Problems with use of memory on HelloARCSharp.

I am tring to get the image projection matrix on the HelloARCSharp example. This is the code that I wrote:

var frame = oFrame.Value.AddToAutoRelease(ar);
if (!frame.inputFrame().hasCameraParameters()) { return; }

var image = frame.inputFrame().image();
var width = image.width();
var height = image.height();

var cameraParameters = frame.inputFrame().cameraParameters();
float viewportAspectRatio = (float)width / (float)height;
Matrix44F imageProjection = cameraParameters.imageProjection(viewportAspectRatio, screenRotation, true, cameraHorizontalFlip);

I believe that I have to release an object because the use of memory increase linearly.

I tried to add to AutoRelease the image or cameraParameters but it doesn't work.

Can anyone help me, thank you.

Dispose everything that are disposable when goes out of scope.

And try not cascade like frame.inputFrame().cameraParameters(), you are missing a chance to dispose InputFrame.
