Thanks again berak :D

2016-12-28 01:24:17 -0500 asked a question How to create Mat from rgb 2d arrays?????

Mat om=new Mat();

double[] rx=new double[3];

for(int i=0;i< sizeA.height;i++)

{

for(int j=0;j< sizeA.width;j++)

{

        rx[0]=r3[i][j];

        rx[1]=g3[i][j];

        rx[2]=b3[i][j];

        om.put(i, j, rx);

}

}

I am using this code but I am not getting any output for the given code.

r3,g3 and b3 are the rgb arrays & sizeA is Size of the Mat.

2016-12-27 00:50:16 -0500 asked a question I am converting Matlab code in to java code, Plz Help me with some matlab functions and tell equivelent java function.

rgbfcm=cast(o,class(y)); redPlane = y(:, :, 1).rgbfcm; greenPlane =y(:, :, 2).rgbfcm; bluePlane = y(:, :, 3).*rgbfcm; fcmrgb = cat(3, redPlane,greenPlane, bluePlane);

Please tell me how to use these functionalities in Java.......

Mat im= Imgcodecs.imread(d);
Mat inp=new Mat();
Mat newinp=new Mat();
inp.convertTo(newinp, CvType.CV_64F);
java.util.List<Mat> rgb=null;
Core.split(newinp, rgb);
