Reviewer 2 Report

The article high-accuracy 3D contour measurement by using the quaternion wavelet transform image denoising technique presents an interesting image denoising algorithm based on the quaternion wavelet transform (QWT) to address sinusoidal fringe images under strong noise in structured light 3D profilometry.

The introduction is well-documented and the algorithm is correctly explained. However, the discussion is poorly and it is necessary to complement it. The authors have to explain the results more deeply in a scientific language.

 The article is not scientific research, it is more like a technical or analytical report. The authors must consider changing the kind of manuscript that is more adequate for publication.

Reviewer 3 Report

The article proposes an image denoising algorithm based on the quaternion wavelet 1 transform (QWT) to address sinusoidal fringe images under strong noise in structured light 3D 2profilometry.

Overall, the article is well organized and its presentation is good. However, some minor issues still need to be improved:

（1）The authors should summarize the main contributions of this paper in Section 1.

（2）The authors should draw a flow chart of the algorithm of this paper in Section 1.

(3)  In Section 3, the author may make necessary comparison between the proposed algorithm and some related denoising algorithms.

Reviewer 4 Report

The paper is a deserves publication after some improvements.

T This paper has a good structure and theory. The experimental results are also interesting and practical.

The following points should be improved before proceeding with the publications:

• It is recommended to design a table so that engineers can quickly understand the accuracy according to the experimental parameters

 

• The structure of this research is quite complicated .Please describe the proposed method using a Flowchart in which the steps are summarized. This can help the reproducibility of the method by users.

 

• Moreover, a general question arises. Generally speaking, deviation, disturbance value and amplification rate are associated with CCD measurement. It is a question worth discussing.
