N-term nonlinear approximation of the layer-based representation in comparison to a standard multi-dimensional DWT. The percentage of retained coefficients is evaluated as $\frac{100N_r}{N_d}$, where N _r is the total number of retained coefficients and N _d is the total number of pixels in the dataset.
