iKarate: Karate Kata Aiding System

Abstract

Karate is a martial art that can be performed using hands and feet to deliver and block strikes. Karate Kata moves must be executed in a unique way, many moves are performed incorrectly during training. In this paper, we offer a system that Karate performers, coaches, judges and sporting clubs could use. The system aids the Karate performers by capturing their moves using Kinect v2 sensor, pre-processing these moves and then analyzing these moves using F-DTW. A report is displayed to the performers that is easily understandable, to learn how the mistakes were made, and how to fix it/learn from them. F-DTW was used for proving the concept, and an average accuracy of 93.65% was achieved. This Paper is mainly concerned about the first Karate Kata (Heian Shodan).
