Hey guys,
I have a problem here, I used the facedetector tutorial provided by
Google and got it working. Once I did this I tried creating a menu
that allows a user to take a picture and then once taken, choose an
image to be recognized. The problem arises with the face detection. I
can display the image from the gallery but when I try and recognize a
face within the image it doesn't work.
The code below shows my code;
[code]
public void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
canvas.drawBitmap(bitmap, 0, 0, null);
Paint myPaint = new Paint();
myPaint.setColor(Color.GREEN);
myPaint.setStyle(Paint.Style.STROKE);
myPaint.setStrokeWidth(3);
for(int i=0; i < numberOfFaceDetected; i++)
{
Face face = myFace[i];
PointF myMidPoint = new PointF();
face.getMidPoint(myMidPoint);
myEyesDistance = face.eyesDistance();
canvas.drawRect(
(int)(myMidPoint.x - myEyesDistance),
(int)(myMidPoint.y - myEyesDistance),
(int)(myMidPoint.x + myEyesDistance),
(int)(myMidPoint.y + myEyesDistance),
myPaint);
}
}
@Override
public void onActivityResult(int requestCode, int resultCode,
Intent
data) {
if (requestCode == ACTIVITY_SELECT_IMAGE && resultCode
== RESULT_OK)
{
try {
Uri currImageURI = data.getData();
String[] proj = { Images.Media.DATA,
Images.Media.ORIENTATION };
Cursor cursor =
managedQuery(currImageURI, proj, null, null,null);
int columnIndex =
cursor.getColumnIndex(proj[0]);
cursor.moveToFirst();
mCurrentImagePath =
cursor.getString(columnIndex);
BitmapFactory.Options
BitmapFactoryOptionsbfo = new
BitmapFactory.Options();
BitmapFactoryOptionsbfo.inPreferredConfig =
Bitmap.Config.RGB_565;
Bitmap bitmap =
BitmapFactory.decodeFile(mCurrentImagePath);
int width = bitmap.getWidth();
int height = bitmap.getHeight();
myFace = new
FaceDetector.Face[numberOfFace];
myFaceDetect = new FaceDetector(width,
height, numberOfFace);
numberOfFaceDetected =
myFaceDetect.findFaces(bitmap, myFace);
mImageView.setImageBitmap(bitmap);
catch (Exception e) {
}
}
[/code]
