Method Detail

gaussianBlur

public static void gaussianBlur(ImageDescriptor src,
                ImageDescriptor dst,
                double sigma)
                         throws java.lang.Exception

Apply a gaussian blur on a 2D or 3D image.

Parameters:

src - The input image

dst - The output image. Must have the same size as src.

sigma - Standard deviation of the gaussian filter.

Throws:

java.lang.Exception - Throw an exception if src and dst have not the same size.

gradient

public static void gradient(ImageDescriptor src,
            ImageDescriptor Fx,
            ImageDescriptor Fy,
            ImageDescriptor Fz)
                     throws java.lang.Exception

Compute the gradient of an image.

Parameters:

src - The input image

Fx - Derivative along the x direction.

Fy - Derivative along the y direction.

Fz - Derivative along the z direction if it's a 3D image.

Throws:

java.lang.Exception - Throw an exception if src, Fx, Fy (and Fz) have not the same size.

gradientDirection

public static void gradientDirection(ImageDescriptor Fx,
                     ImageDescriptor Fy,
                     ImageDescriptor Fz,
                     ImageDescriptor Alpha,
                     ImageDescriptor Beta,
                     ImageDescriptor Gamma)
                              throws java.lang.Exception

Compute the gradient direction.

Parameters:

Fx - Derivative along the x direction.

Fy - Derivative along the y direction.

Fz - Derivative along the z direction if it's a 3D image.

Alpha - Orientation of the gradient from x and y directions.

Beta - Orientation of the gradient from z and y directions.

Gamma - Orientation of the gradient from x and z directions.

Throws:

java.lang.Exception - Throw an exception if the images have not the same size.
