Description copied from interface: GeneralFeatureIntensity

Computes the corner's intensity. Before computing the various image derivatives call GeneralFeatureIntensity.getRequiresGradient() and GeneralFeatureIntensity.getRequiresHessian() to see if they are needed.

Parameters:

image - Original input image

derivX - First derivative x-axis

derivY - First derivative x-axis

derivXX - Second derivative x-axis x-axis

derivYY - Second derivative x-axis y-axis

derivXY - Second derivative x-axis y-axis

getCandidatesMin

@Nullable
public @Nullable ListIntPoint2D getCandidatesMin()

Description copied from interface: GeneralFeatureIntensity

(Optional) Returns a list of candidate for local minimums.

Returns:

List of potential features. If not supported then null is returned.

getCandidatesMax

@Nullable
public @Nullable ListIntPoint2D getCandidatesMax()

Description copied from interface: GeneralFeatureIntensity

(Optional) Returns a list of candidate for local maximums.

Returns:

List of potential features. If not supported then null is returned.

getRequiresGradient

public boolean getRequiresGradient()

Description copied from interface: GeneralFeatureIntensity

If the image gradient is required for calculations.

Returns:

true if the image gradient is required.

getRequiresHessian

public boolean getRequiresHessian()

Description copied from interface: GeneralFeatureIntensity

Is the image's second derivative required?

Returns:

is the hessian required.

hasCandidates

public boolean hasCandidates()

Description copied from interface: GeneralFeatureIntensity

If true there is a list of candidate corners for minimums and/or maximums.

getIgnoreBorder

public int getIgnoreBorder()

There is no ignore border, unless the derivative that it is computed from has an ignore border.

Returns:

Size of unprocessed border around the image.

localMinimums

public boolean localMinimums()

Description copied from interface: GeneralFeatureIntensity

Indicates if local minimums are features or not.

Returns:

true for local minimum features.

localMaximums

public boolean localMaximums()

Description copied from interface: GeneralFeatureIntensity

Indicates if local maximums are features or not.

Returns:

true for local maximum features.
