Systems detected FOG and other gait postures and showed time-frequency range by examining differentiated decomposed signals by DWT. Energy distribution and PSD graph proved the accuracy of the system. Validation is done by the LOSO method which shows 90% accuracy for the proposed method.
Observations of the clinical trials validate the proposed technique. In comparison to the previous techniques reported in literature, it is seen that the proposed method shows improvement in time and frequency resolution as well as processing time.
系统检测到冻结步态及其他步态姿势,并通过离散小波变换(DWT)检查微分分解信号来显示时频范围。能量分布和功率谱密度(PSD)图证明了系统的准确性。通过留一法(LOSO)进行验证,结果表明所提出的方法准确率达90%。
临床试验观察验证了所提出的技术。与文献中报道的先前技术相比,可以看出所提出的方法在时间和频率分辨率以及处理时间方面都有改进。
