Round 1

Reviewer 1 Report

This manuscript provides the Growing Neural Gas with Different Topologies (GNG-DT) for perceiving the 3D environmental space from the unknown 3D point cloud data.
This manuscript has a good overall composition and is well written. However, there is a lack of comparative analysis of the performance of various related techniques and proposed techniques mentioned in the introduction. Additional analysis is needed in the experimental part of the manuscript.

Reviewer 2 Report

This paper proposed the Growing Neural Gas with Different Topologies (GNG-DT) for perceiving the 3D environmental space from the unknown 3D point cloud data. GNG-DT applied to only the static data measured by the RGB-D camera.

  • The results and conclusion are missing in the abstract. The introduction section and background should be summarized.
  • For an easier read of the manuscript, the authors should respect different sections of the journal guideline  (Introduction, Material and Methods, Conclusion, Discussion, and Conclusion).
  • Differents studies are conducted about 3D space perception, what is the novelty of your study?
  • Weak literature research ( only 35 references)
  • The whole of references (35) is used only for the Introduction and Background sections.
  • There is no Discussion section? The results were not discussed in the manuscript.
  • What is the implication of this study?

 

Specific comment:

  • For all tables: PLZ add the abbreviation and their meaning below each corresponding table. 
  • Figure 2 should be clarified.
  • Some equation explications were missed.

Round 2

Reviewer 1 Report

The revised manuscript is written by reflecting the comments of the reviewers well.

Reviewer 2 Report

The authors took into account all the suggested corrections. Thus, their manuscript is much more comprehensive and accurate.  I consider that the paper is worthwhile to be published in this form.
