Ball Tracking, Event Detection, Video Summarization of Football
Vishwa Mangal Mentor: Dr. Aditya Nigam
• Ball Tracking done using STRUCT (structured output for kernel Tracking).
• Ground truth for the first few frames are given and then it tracks the ball in subsequent frames.
• Stores the features from the ground truth and searches in radius of “R” which best match the feature.
• Audio summarization using PRAAT language.
• High Pitch implies the important moment of match.
• The threshold was found at 60% of the mean pitch.
Raw Data collection of Forehand,
Backhand, and Service

YOLO in each frame.

Working Of YOLO YOU ONLY LOOK ONCE
Data Specification
• Australian open final 2017.
• video to frame at 15FPS.
• Manually classified frames into forehand, backhand, service.
• 30 instances each of forehand, backhand, and service.
Performance
• Train/Test split at 50/10 for 2 class and 80/10 for three class.
• On testing with two class i.e forehand and backhand, we got the 100% accuracy.
• On testing with three class we got the accuracy of 70%.
Future Work
• Classify the s t r o k e s i n u n t r i m m e d videos using T - CNN.
100% accuracy with 2 class.
70% accuracy with 3 class .
