RoiSeg: An Effective Moving Object Segmentation Approach Based on Region-of-Interest with Unsupervised Learning

Round 1

Reviewer 1 Report

The authors developed a method to segment moving objects considering a region of interest in the central region of the frames and unsupervised learning. The proposed method can handle some problems found in the images and has a better performance than other segmentation algorithms do. There are, however, some issues to be improved in the manuscript.

1) When presenting and discussing the results, the authors should use the past verb tense. I suggest reviewing the writing to correct such an issue in the manuscript.

2) Referring to figures with just their numbers is unusual and leads to confusion. I recommend adding "Figure" or "Fig." before their numbering to improve the readability of the manuscript.

Response 1.2

Thanks for your reminding. We have added "Fig." in our revised manuscript.

Reviewer 2 Report

Authors proposed ROI-central-point generation and feature extraction, automatic training-sample generation, and classification. Literature review and background research is enough to understand fundamental research about related work. English grammar looks fine. Simulated results for classification is interesting. Therefore, the manuscript can be minor revision. However, authors need to revise the manuscript according to the comments as below. 

1. Figure 1 fonts are small to be seen.
2. Figure 2 label size need to be increased.
3. Figures 3, 4, and 5 had better combined to one Figure.
4. Figures 6 and 7 had better combined to one Figure.
5. Figures 9 and 10 labels are too small.
6. Tables 6,7, and 8 had better combined to one Table.
7. Authors need to have abbreviated journal names in the reference sections.
8. No data availability section, No funding, and No acknowledgement sections.
9. In the conclusion section, authors need to emphasize important data.
10. In Line 366, please change [41-48] for the references.
