Abstract
The system proposes an economical kinematic gait analysis by using image processing in MATLAB. Firstly, few second walking gait videos are taken by placing markers on the joints of the person. These markers are detected by using intensity thresholding technique in image processing. Detected markers are used to generate the stick figure. From the stick figure kinematic angles of knee and ankle joint are measured. This system is applied on five normal adults (average 24 year age). The accuracy of the proposed system is checked by comparing these kinematic data with clinical gait analysis normative database. The temporal parameters of kinematic gait analysis are also studied by observation.
