                             double offset)
Takes an input image and applies the required laplacian smoothing and returns the output image.
Parameters:
input - The input image integer array.
width - The input image width.
height - The input image height.
kernel - The kernel type selected, 1,2 or 3.
scale - the scale factor for the output pixel values
offset - the offset value for the output pixel values
Returns:
The output image integer array.
