In order to achieve a comprehensive analysis of EOMP method, Gabor dictionary and Ilfm dictionary are used to decompose and reconstruct the same simulated signal in (15).
(1) Gabor dictionary and Ilfm dictionary are used to decompose and reconstruct the simulated signal of (15) in the OMP algorithm.
However, Figures 2(a), 2(b), and 2(c) show that the method that uses Ilfm dictionary in the combinations of the IQGA and the OMP algorithm has the lowest residual, the best comparability of reconstruction, and the minimal error of reconstruction.
The main research work can be summarized as the following aspects: (1) it is novel that the EOMP method uses Ilfm dictionary in the selection of dictionary and the performance of this method is better than that of the common OMP method using Gabor dictionary in terms of accuracy and computing efficiency.
This software users award is particularly significant as the winner is chosen by ILFM members rating their software for usability, functionality and quality of support.
Mr Carmody said "It's so exciting to have confirmation from ILFM that we are succeeding in delivering great service to all our clients.
