started working on k mean clustering for seperative stuck together marbles
detection seems to be working relatively well, only one or two errors.
created a gitignore file
 added a circle function
Started implementing chattycharyya distance comparison function
finally figured out Bhattycharyya distance, started implementing
added marble detected performance(ratio). I am not sure about what does the state(1).x and state(1).y returns. I just used them as the detected marble centroid position. I am not sure how it works, please correct it.
working bhattacharyya distance
Merge branch 'master' of github.com:nihakue/av1
removed borrowed bhat distance and cleaned up unused functions
created the state vector array, saved it to all_states.mat, and cleaned up code in marble_detection
merged dong with updated master
Merge branch 'dong' of github.com:nihakue/av1 into dong
