Figure 8

Simulation results for dynamic protocol. Performance comparisons of the proposed method of S-EMG data compression in the studies reported in scientific literature. In this figure, results are shown which were obtained using the decreasing square-root (DSR) and Rotated Hyperbolic Tangent Bit Allocation Shape (RHT) spectral shape approximation. Also, this figure shows performance results found in Norris et al.[7]–based on the EZW (embedded zero-tree wavelets) scheme, Berger et al.[13]–based Wavelet Transform, neural network bit allocation procedure and Huffman entropy coding, and Costa et al.[20]–based on a two-dimensional technique for S-EMG compression. It is also important to notice that [13] and [20] used the same dynamic S-EMG signal data bank used in this work.
