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.[]–based on the EZW (embedded zero-tree wavelets) scheme, Berger et al.[]–based Wavelet Transform, neural network bit allocation procedure and Huffman entropy coding, and Costa et al.[]–based on a two-dimensional technique for S-EMG compression. It is also important to notice that [] and [] used the same dynamic S-EMG signal data bank used in this work.

Simulation results for isometric protocol. Performance evaluation of the proposed method of S-EMG data compression: emphasized in this figure is the Decreasing Square-Root Bit Allocation Shape (DSR) and Rotated Hyperbolic Tangent Bit Allocation Shape (RHT) spectral shape approximation. Also shown in this illustrative scenery is a comparison of the performance evaluation with relevant works found in scientific literature: Norris et al.[]–based on EZW (embedded zero-tree wavelets) scheme, Berger et al.[]–based Wavelet Transform, neural network bit allocation procedure and Huffman entropy coding, Berger et al.–improved []–based Wavelet Transform, neural network bit allocation procedure and arithmetic entropy coding, Costa et al.[]–based on two-dimensional technique to S-EMG compression, and Filho et al.[]–based on recurrent patterns algorithm. It is important to notice that [-] and [] used the same signal data bank used in this work.
