  15. Markov Chain Weather Model

  16. Simple Markov Model of Weather

  17. Prediction Based on State Transition Probability • If we want to know probability of the sequence SUNNY SUNNYSUNNYSUNNYSUNNY • Take initial probablity of SUNNY day i.e. on a any given day probability that it will be SUNNY is 0.30 • And for use to get another SUNNY day after a SUNNY day is 0.42 • So, by using Markov Chain we can say prbability of getting 5 consecutive SUNNY day is

  18. Challenges Faced During OpenMP

  19. Summary • Canny and Markov Chain Model is a simple and efficient way to perform edge detection however canny performs poorly with images taken during laparoscopy (good to get started) • Future work • Contribute improvements to MIS learning methodology.
