Hi guys so i have a array of 12bit values that im getting via serial i am storing that data in an 2D array and based on the reading i get i display it as a pixel on the screen 0 - black, 4095 - White. my 2d Array is [16][8] what i would like to use bicubic interpolation on these matrix with a factor 10 how would i go about doing that? below is my test code. parssedData[][] is the 2d array i use to generate the the image on screen.

Basically what i would like to do is interpolate this array using the interpolation() function within openCV and generate the interpolated image on screen.

//OPTOSENSOR.CLASS

Serial dataPort; //create object from serial class
/*Setup Java fullscreen*/

/*2D Array of objects*/

/*Number of columns and rows in the grid*/
int cols = 16; // number of columns
int rows = 8; // number of rows
/*Parssed data array*/
//int [][] parssedData = new int [rows][cols];
// Parssed Data test array
int[][] parssedData = { {255, 189, 189, 0, 236, 189, 189, 0, 0, 189, 189, 0, 236, 189, 189, 0},

Code for Cell Class

// A Cell object
class Cell {
// A cell object knows about its location in the grid as well as its size with the variables x, y, w, h.
float x,y; // cell x,y location
float w,h; // cell width and height
float data; // data for cell brightness
// Cell Constructor
Cell(float tempX, float tempY, float tempW, float tempH, float tempData) {
x = tempX;
y = tempY;
w = tempW;
h = tempH;
data = tempData;// * 0.0622;
}
void display() {
//stroke(100);
// Color calculated based on live data
colorMode(RGB, 12);
smooth();
noStroke();
if (data > 3)
{
fill(data);
}
else
{
fill(0);
}
//rect(477+x,235.5+y,w,h);
rect(1+x,1+y,w,h);
println(data);
}
}
