Class FaceDetector

src/com/cloudream/ishow/algorithm/FaceDetector.java:52–1152

Accidently found that Android itself has a FaceDetector class #android.media.FaceDetector but it only gives found faces without feature points. It use FFTEm library, I will dig it later. FFT is Fast Fourier Transform, EM may refer to "expectation-maximization". http://stackoverflow.com/questions/335
