android - Image processing, replace picture background or cut out picture background -

in android app, user take or take image of him / device , replace background 1 (for illustration awesome beach).

i'm looking library can cutting out original image background (the original background can color or maybe landscape). or maybe library can give me tools draw part of image maintain / remove.

if such library not exist, think "pixel replacement" method best way if original image has color background (for example, black pixel , alter them transparent pixel).

i have found this tutorial can see result not perfect. there way not check 1 color range of colors ? there way define programmatically range of colors check ?

thank in advance tips , links !
