AE: Reviewers #1 & #2 are contented with this revised version, while Reviewer #3 remains a few concerns, especially in the technical aspect. So, we would ask the authors to do a further revision to cater for the requirements of all the reviewers.

The authors resubmitted this paper without a response letter. After carefully checking the content, it seems that the authors have addressed all of my concerns. Therefore, I recommend to accept this paper.

Comments to the Author
In this paper, the authors proposed an effective method for detecting double JPEG compression for the color image by using the conversion error, rounding error, and truncation error on the pixel in the spherical coordinate system. It is interesting. I have a few questions.

1.        The most serious part is the organization of the paper, especially for the introduction section. It is highly suggested that the “State of the Art” should be split as one individual section, named as related work. Thus the introduction part can be more compact and easy for the reviewers to catch the point.
2.        The authors proposed that they fully use three channels for map to spherical coordinates. These seems to be one straightforward extension. I am wondering the effectiveness and novelties.
3.        The paper needs to be more carefully revised and reorganized. Some parts seem to be very redundant. For example, the color space conversion in Eq. (1) and (2) are the common knowledge, which should not be included in the paper.
4.        The section II and the first part of section III seem to discuss the fore types of errors in color image JPEG compression, which seem to be overlappling. The authors are suggested to reorganize the paper to make it clearer. 返回小木虫查看更多
