There are two main research fields for gait analysis. Although the two area deal with human gait but they are distinct to each other in terms of thchniques and methods.Clinical gait analysis uses on collection of kinematic data in controlled environments using motion analysis systems and the data acquisttion system is integrated with motion anlaysis sytem..

    Motion analysis data provides large amounts of dta to describe motion such as walking speed and gait events, as well as joint angles,forces, and moments as function of the percent of the gait cycle. Using those data joint kinetics ,joint moments and joint powers have been used to for gait recognition lately .

    On the other hand Biometrix gait analysis concentrates on individual`s gait recognition in a variety of eifferent areas and scenarios .As a resultof this ,biometric gait analysis is based on visual data capture and analysis systems.

   Due to lavk of information like motion analysis system biometric gait recognition users computer vision method to describe motion that is exclusively being applied to identification tasks. However, gait can disclose more that identity.
