Reviewer 2 Report
Would be helpful to compare the running time if you could write what hardware and what programming language were used for the simulations.
line 369: delete "become"
Author Response
The authors will give greatly gratitude to your kind concern and review comments. The hardware is coded by C , and we test our algorithm in Matllab. We will highlight these information in this paper.
we delete "become" in line 369, sorry for this editing mistake.
Round 2
Reviewer 1 Report
- The choice of non-unified metric for the three algorithms is still unjustified. While the algorithms used different approaches/ methodologies they should comply with a similar metric for performance evaluation. Handling the same research problem inherently requires a unified metric for performance.
- Authors are advised to present the algorithm complexity in big-O notation.
- The quality of the images still needs attention.
Author Response
Much more thanks for your kindly further comments and suggestions.
(1)We might firstly misunderstanding the word of "metric", using different statistic parameters to try to evaluate the performance of 3 algorithms, actually , prior parameters finally work to build the similarity index which is the correlation coefficient , so this value should be reasonable to act as a uniform performance evaluation metric. We highlight this in the revised paper to make it much more clear when comparing the performance of different algorithms.
(2) We add time complexity analysis in subsection 3.4 , before that , we only give a description of experienced analysis from algorithm flow chart, this time , we calculate the O() for the three algorithms. Thanks for your kind suggestion, we think complexity analysis should be more quantitative and scientific with these extra content.
(3) we check all figs again , and replot fig10.
