Method Detail

getKernelX

public static Kernel2D getKernelX(boolean isInteger)

Returns the kernel for computing the derivative along the x-axis.

process

public static void process(ImageUInt8 orig,
           ImageSInt16 derivX,
           ImageSInt16 derivY,
           ImageBorder_I32 border)

Computes the derivative in the X and Y direction using an integer Prewitt edge detector.

Parameters:

orig - Input image. Not modified.

derivX - Storage for image derivative along the x-axis. Modified.

derivY - Storage for image derivative along the y-axis. Modified.

border - Specifies how the image border is handled. If null the border is not processed.

process

Parameters:

orig - Input image. Not modified.

derivX - Storage for image derivative along the x-axis. Modified.

derivY - Storage for image derivative along the y-axis. Modified.

border - Specifies how the image border is handled. If null the border is not processed.

process

           ImageFloat32 derivX,
           ImageFloat32 derivY,
           ImageBorder_F32 border)

Computes the derivative in the X and Y direction using a floating point Prewitt edge detector.

Parameters:

orig - Input image. Not modified.

derivX - Storage for image derivative along the x-axis. Modified.
