Method

BufferedImagefilterSmooth(BufferedImage img)
filter Smooth 
final int SSIZE = 3;
int x, y, i, j, val;
int r;
final int w = img.getWidth();
final int h = img.getHeight();
final BufferedImage newImg = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB);
for (y = 0; y < h; y++) {
    for (x = 0; x < w; x++) {
...
BufferedImagefilterThreshold(BufferedImage img, int threshold)
filter Threshold 
final int w = img.getWidth();
final int h = img.getHeight();
final BufferedImage newImg = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB);
Color min = Color.BLACK;
Color max = Color.WHITE;
if (threshold < 0) {
    min = Color.WHITE;
    max = Color.BLACK;
...
inthorizontalFilter(BufferedImage bufImg, int startX, int stopX, int start, int stop, int y, double[] pContrib)
horizontal Filter 
double valueRed = 0.0;
double valueGreen = 0.0;
double valueBlue = 0.0;
int valueRGB = 0;
int i, j;
for (i = startX, j = start; i <= stopX; i++, j++) {
    valueRGB = bufImg.getRGB(i, y);
    valueRed += getRedValue(valueRGB) * pContrib[j];
...
BufferedImagethresholdFilter(int threshholdLevel, BufferedImage image)
Create the filter to execute a threshold setting on the color component values. 
short[] threshold = new short[256];
for (int i = threshholdLevel; i < 256; i++)
    threshold[i] = (short) i;
LookupTable threshold_table = new ShortLookupTable(0, threshold);
LookupOp threshold_op = new LookupOp(threshold_table, null);
return threshold_op.filter(image, image);
BufferedImageverticalFiltering(BufferedImage pbImage, int iOutH)
vertical Filtering 
int iW = pbImage.getWidth();
int iH = pbImage.getHeight();
int value = 0;
BufferedImage pbOut = new BufferedImage(iW, iOutH, BufferedImage.TYPE_INT_RGB);
for (int y = 0; y < iOutH; y++) {
    int startY;
    int start;
    int Y = (int) (((double) y) * ((double) iH) / ((double) iOutH) + 0.5);
