Hi berak, I tried your suggestion, but still my app is getting crashed.

Hello Everyone.

I'm developing an Image processing app in Android using OpenCV library. I want to convert the color image into grayscale, when user selects image from the SD card. I've used the below code -

        Bitmap b = BitmapFactory.decodeFile(picturePath);
        Mat tmp = new Mat (b.getWidth(), b.getHeight(), CvType.CV_8UC1);
        ImageView imgView = (ImageView) findViewById(R.id.imgview2);
        Utils.bitmapToMat(b, tmp);
        Imgproc.cvtColor(tmp, tmp, Imgproc.COLOR_BGR2GRAY,0);            
        Utils.matToBitmap(tmp, b);
        imgView.setImageBitmap(b);

there is no compile time error in this code. But when I run this app in my smartphone, the app gets crashed and sends an messsage as - unfortunately the app stopped working. Kindly provide me the correct code to solve this issue. Thank you in advance.

Hello everyone.

I'm developing an Android application for image processing using OpenCV concepts in Eclipse Luna. I'm a newbie in this stream. Please provide me the steps of adding OpenCV library in Eclipse Luna. Thank you in advance.

Hello everyone.

I'm new to image proccessing concepts. I've developed an image processing application on C#.Net platform using Emgu CV wrapper classes and I've deployed it on Microsoft Azure Cloud. When I run my application on Azure cloud i'm getting following error as : -

Error Stack Trace -

at Emgu.CV.CvInvoke.cvCreateImageHeader(Size size, IPL_DEPTH depth, Int32 channels) at Emgu.CV.Image2.AllocateData(Int32 rows, Int32 cols, Int32 numberOfChannels) at Emgu.CV.Image2.set_Bitmap(Bitmap value) at NnSmAzWebRole._Default.BtnProcs_Click(Object sender, EventArgs e)

Error Message -

The type initializer for 'Emgu.CV.CvInvoke' threw an exception.

But when I run the same application locally at my PC it is running smoothly. I've uploaded all the necessary Emgu CV & OpenCV DLL's on Azure cloud same as what i use to locally run the application on my PC. Please provide me some solutions to solve this problem. Thank you in advance.
