Method Detail

computeSuppressed

public static FImage computeSuppressed(FImage dxImage,
                                       FImage dyImage)

Perform non-maximum suppression.

Parameters:

dxImage - x-gradients

dyImage - y-gradients

Returns:

non-maximum suppressed magnitude image.

computeSuppressed

public static FImage computeSuppressed(FImage dxImage,
                                       FImage dyImage,
                                       FImage magsOut)

Perform non-maximum suppression.

Parameters:

dxImage - x-gradients

dyImage - y-gradients

magsOut - an image with the same dimensions as dxImage and dyImage for holding the magnitudes before non-maximum suppression. May be null.

Returns:

non-maximum suppressed magnitude image.

combine

public FImage combine(FImage dxImage,
                      FImage dyImage)

Perform non-maximum suppression.

Specified by:

combine in interface ImageCombiner<FImage,FImage,FImage>

Parameters:

dxImage - x-gradients

dyImage - y-gradients

Returns:

non-maximum suppressed magnitude image.
