TABLE III:

Average SSIM and RMSE values with standard deviation of the rigid motion compensated reconstructions from noisy signals compared to the motion-free reconstruction over all scans. The noise factor is 10−fa for the simulated accelerometer resp. 10−fg for the gyroscope. All measures were computed on the whole reconstructed part of the leg, and on the shank resp. thigh only.
