Method Summary
static BinaryFast dilate_image(BinaryFast binary, int[] kernel, int iterations)
          Takes a BinaryFast image, a kernel and the number of iterations and performs the necessary number of dilations on the image.
static BinaryFast dilateSingleIteration(BinaryFast binary, int[] kernel)
          Takes a BinaryFast representation of an image and a kernel and applies a single iteration of the dilate algorithm.
static boolean kernelAll1s(int[] kernel)
          Returns true if the kernel consists of 9 1s.
static boolean kernelMatch(java.awt.Point p, int[][] pixels, int w, int h, int[] kernel)
          Takes a point and a 2D array representing an image and a kernel, if the area around the point matches the kernel then the method returns true.

Method Detail

kernelMatch

public static boolean kernelMatch(java.awt.Point p,
                                  int[][] pixels,
                                  int w,
                                  int h,
                                  int[] kernel)
Takes a point and a 2D array representing an image and a kernel, if the area around the point matches the kernel then the method returns true.
Parameters:
p - The point in the centre of the neighbourhood to be checked.
pixels - The 2D array representing the image.
w - The width of the image.
h - The height of the image.
kernel - The kernel used to match with the image.
Returns:
True or false (true - the kernel and image match).

kernelAll1s

public static boolean kernelAll1s(int[] kernel)
Returns true if the kernel consists of 9 1s.
Parameters:
kernel - The array representing the kernel.
Returns:
True or false (true - kernel all 1s).

dilateSingleIteration

public static BinaryFast dilateSingleIteration(BinaryFast binary,
                                               int[] kernel)
Takes a BinaryFast representation of an image and a kernel and applies a single iteration of the dilate algorithm.
Parameters:
binary - The BinaryFast representation of the input image.
kernel - The array representing the kernel.
Returns:
The BinaryFast representation of the new image after dilation.

dilate_image

public static BinaryFast dilate_image(BinaryFast binary,
                                      int[] kernel,
                                      int iterations)
Takes a BinaryFast image, a kernel and the number of iterations and performs the necessary number of dilations on the image.
Parameters:
binary - The BinaryFast representation of the input image.
kernel - The array representing the kernel.
iterations - The requested number of iterations.
Returns:
The BinaryFast representation of the new image after dilation.
