tensorflow android demo : front camera and landscape question












0















I want to detect human face by front camera.



I have changed my camera to front, and changed location like this, and 288 is model's image's input size.
in DetectorActivity.java in function processImage



location.left = 288f - result.getLocation().left;
location.right = 288f - result.getLocation().right;


in LegacyCameraConnectionFragment.java in surfaceTextureListener



camera.addCallbackBuffer(new byte[ImageUtils.getYUVByteSize( s.width,s.height)]);
textureView.setAspectRatio(s.width,s.height);


in LegacyCameraConnectionFragment.java ORIENTATIONS



static {
ORIENTATIONS.append(Surface.ROTATION_0, 0);
ORIENTATIONS.append(Surface.ROTATION_90, 90);
ORIENTATIONS.append(Surface.ROTATION_180, 180);
ORIENTATIONS.append(Surface.ROTATION_270, 270);}


now my code can detect human correctly, but the bounding box tracks in opposite direction(left- >right. right->left ). Maybe I miss to edit somewhere's location ?



Another question is , sometimes when target moves, a new bounding box occurs, but the old one is still there ,too. However,if preview changes a lot (like target leaves quickly, or new target in), the old box will disappear .
If any one have any idea I will appreciate.
I recorded the detection scene and put it below .
