Yoga tutor visualization and analysis using SURF algorithm

Yoga is an ancient Indian art which helps to distress and purge the mind, body and soul. It is known to be a complete cure for various illnesses without the use of medicines. The paper aims to describe a project which is used to help naïve users to perform this ancient Indian art correctly in order to maximize the benefits. It makes use of the SURF algorithm to detect the `asana' that the user/practitioner is performing and compares it with a video of the same `asana' performed by an expert. Thus, it helps to detect and eventually correct errors induced in practicing the art using only a webcam and an expert video as aides for the user.
