Method Detail

erode4

public static void erode4(GrayU8 input,
                          GrayU8 output)

dilate4

public static void dilate4(GrayU8 input,
                           GrayU8 output)

edge4

public static void edge4(GrayU8 input,
                         GrayU8 output)

erode8

public static void erode8(GrayU8 input,
                          GrayU8 output)

dilate8

public static void dilate8(GrayU8 input,
                           GrayU8 output)

edge8

public static void edge8(GrayU8 input,
                         GrayU8 output)

removePointNoise

public static void removePointNoise(GrayU8 input,
                                    GrayU8 output)

Binary operation which is designed to remove small bits of spurious noise. An 8-neighborhood is used. If a pixel is connected to less than 2 neighbors then its value zero. If connected to more than 6 then its value is one. Otherwise it retains its original value.

Parameters:

input - Input image. Not modified.

output - If not null, the output image. If null a new image is declared and returned. Modified.

getT

public static boolean getT(GrayU8 image,
                           int x,
                           int y)

If a point is inside the image true is returned if its value is not zero, otherwise true is returned.

getF

public static boolean getF(GrayU8 image,
                           int x,
                           int y)

If a point is inside the image true is returned if its value is not zero, otherwise false is returned.
