The STFT images of IMU and KR right-knee Y-direction acceleration data of a subject. The horizontal coordinate is time, the left vertical axis is frequency value, and the right vertical axis is energy intensity value. It indicates the energy magnitude of the signal at a specific time and frequency. The colors in the image represent energy intensity. The darker the color, the higher the frequency of exercise and the greater the energy intensity. From (a) and (b), both Phase 2 color are darker than those in Phase 1
