I'm looking to grab frames from the Camera without a preview as I want to use the output frames within a Cordova App (on Android, iOS and Windows Phone) as Cordova Apps are restricted to using a WebView. Can I use OpenCV for this (and more naturally!).
Thanks in advance! //Adam
If you don't want to preview the input frames, you just have to return null in the "OnCameraFrame" method.
It's look look this:
public Mat onCameraFrame(CvCameraViewFrame inputFrame) {
return null;
}
And vise versa, if you want to do some manipulation on the input frames and show them just change the retun matrix as you want.
Marvellous! Thanks. Where should I go for some sample code so I can hit the ground running?
You can start here: http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/dev_with_OCV_on_Android.html roll down to "Hello OpenCV Sample"
If you mean with without a preview, that you don't show the images, then sure! Basically a simple "hello world" type of application for opencv would be :
If you omit the last step, then I suppose you have what you are looking for.
