I am assuming you want to crop the face different than the detection box and around the face landmarks? It really depends on how you want to crop.

In general, you have landmarks and their x,y coordinates in the frame. You need to find an x,y for the top left corner and an x,y for the bottom right corner (i.e. a new bounding box). You could find some center x,y of the face (like the nose) and -/+ a value from it (scaled based on a distance, like the distance between the eyes).

Look in OnImageListener.java, and do these operations near the for loop that draws the landmarks on the bitmap.
