Is there a list of the algorithms within opencv and opencv_contrib ?

Hi, is there any documentation about a list of the algorithms within opencv and opencv_contrib (found here https://github.com/Itseez)? I tried to use SURF with native openCV from android sdk with jni files. SURF cannot be used here. I know that since openCV3 the nonfree stuff is no longer part of the sdk and can be found in opencv_contrib(along with other extra modules). It would be nice if I knew which algorithms I can or cannot use with the native openCV from the android sdk?! Thanks for any help. I appreciate it!
