Hi,

Im building an Android app, using opencv 3.4.5 version.(with Android studio ).

I have two questions:

  1. In openCV 3.4.5, Android package, in the file "MatOfDMatch.java", the following comment apper: "//FIXME: do we need release() here?". Do we need a release in the constructor ?.
  2. After running the line: *orb.detectAndCompute(img1re, new Mat(), kp1, des1);

how can I know how many features found ? numerically, without the draw function ?

Ok, Thanks. What about the first question ?

I also searched for the github of the android package, but didnt find it. (The one we can download from opencv site).

that's an implementation detail (code there is also autogenerated (as well as the comment !))

none of your concern, i'd say.
