Abnormal Conductive State Identification of the Copper Rod in a Nickel Electrolysis Procedure Based on Infrared Image Features and Position Characteristics

Round 1

Reviewer 1 Report

In line 90, presumably it should be written “Fig. 2” instead of “Fig. 3”.

It seems that the international literature for this topic receives only slight consideration.

The figures are not always clear regarding the differences between the three conditions abnormal heating, open circuit and normal, especially for untrained eye. You have to search for the differences. It would be helpful to have an additional description in the text to indicate the distinguishing features, for example Fig. 4, Fig. 11 etc.

In line 90, presumably it should be written “Fig. 2” instead of “Fig. 3”.

It has been modified in the manuscript.

It seems that the international literature for this topic receives only slight consideration.

Two references had been added in the manuscript.

More explanatory statements have been added before Figure 4.

Fig. 11 shows the window positions determined by the position Characteristics, which will be used to cut the gray image. Binary images in Figure 11 does not express any difference in different conduction states.

Reviewer 2 Report

The article “Abnormal Conductive State Identification of Copper Rod in Nickel  Electrolysis Procedure Based on Infrared Image Features and Position Characteristics” is dealing with the IR image segmentation including position characterization, IR feature extraction and conductive faults identification (with SVM) for conductive state of copper rods identification.

My recommendation is major revision since there too many issues which require more information and explanation of statements, defining variables in equations and formulas and re-organisation of the manuscript. Additionally there are a lot of spelling and grammar errors. If authors are willing to make an in-depth revision, this manuscript can be reconsidered for publication.  

General comments and questions.

1. This manuscript has numerous spelling and grammar errors which should be corrected if the manuscript is re-submitted.
2. Parameters in formulas should be defined and/or explained when first introduced.
3. Acronyms and abbreviations should be explained when first introduced.
4. References 1-9 are not corrected and consistently introduced in the manuscript. E.g. Wang 1 should be [9]. Pei 7 should be [9].
5. A lot of careless assignments, statements and formulations are found in this manuscript which require in depth revision.
6. Caption of Figures should be revised.

Author Response

1. All abbreviations in this manuscript have been given the expression when first introduced.
2. The quotes in the manuscript have been modified according to the comments of reviewers.

Figure captions and expression errors pointed out by reviewers have been modified in the manuscript.

3. Line 62: “mastering the infrared image law of various equipment”: not clear to me. Please comment.

What we want to express here is that we have learned the relationship and law between equipment failure and temperature performance, and the sentence in manuscript has been modified.

4. Line 95:  “what is current converge”? Please comment.

The current of the cathode copper rod is transmitted to the cathode plate through 2-3 lugs, so the current density on the whole copper bar is unevenly distributed along the axial direction.

5. Line 102: what is the difference between conductive state and conductive condition? Both terminologies are used throughout the manuscript. Please comment.

That’s problem of negligence, “conductive condition” has been replaced by ”conductive state” in the manuscript.

6. Line 162: this line should be moved under line 163 (conditions for verticalMean) for a better understanding. Please comment.

For better understanding, the sentences order has been modified.

7. Line 225: M and N are not defined when introduced in equation (3). Please comment.

The definition of M and N has been added in the manuscript

8. Lines 239-240: This statement is in conflict with Figure 13. Please comment.

The description of sentence is correct, the annotations in the figure are wrong, which are not consistent with the horizontal labels, and Figure.13 has been modified.

9. Lines 250-252: m_pq and µ_pq are not defined eq. (7) and eq. (8) respectively. Please comment.

The definition of these to parameters has been added before eq. (7) and eq. (8).

10. Lines 247-260: Definition of Hu moments is incomprehensible: H1, H2, H3 or F1 F2 F3? Please comment.

Hu moments in equation (10) are the original form, but we only use the first three of seven, then parameters H_i are practical form, which have been used and accepted by researchers and engineers, the relationship between Hu moments and parameters H_i is described in the manuscript.

11. Lines 271: N1 and N2 are not defined when first introduced. Please comment.

N1 is the columns number of target copper rod area, N1 is the columns number of adjacent copper rod area. It has been modified in the manuscript.
