Design of Robust Sensing Matrix for UAV Images Encryption and Compression
Round 1
Reviewer 1 Report
I appreciate the authors' contribution to the novel formulation and algorithm. However, I don't understand the motivation of this research because I don't see the meaning of ``groups of sparse representation." Could the authors clarify the meaning of ``groups" in this context? Also, could the authors explain how the grouping improves the accuracy in the UAV123 data analysis?
I can't see the superiority of the authors' proposed method over the existing techniques from Fig.3 - 5. The authors should describe some considerations for the results from Fig.3 - 5.
I found several spelling mistakes throughout the paper. It is better to use grammar check software.

Reviewer 2 Report
1. It is more proper to consider that the paper proposed an image recovery framework based on compressive sensing and used some UAV image datasets in numerical experiments. Other than that, I don’t see a close relationship between the proposed algorithm and its application to UAV images. For example, an online learning framework is more related to UAV images.
2. Since f is a least-squares problem w.r.t. Phi^T Phi in (19), the related lengthy derivations could be much more concise.
Some typos:
1. the authors seem to use \xi and \eta interchangeably
2. "the critical issue of our research." -> "the main focus of our research"
3. "by employed the CS technique" -> "by employing the CS technique"
4. "low dimensional measurement" -> "low dimensional measurements"
5. "constraint of sparse" -> "constraint of sparseness"
6. Constraint on Gt is missing, resulting to trivial solutions: Gt=0, Phi=0
7. "focused on how does" -> "focused on how the ..."
8. G in (7) is not defined
9. "controlled being projected" -> "controlled when being projected"
10. "more accuracy" -> "high accuracy"
11. =min -> = arg min
12. authors proposes -> authors propose
13. "which extracting 15 patches" -> "which extract 15 patches"
14. (33) || ||_2^2 should be || ||_F^2
15. with different dimension -> with different dimensions
16. are also list -> are also listed
17. are match with -> are matched with
