How to store temporary bufferedImage during scaling in java graphics

Question

I want to scale a large 1920x1080 buffered image into smaller 200x200 size using progressive bicubic approach. I start with the 1024x768 and scale down to nearly 80% of original and then want to store this temp image somewhere in some format so that in next iteration i perform again the scaling to 80% on this image and continuing the procedure till i obtain 200x200 image which i finally display on my JFrame.

WHAT IS THE METHOD OR WAY TO STORE THIS TEMP IMAGE?OR CAN ANYONE SUGGEST A SIMPLE APPROACH TO IMPLEMENT THIS PROGRESSIVE BICUBIC SCALING.

The expected code looks similar to this(though it needs various modifications ,i need just the way to store temp image)

int sizew=1920,sizeh=1080;
    int deltaw = (int)(0.20 *1920);
    int deltah= (int)(0.20*1920);
    while(sizew>200&&sizeh>200)
    {
        sizew=sizew-deltaw;
        sizeh=sizeh-deltah;
        if(sizew<200||sizeh<200)
        {
            sizew=200;
            sizeh=200;
            temp=new BufferedImage(sizew,sizeh,BufferedImage.TYPE_INT_RGB);
                    //but using this how would i give reference to my original 1920x1080 image or temp image???
            break;
        }
        else
            temp=new BufferedImage(sizew,sizeh,BufferedImage.TYPE_INT_RGB);
    }

Madam, sentences with all capital letters are hard to read (and the equivalent to shouting :-) — kleopatra, Oct 26 '12 at 14:58

No easy task; here's an outline of the brute-force approach:

Tile the image into manageable pieces using an available approach suited to the source, for example

Java getSubImage(), seen here.
Ossim, designed for geodetic data, but usable for imagery.

Resample the tiles as warranted by the intended use, for example

AffineTransform, seen here, using TYPE_NEAREST_NEIGHBOR.
ImageJ, which may be scripted.

Reassemble the tiles; the approach depends on the destination.
