Class FaceScanner.InputImageProcessor

java.lang.Object

com.libremobileos.yifan.face.FaceScanner.InputImageProcessor

Enclosing class:

FaceScanner

public static class FaceScanner.InputImageProcessor
extends Object

Processes Bitmaps to compatible format. This class supports 2 modes of operation:
1. Preprocess perfectly cropped Bitmap to AI-compatible format, using the static method process(Bitmap, int)
2. Crop one large Bitmap to multiple FaceScanner.InputImages using bounds inside RectF objects, with InputImageProcessor(Bitmap, int) and process(RectF). This allows processing multiple faces on one Bitmap, for usage with FaceDetector and similar classes.

Constructor Summary

Constructors

Constructor	Description
InputImageProcessor(Bitmap rawImage, int sensorOrientation)	If the class gets instantiated, we enter a special mode of operation for detecting multiple faces on one large Bitmap.

Method Summary

Modifier and Type	Method	Description
FaceScanner.InputImage	process(Bitmap input)	In normal mode of operation, we take a perfectly cropped Bitmap containing one face and process it.
static FaceScanner.InputImage	process(Bitmap input, int sensorOrientation)	In normal mode of operation, we take a perfectly cropped Bitmap containing one face and process it.
FaceScanner.InputImage	process(RectF inputBB)	In special mode of operation, we crop the image to detect multiple faces on one large Bitmap (in multiple passes).

Constructor Detail

InputImageProcessor

public InputImageProcessor(Bitmap rawImage,
                           int sensorOrientation)

If the class gets instantiated, we enter a special mode of operation for detecting multiple faces on one large Bitmap.

Parameters:

rawImage - The image with all faces to be detected

sensorOrientation - rotation if the image should be rotated, or 0.

Method Detail

process

public static FaceScanner.InputImage process(Bitmap input,
                                             int sensorOrientation)

In normal mode of operation, we take a perfectly cropped Bitmap containing one face and process it.

Parameters:

input - Bitmap to process.

sensorOrientation - rotation if the image should be rotated, or 0.

Returns:

Converted FaceScanner.InputImage

process

public FaceScanner.InputImage process(Bitmap input)

In normal mode of operation, we take a perfectly cropped Bitmap containing one face and process it. This utility method uses sensorOrientation that was passed in the constructor and calls process(Bitmap, int)

Parameters:

input - Bitmap to process.

Returns:

Converted FaceScanner.InputImage

process(Bitmap, int)

process

public FaceScanner.InputImage process(RectF inputBB)

In special mode of operation, we crop the image to detect multiple faces on one large Bitmap (in multiple passes).

Parameters:

inputBB - RectF containing location of face cropped out next

Returns:

Converted FaceScanner.InputImage
