames and then format it exactly like a webcam device and make it available to external computers. In other words, this USB output should look exactly as if it was generated by a webcam. Can someone provide some hints about any existing library or any methodology to do this? The target system to create "webcam" output via USB is UBUNTU. Thanks Web cams are usually accessed through a library or the operating system rather than as low level USB devices. In python, one option to read webcam frame is https://github.com

I'm using WIALib to access my webcam. The code I'm developing is pretty simple: when a button is pressed a webcam picture is taken, and then displayed in a picture box. I can already take pictures with my webcam, but it isn't yet fully automated. The only way I found to retrieve the pictures taken by the webcam, is using this: wiaPics = wiaRoot.GetItemsFromUI( WiaFlag.SingleImage, WiaIntent.ImageTypeColor ) as CollectionClass; But this asks the user to select the picture. And I always want the last picture taken. So I'm trying this way: string imageFileName = Path.GetTempFileName(); // create

Taking reference from this article on HTML5Rocks I am trying to build a utility to take photo from webcam. Below is my HTML code snippet: <button type="button" name="btnCapture" id="btnCapture">Start my camera</button><br /> <video autoplay="true" id="video" style="height:240px;width:320px"></video><canvas id="canvas" style="display: none; height:240px;width:320px"></canvas><br /> <img id="capturedImage" src="/blank.gif" style="height:240px;width:320px"><input type="hidden" id="hdnImageBase64" name="hdnImageBase64"><br /> On click of button btnCapture I start my webcam and clicking it again It

I am very happy that I got the opportunity to work on a website that is gesture-based. I have a few inspiration for this: link I visited lot of websites and googled it, Wikipedia and gitHub also didn't help much. There is not much information provided as these technologies are in nascent stages. I think I will have to use some js for this project gesture.js (our custom javascript code) reveal.js (Frame work for slideshow) My questions are how come gestures generate events, how does my JavaScript interact with my webcam? Do I have to use some API or algorithms? I am not asking for code. I am

I have been trying to create a tkinter top level window that streams video form webcam and do a QR scan. I got this QR scan code from SO and another code that just updates images from webcam instead of streaming the video on a tkinter label. and i tried to combine these both so that a toplevel window with a label updating image from webcam and a close button to close the toplevel window. And while it streams the images, it can scan for QR code and if a scan is successful, the webcam and the toplevel window gets closed. here is what i tried. import cv2 import cv2.cv as cv import numpy import
