Reviewer 2 Report
The current manuscript presents a methodology for tackling the motion-blur hysteresis phenomenon in visual tracking and displacement detection of moving objects. The method first decomposes the motion-blur operator (MBO) process to determine that the error of existing MBO generation methods comes from the approximation of boundary values, and proposes a more accurate generation method called accurate point spread function (APSF). The paper is well-written in general and can be accepted after a minor review as follows
1- It is difficult to grasp the main problem and the contribution of the paper from the abstract. Please improve the writing and the structure of the Abstract. The reviewer is suggesting following the IMRaD abstract style.
2- It is very useful to summarize the main research gaps and contributions using a bullet list before the last paragraph in the introduction section.
3-The authors have presented a lot of results. In order to better inform readers about major achievements, challenges, limitations, and recommendations, I either suggest adding a separate discussion section.
4- Please make sure that all the abbreviations are carefully defined before the first use of the manuscript.

Reviewer 3 Report
The article explores the constraints inherent in visual tracking and displacement detection due to motion blur, introducing an enhanced technique for generating motion-blur images that markedly diminish error compared to current methodologies. Additionally, the paper offers an in-depth analysis of the motion-blur hysteresis phenomenon (MBHP). It delineates three computational approaches for compensation value calculation aimed at mitigating the adverse effects of MBHP on video tracking, thereby achieving a noteworthy reduction in error. The overall idea is interesting; the main highlighted points follow such as:
1) The introductory section of the article is extensive, encompassing a range of domains such as image degradation, video object tracking, and image quality assessment. Despite its breadth, the introduction must offer a precise and succinct delineation of the article's core research issue: the identification, quantitative recurrence, and mitigation of the motion-blur hysteresis phenomenon in visual tracking displacement detection. The section would gain efficacy by presenting a more targeted and concentrated exposition of the research problem and the importance of its resolution. Section 1 of the article could benefit from a more concise presentation, potentially reducing its length by at least 50%.
2) The article presents several valuable contributions to visual tracking and displacement detection, most notably in addressing the limitations imposed by the motion-blur hysteresis phenomenon (MBHP). While the APSF method for generating motion-blur operators signifies an advancement in the field, offering a more authentic representation of motion, it could benefit from comparative analysis against other existing methods for a fuller contextual understanding. Creating motion-blur video datasets is a commendable effort, yet the paper could elaborate on how these datasets are superior to or different from existing databases. Furthermore, although the paper introduces three distinct methods for calculating compensation values to mitigate MBHP's effects, a deeper exploration into each method's relative advantages and drawbacks might offer a more nuanced perspective. Finally, the empirical verification of the proposed compensation values is crucial, but the study could enhance its rigor by detailing the experimental design and statistical robustness. Ultimately, the research does contribute substantively to enhancing the speed, accuracy, and reliability of visual tracking and displacement detection; however, the implications could be made more compelling through these suggested refinements.
3) Although comprehensive, Section 2 of the article leans toward verbosity by overly focusing on well-established equations and definitions, thereby underrepresenting a targeted discussion on the state of the art. The section must highlight the paper's novel contributions, including the APSF method for more accurate motion-blur operators and generating specialized video datasets for MBHP analysis. To improve clarity and relevance, the section would benefit from a comparative table that situates these innovative approaches within the context of recent advancements in the field, particularly those developed between 2021 and 2023. Such a table could elucidate the article's unique contributions while substantiating its contemporary relevance.
4) The methodology outlined in the paper possesses several commendable features, particularly the introduction of the APSF method for more accurate motion-blur operators and the multi-pronged approach for mitigating the motion-blur hysteresis phenomenon (MBHP) effects. However, a few areas could benefit from further refinement for an enhanced academic contribution. Firstly, while the APSF method claims to reduce error compared to existing methods, the paper would benefit from clearly defining the metrics and benchmarks against which this reduction is measured. Secondly, utilizing the optimized cepstrum-based sub-pixel estimation method (SPEPSF) for validation introduces another layer of complexity; the study could elucidate whether more straightforward validation approaches might yield similar insights, thereby easing replication efforts. Additionally, while creating specialized motion-blur video datasets is a significant step, a more precise explanation of their attributes and how they advance beyond existing databases would lend further credibility to the findings. Lastly, although three distinct methods for calculating compensation values are proposed, the paper would be strengthened by a comparative analysis that elucidates the conditions under which each method performs optimally. Such nuanced evaluation could offer more targeted guidelines for application and foster broader utility.
5) While the paper presents a series of methods and findings that, at first glance, appear to advance the field of visual tracking and displacement detection, some concerns may temper enthusiasm for these results. Firstly, the APSF method, despite reducing the mean square error (MSE) by more than 49.47%, raises the question of whether this level of improvement is sufficient to warrant the complexity of implementing a new technique. One must also consider how the results would generalize across different platforms or conditions. Secondly, the optimized cepstrum-based sub-pixel estimation method (SPEPSF) may closely resemble actual motion. However, whether the accuracy gained is practically significant or incremental is still being determined.
The creation of motion-blur video datasets also warrants scrutiny. These datasets are claimed to enable a quantitative analysis of MBHP, yet the paper needs to thoroughly validate whether the datasets are broadly representative of real-world conditions. Moreover, the proposed methods for calculating compensation values may have achieved a 96% reduction in error. However, such a dramatic reduction necessitates critically assessing the experimental design and the practicality of employing these methods at scale.
Lastly, the paper's recommendations for changing tracking strategies and employing motion trackers propose a shift in established methodologies. Such a radical change begs the question of its viability in current infrastructural setups and whether the marginal gains in accuracy justify the costs associated with these changes. While the paper's findings may look promising, caution is warranted in assessing their broader implications and potential for real-world application.
6) Addressing the following open issues is crucial for a comprehensive understanding and application of the research presented in the paper:
- The primary limitation in visual tracking and displacement detection of moving objects needs to be explicitly defined, along with an in-depth analysis of how motion blur exacerbates this limitation.
- A thorough elucidation is required on how the APSF method advances beyond existing techniques for generating motion-blur operators (MBOs), specifically focusing on its impact on accuracy metrics.
- The motion-blur hysteresis phenomenon (MBHP) concept requires a more detailed exposition, covering its root causes, influencing factors, and potential ramifications.
- An extensive list of potential compensation values designed to mitigate the impact of MBHP in video tracking should be provided. Further, empirical evidence supporting the effectiveness of these compensation values in reducing error rates must be highlighted.
- Finally, recommendations from the paper's findings should be oriented toward improving visual tracking and displacement detection in real-world scenarios where strong motion blur is prevalent.
Clarifying these points will significantly bolster the paper's contribution and practical applicability to the field.
7) The article makes significant strides in visual tracking and displacement detection, particularly in mitigating the Motion-Blur Hysteresis Phenomenon (MBHP). However, it could benefit from a more focused presentation of the research problem, rigorous comparisons with existing methods, and more robust empirical validation. Additionally, questions regarding the practical applicability and feasibility of implementing the new techniques in existing systems should be addressed to strengthen the study's impact. The paper's length could also be reduced to between 17 and 20 pages for a more concise presentation.
A final proofreading check is necessary to avoid typos and grammatical errors.
