Convert IplImage to byte array or IplImage to Bitmap in JavaCV - Android Java

Convert IplImage to byte array or IplImage to Bitmap in JavaCV - Android Java - Other colours include white/silver, light green and blue, the latter of which would be our pick. Both phones have dual rear cameras and apart from the separate lenses (which only slightly protrude from the back of the case) the layout is just like the iPhone's. phone with them just about, well we have collected a lot of data from the field directly and from many other blogs so very complete his discussion here about Convert IplImage to byte array or IplImage to Bitmap in JavaCV - Android Java, on this blog we also have to provide the latest automotive information from all the brands associated with the automobile. ok please continue reading:

Hi techies,

Now iam gonna share a wonderful and efficient way on "How to convert IplImage to byte array in JavaCV" with pure java code.

How to convert IplImage to Android Bitmap

public static Bitmap IplImageToBitmap(IplImage src) {
Bitmap bm=null;
   int width = src.width();
   int height = src.height();
// Unfortunately cvCvtColor will not let us convert in place, so we need to create a new IplImage with matching dimensions.
IplImage frame2 = IplImage.create(width, height, opencv_core.IPL_DEPTH_8U, 4);
opencv_imgproc.cvCvtColor(src, frame2, opencv_imgproc.CV_BGR2RGBA);
                   // Now we make an Android Bitmap with matching size ... Nb. at this point we functionally have 3 buffers == image size. Watch your memory usage!
bm = Bitmap.createBitmap(frame2.width(), frame2.height(), Bitmap.Config.ARGB_8888);
bm.copyPixelsFromBuffer(frame2.getByteBuffer());
//src.release();
frame2.release();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
return bm;
}

How to convert IplImage to byte[]

public static byte[] IplImageToByteArray(IplImage src) {
Bitmap bm=null;
    int width = src.width();
    int height = src.height();
 // Unfortunately cvCvtColor will not let us convert in place, so we need to create a new IplImage with matching dimensions.
  IplImage frame2 = IplImage.create(width, height, opencv_core.IPL_DEPTH_8U, 4);
  opencv_imgproc.cvCvtColor(src, frame2, opencv_imgproc.CV_BGR2RGBA);
                    // Now we make an Android Bitmap with matching size ... Nb. at this point we functionally have 3 buffers == image size. Watch your memory usage!
  bm = Bitmap.createBitmap(frame2.width(), frame2.height(), Bitmap.Config.ARGB_8888);
  bm.copyPixelsFromBuffer(frame2.getByteBuffer());
  //src.release();
  frame2.release();
  ByteArrayOutputStream stream = new ByteArrayOutputStream();
  bm.compress(Bitmap.CompressFormat.PNG, 100, stream);
  return stream.toByteArray();
}
