Method Details

createLaplacian

public static <T extends ImageGray<T>>
ImageFunctionSparse<T> createLaplacian(Class<T> imageType,
 @Nullable
 @Nullable ImageBorder<T> border)

Creates a sparse Laplacian filter.

Parameters:

imageType - The type of image which is to be processed.

border - How the border should be handled. If null BorderType.EXTENDED will be used.

Returns:

Filter for performing a sparse laplacian.

Creates a sparse sobel gradient operator.

Parameters:

imageType - The type of image which is to be processed.

border - How the border should be handled. If null then the borders can't be processed.

Returns:

Sparse gradient
