Novel Image State Ensemble Decomposition Method for M87 Imaging
Round 1
Reviewer 1 Report
This is absolutely very well written paper of the review character, treating the problem of multiresolution of astronomical images from the perspective of original approach. The paper provides very strong mathematical background, very good graphics, and adequate list of references, importantly, not avoiding discussion of practical issues related to numerical efforts. Graphical data for the implementation were taken from the top-level SST telescope. In my opinion the actual text should be published as soon as possible, and in this way will be very supportive for scientist working with image processing issues, not only in astronomy.

Reviewer 2 Report
This paper studies a method for decomposition of images, which is called image state ensemble decomposition, for standard RGB (colour) images. The method is applied on TIFF images acquired from Space Telescopes. The English language level of the manuscript is good but has some minor issues and needs a final proof-dreading before publication.
This article is acceptable for publication, however there are some minor modifications that should be addressed as follows:
Minor comments:
The introduction does not provide enough literature review over previous related work,
In Line 30, it is claimed that “Our approach is novel”. But it is not supported at all. The authors need to explain clearly why their method is novel by providing a comprehensive literature review of the previous related work, state the gap in the literature, and clearly explain how their work is going to fill that gap.
122-128: The example of coffee and thermos bottle does not sound scientific and also it is difficult to understand its connection to the concepts of the paper.
201: “full reference and no-reference quality metrics were used”. Please define and explain these metrics.
216: “The following pseudocode” should be cross-referenced and the algorithm in Line 218 should be provided as a table (it also needs a caption).
218: Please provide more details of the algorithm. The sentences are too generic.
Minor text related errors:
Lines 53, 285, 334: The link “https://sites.google.com/view/isedisee/home-m87.” Should not be written in line with text. They should be provided in the bibliography and only be cited in the text with numbers in square bracket.
55: A reference should be provided for the sentence.
177, 181, 188, 190: The headlines should not be ended with dot (.), please delete them. Aslo, except 177 the other headlines are not numbered. Please make it consistent.
213: “results and discussion sections” results and discussion should be capitalized (Results and Discussion) to indicate that they are cross-referencing.
231, 235, 246, 247: Square brackets should only be used for citing the bibliography. Please use normal parenthesis “()” here such as “original image (Figure 2a)”
278: “in, the original image” remove comma “,”
