image-capture

I am capturing the image using OpenCV in C++ firstFrame = cvQueryFrame(capture); it is easy to set the width and height properties by cvSetCaptureProperty( capture, CV_CAP_PROP_FRAME_WIDTH, WIDTH ); cvSetCaptureProperty( capture, CV_CAP_PROP_FRAME_HEIGHT, HEIGHT ); I wonder if there is a way to specify the color depth as well without further processing the frame? According to the documentation , you should be able to do it using CV_CAP_PROP_FORMAT if you use the function retrive() to get your frame. CV_CAP_PROP_FORMAT Format of the Mat objects returned by retrieve() . However, notice also that

I want my app to be able to capture photos without using another application. The code i used : Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); File photo = null; try { photo = this.createTemporaryFile("picture", ".jpg"); photo.delete(); } catch(Exception e) { Toast.makeText(getApplicationContext(),"Error",Toast.LENGTH_LONG).show(); } mImageUri = Uri.fromFile(photo); intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri); startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE); But this code uses the phone's main camera app. Can anyone give me some code ? Taking a picture

I'm trying to get as good an image as possible from the camera, but can only find examples that captureStillImageAsynchronouslyFromConnection and then go straight to: NSData *imageData = [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageSampleBuffer]; UIImage *image = [[UIImage alloc] initWithData:imageData]; JPEG being lossy and all, is there any way to get the data as PNG, or even just RGBA (BGRA, what-have-you?). AVCaptureStillImageOutput doesn't seem to have any other NSData* methods.... Actually looking at the CMSampleBufferRef, it seems like it's already locked as JPEG ~

How can i make screenshoots to the entire game screen very fast? Somthing like 20-30 per second?(i want to convert them to video) [[1]] I've tried WMEncoder.Results were that WMEncoder can capture the screen and regions of screen only in a video format (wma) using a set of preconfigured codecs. (29 fps best encode result).WMEncoder can not make screenshots. [[2]] I've tried DirectX : Surface s = device.CreateOffscreenPlainSurface( Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, Format.A8R8G8B8, Pool.SystemMemory); device.GetFrontBufferData(0, s); SurfaceLoader.Save("c:\

I want to be able to create a screen shot of a given Web site, but the Web site may be larger than can be viewed on the screen. Is there a way I can do this? Goal is to do this with .NET in C# in a WinForms application. There are a few tools. The thing is, you need to render it in some given program, and take a snapshot of it. I don't know about .NET but here are some tools to look at. KHTML2PNG imagegrabwindow() (Windows PHP Only) Create screenshots of a web page using Python and QtWebKit Website Thumbnails Service Taking automated webpage screenshots with embedded Mozilla I just found out

When use use getPicture either we get a relative URL or base64image. But I want to send a image object to Amazon S3. Anyway to do that ? Here is how I am getting the base64image // A button will call this function // function capturePhoto() { // Take picture using device camera and retrieve image as base64-encoded string navigator.camera.getPicture(onPhotoDataSuccess, onFail, { destinationType: Camera.DestinationType.DATA_URL, quality: 50 }); } [UPDATE] Now I need to get the image as object convert it to byte array and upload it to Amazon S3 using REST (PUT) call. sure you can camera/image

Can anybody help me in this? I want to get an screenshot from an video playing through MPMediaPlayerController. What i have tried so far is:- -(void)viewDidLoad { NSURL *tempFilePathURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"LMFao" ofType:@"mp4"]]; player = [[MPMoviePlayerController alloc] initWithContentURL:tempFilePathURL]; [player setControlStyle:MPMovieControlStyleFullscreen]; //Place it in subview, else it won’t work player.view.frame = CGRectMake(0, 0, 320, 400); [self.view addSubview:player.view]; } -(IBAction)screenshot { CGRect rect = [player.view bounds];

I want to capture a single image from my webcam and save it to disk. I want to do this in Java or Python (preferably Java). I want something that will work on both 64-bit Win7 and 32-bit Linux. EDIT: I use Python 3.x, not 2.x Because everywhere else I see this question asked people manage to get confused, I'm going to state a few things explicitly: I do not want to use Processing I do not want to use any language other than those stated above I do want to display this image on my screen in any way, shape or form I do not want to display a live video feed from my webcam on my screen, or save
