public final class SelfieSegmenter

  1. Object
  2. SelfieSegmenter

ImplementsAutoCloseable, VisionAnalyzer<SegmentationMask>

Separates a person from the background, for background replacement or blur.

SelfieSegmenter segmenter = new SelfieSegmenter();
EncodedImage photo = EncodedImage.create(jpegBytes);

segmenter.process(VisionImage.encoded(jpegBytes)).ready(mask -> {
    // Everything below 60% foreground confidence becomes transparent, so
    // whatever is painted behind this image shows through.
    Image person = mask.cutOut(photo, 0.6f);
    preview.setIcon(person);
    segmenter.close();
}).except(error -> {
    Log.e(error);
    segmenter.close();
});

The mask has the model’s own resolution rather than the frame’s; SegmentationMask.cutOut(com.codename1.ui.Image, float) and SegmentationMask.toMaskImage(int) rescale it for you.
