A Novel Short-Time Fourier Transform-Based Fall Detection Algorithm Using 3-Axis Accelerations

The short-time Fourier transform- (STFT-) based algorithm was suggested to distinguish falls from various activities of daily living (ADLs). Forty male subjects volunteered in the experiments including three types of falls and four types of ADLs. An inertia sensor unit attached to the middle of two...
