Field Detail

ID_UNSUPPORTED

public static final int ID_UNSUPPORTED

Deprecated. 

The ID is -1 when the optional set of fields is unsupported.

getId()

SCORE_MIN

public static final int SCORE_MIN

Deprecated. 

The minimum possible value for the confidence level.

See Also:

getScore()

SCORE_MAX

public static final int SCORE_MAX

Deprecated. 

The maximum possible value for the confidence level.

See Also:

getScore()

Constructor Detail

Face

public Face()

Deprecated. 

Method Detail

getBounds

public abstract Rect getBounds()

Deprecated. 

Bounds of the face.

A rectangle relative to the sensor's CameraCharacteristics.SENSOR_INFO_ACTIVE_ARRAY_SIZE, with (0,0) representing the top-left corner of the active array rectangle.

This method will never return null. There are no other constraints.

Returns:

The bounds of the face.

getScore

public abstract int getScore()

Deprecated. 

The confidence level for the detection of the face.

The range is 1 to 100. 100 is the highest confidence.

Depending on the device, even very low-confidence faces may be listed, so applications should filter out faces with low confidence, depending on the use case. For a typical point-and-shoot camera application that wishes to display rectangles around detected faces, filtering out faces with confidence less than half of 100 is recommended.

Returns:

The confidence level.

See Also:

SCORE_MAX, SCORE_MIN

getId

public abstract int getId()

Deprecated. 

An unique id per face while the face is visible to the tracker.

If the face leaves the field-of-view and comes back, it will get a new id.

This is an optional field, may not be supported on all devices. If the id is -1 then the leftEyePosition, rightEyePosition, and mouthPositions are guaranteed to be null. Otherwise, each of leftEyePosition, rightEyePosition, and mouthPosition may be independently null or not-null. When devices report the value of key CaptureResult.STATISTICS_FACE_DETECT_MODE as CameraMetadata.STATISTICS_FACE_DETECT_MODE_SIMPLE in CaptureResult, the face id of each face is expected to be -1.

This value will either be -1 or otherwise greater than 0.

Returns:

The unique id.

ID_UNSUPPORTED

getLeftEyePosition

public abstract Point getLeftEyePosition()

Deprecated. 

The coordinates of the center of the left eye.

The coordinates are in the same space as the ones for getBounds(). This is an optional field, may not be supported on all devices. If not supported, the value will always be set to null. This value will always be null only if getId() returns -1.

Returns:

The left eye position, or null if unknown.

getRightEyePosition

public abstract Point getRightEyePosition()

Deprecated. 

The coordinates of the center of the right eye.

The coordinates are in the same space as the ones for getBounds(). This is an optional field, may not be supported on all devices. If not supported, the value will always be set to null. This value will always be null only if getId() returns -1.

Returns:

The right eye position, or null if unknown.

getMouthPosition

public abstract Point getMouthPosition()

Deprecated. 

The coordinates of the center of the mouth.

The coordinates are in the same space as the ones for getBounds(). This is an optional field, may not be supported on all devices. If not supported, the value will always be set to null. This value will always be null only if getId() returns -1.

Returns:

The mouth position, or null if unknown.

toString

public abstract String toString()

Deprecated. 

Represent the Face as a string for debugging purposes.

Overrides:
