Abstract |
Automated gait feature analysis is a precise and objective way to measure gait. Amplitude Spectrum (AS) is created to extract gait length signal of three types of walking speed (slow, normal and fast speeds). This spectrum shows the ability for extracting seven gait features that are reduced by using Principal Component Analysis (PCA) technique. In this paper, the Convolutional Encoder (CE) technique is used to classify the extracted gait features according to the kind of walk speed. In this classification technique, the Hamming Distance is used to calculate the optimum metric path among the classes. The obtained results show that 97.1% of the considered parameters are appropriate for classifying between three kinds of walk speeds. Keywords- Amplitude spectrum, convolutional encoder, Hamming distance, principle component analysis. | |||||||||
