Method Detail

pixelSubtraction

public static int[] pixelSubtraction(int[] pixels1,
                                     int[] pixels2)
Subtracts each pixel in pixels2 from the corresponding pixel in pixels1.
Parameters:
pixels1 - the first array of pixels
pixels2 - the array to subtract from the first
Returns:
the resulting array of pixels

pixelAddition

public static int[] pixelAddition(int[] pixels1,
                                  int[] pixels2)
Adds each pixel in pixels2 to the corresponding pixel in pixels1.
Parameters:
pixels1 - the first array of pixels
pixels2 - the pixels to add to pixels1
Returns:
the resulting array of pixel values

pixelMultiplication

public static int[] pixelMultiplication(int[] pixels,
                                        double k)
Multiplies each pixel in pixels with the constant.
Parameters:
pixels - the array of pixels
k - the multiplication constant
Returns:
the new array

unsharp_image

public static int[] unsharp_image(int[] input,
                                  int width,

Parameters:
input - the input image array
width - of the image
height - of the image
k - the unsharp constant
Returns:
the new image array
