Yoga Tutor is a software prototype developed by Senior E&TC students Gandhar Tannu, Sahil Shingvi and Yash Oswal. This project uses Digital Image Processing techniques and Computer Vision algorithm to detect positional errors in Yoga postures. This project was developed in 6 months by the students. For their efforts, students were rewarded with average score of 142 marks out of maximum 150 (94%).

2. Vision behind yoga tutor
IMAGE PROCESSING
YOGA- THE BEST MEDICINE
A NEW AND INNOVATIVE IDEA
“IT’S A FANTASTIC INITIATIVE!
I WOULD LIKE TO EXTEND MY
FULL SUPPORT TO THIS VENTURE!”
PADEKAR GURUJI

3. Why
yoga?
UNIVERSAL MEDICINE
BEST EXERCISE FOR ALL AGES
NO EQUIPMENT NEEDED
LONG LASTING EFFECTS
YEAR-AROUND PRACTICE

4. Benefits of yoga
STRESS & PAIN RELIEF
FLEXIBILITY
INCREASED STRENGTH
WEIGHT MANAGEMENT
IMPROVED CIRCULATION
INNER PEACE

5. Challenges for practicing yoga
DIFFICULT ART TO LEARN
LESS QUALIFIED PRACTITIONERS AVAILABLE
PHYSICALLY, MENTALLY
AND EMOTIONALLY CHALLENGING
INTIMIDATING FOR BEGINNERS
INCORRECT PRACTICES
MAY LEAD TO INJURIES

6. NEED
FOR
YOGA TUTOR
ONLY LONG TERM SOLUTION
FOR CURRENT DAY PROBLEMS
YOGA PRACTICE BEING INCREASED
EVERYDAY
YOGA HAS TO BE PRACTICED PERFECTLY
NO SELF-HELP YOGA SYSTEM DEVELOPED
URGING NEED OF AUTOMATED SELF-HELP
YOGA CORRECTION SYSTEM
THIS SYSTEM PROVIDED BY YOGA TUTOR

7. MARKET SURVEY
IN AMERICA 15 – 20 MILLION PEOPLE PRACTICE YOGA
AND INDIA IT IS LOT MORE
AMERICANS SPEND $5.7 BILLION A YEAR ON YOGA
(CD’S, DVD’S, etc.)
YOGA CAMPS AND WORKSHOPS ORGANISED EVERYWHERE
(RAMAMANI IYENGAR MEMORIAL YOGA INSTITUTEMOST REPUTED)
CD’S, DVD’S AVAILAIBLE IN MARKET FROM VARIOUS AUTHORS
HIS HIGHNESS, PADEKAR GURUJI, CONDUCTS WORSHOPS AND
SEMINARS

8. CONCLUSIONS
FROM
MARKET SURVEY
YOGA TUTOR NOT IMPLEMENTED
COMMERCIALLY TILL DATE
THERE IS URGENT NEED OF YOGA TUTOR
IN MARKET

15. SURF ALGORITHM
(SPEEDED UP ROBUST FEATURES)
A ROBUST IMAGE DETECTOR & DESCRIPTOR ALGORITHM
FIRST PRESENTED BY HERBERT BAY ET AL. IN 2006
USED IN COMPUTER VISION TASKS LIKE
OBJECT RECOGNITION OR 3D RECONSTRUCTION
PARTLY INSPIRED BY THE SIFT DESCRIPTOR
THE STANDARD VERSION OF SURF IS
SEVERAL TIMES FASTER THAN SIFT
MORE ROBUST AGAINST DIFFERENT
IMAGE TRANSFORMATIONS THAN SIFT.
