Class ScalingAligner<T extends DetectedFace>

java.lang.Object

org.openimaj.image.processing.face.alignment.ScalingAligner<T>

Type Parameters:

T - Type of DetectedFace.

All Implemented Interfaces:

FaceAligner<T>, ReadableBinary, ReadWriteableBinary, WriteableBinary

public class ScalingAligner<T extends DetectedFace>
extends Object
implements FaceAligner<T>

A FaceAligner that just scales the face patch held with the DetectedFace to a predefined size. Useful if your faces are already aligned, but have different sizes.

ScalingAligner

public ScalingAligner(int width,
                      int height)

Construct the aligner with the given target size

Parameters:

width - width of scaled faces

height - height of scaled faces

Method Detail

align

public FImage align(DetectedFace face)

Description copied from interface: FaceAligner

For the provided face detection, return an aligned version of the face.

Specified by:

align in interface FaceAligner<T extends DetectedFace>

Parameters:

face - the face to align

Returns:

aligned face

getMask

public FImage getMask()

Description copied from interface: FaceAligner

Return a mask image for aligned faces. 0 pixels mark background pixels that should be ignored in further processing of aligned faces produced by this aligner.

Specified by:

getMask in interface FaceAligner<T extends DetectedFace>

Returns:

a mask image, or null if masking isn't required

readBinary

public void readBinary(DataInput in)
                throws IOException

Description copied from interface: ReadableBinary

Read internal state from in.

Specified by:

readBinary in interface ReadableBinary

Parameters:

in - source to read from.

Throws:

IOException - an error reading input

binaryHeader

public byte[] binaryHeader()

Description copied from interface: ReadableBinary

Header for binary input. Will be automatically read by IOUtils when using readBinary().

Specified by:

binaryHeader in interface ReadableBinary

Specified by:

binaryHeader in interface WriteableBinary

Returns:

header

writeBinary

public void writeBinary(DataOutput out)
                 throws IOException

Description copied from interface: WriteableBinary

Write the content of this as binary to out.

Specified by:

writeBinary in interface WriteableBinary

Parameters:

out - sink to write to

Throws:

IOException - an error writing to out
