                         1. Introduction
                         The outbreak of the novel coronavirus infection (COVID-19) has caused concern around the world as it
                         causes illness, including death, and continues to spread from person to person in many countries [1]
                         CoVs are a large family of viruses, including Middle East Respiratory Syndrome (MERS) CoV and Severe
                         Acute Respiratory Syndrome (SARS) CoV [2]. On February 11, 2020, the World Health Organization
                         (WHO) declared ’COVID-19’ as a disease [3], Artificial intelligence (AI) is gradually changing practical
                         medicine and recent advances in digitized data collection, making machine learning (ML), computing
                         infrastructure and AI applications expand into areas previously reserved for human experts [4]. There-
                         fore, the main objective of this research is to be able to analyze the use of recognition and detection
                         systems that allow the identification of control measures established for the mitigation of SARS-CoV-2
                         contagion using masks and distancing as the main strategy of the study through the review of articles
                         on image processing and computer vision, using algorithms for a clear understanding of the prediction
                         and use of these computer tools in support of science and its application. The challenges and limitations
                         encountered will allow us to propose opportunities for improvement and a clear focus on the main
                         findings found in the information reviewed.

A bibliographic search in English was carried out in the eight academic repositories between the years
2019 and 2022, considering precise exclusion criteria. The selection of the research articles was due
to the similar characteristics with our research, considering that the new methods identified require
greater computational power. This research carried out a search strategy using several keywords related
to the coronavirus and keywords related to the detection, diagnosis and classification of masks under
the concept of AI and ML. We use these query methods to improve the search and investigation of
distancing and mask applications for various AI and machine learning systems.

2.2. Inclusion criteria
    • Articles are journals or conferences in English.
    • The focus is on the development of various applications, systems, algorithms, methods and
      technologies in artificial intelligence and machine learning.
    • Development focused on the detection and classification of masks and social distancing.

2.3. Exclusion criteria
    • Articles minor to the year 2019.

2.4. Study Selection
The process begins with the elimination of duplicate articles, Unique articles were screened by title
and abstract to verify their compliance with our inclusion and exclusion criteria. The relevant articles
have been carefully read. The process of collecting, extracting research data, and developing a review
document.

2.5. Data extraction and classification
Given the multidisciplinary topic of this systematic review, data extraction and classification were
performed for selected studies, including CoV data using AI applications, especially ML techniques,
to assess the effectiveness of viruses in detection, diagnosis, prevention and classification. Enhanced
data factors were extracted from the academic literature, including author nationality, publication
date, number of articles per year, and number of articles in the database. To provide a comprehensive
understanding of CoV, this study The discussed CoV and the growing scale of the global pandemic in
the context of artificial intelligence are analyzed using various ML and data mining algorithms, such as
classification, regression, and prediction. For each study, the document distinguishes the name of the
significant characteristics, the evaluation methods used and the exact status of each method. From the
analyzed literature, brief motivations, challenges, limitations and recommendations have been extracted
to address the serious health problems associated with CoV.
2.6. Results
The results of the search query performed in this study are shown in Figure 1. During data collection,
four queries were performed to cover all databases and search mechanisms. The first result included
8578 articles from eight databases. The number of duplicate articles in all databases was 626. The first
process was to select articles based on a relevant keyword selection filter, which resulted in 1141 articles.
The second process was to select articles based on title and then map inclusion and exclusion criteria,
resulting in 351 articles. The third process carried out was to select articles by abstract, reading each
one for its selection, which resulted in 275 articles. The final process was to read all the articles in their
entirety, with only 48 articles meeting the inclusion and exclusion criteria.

4. Discussion
4.1. Techniques
In Table 2 shows results of analyzes techniques from 45 papers according to 1st, 2nd 3rd query from
Table 1 using methodology in section of methods. The first 17 papers from Table 2 shows most used
algorithms for the recognition of social distancing are YOLO, Faster R-CNN and SSD with evaluations
oriented on the average accuracy (mAP) and FPS to compare which algorithm gives better results in
different environments. [12, 13, 14, 15, 16, 17, 18, 10, 19, 20, 21, 22, 23, 24]. YOLO is the most used
algorithm, with the percentage of use by versions being (YOLO V2 is with 5%, YOLO V3 with 75% and
YOLO V4 with 10%), but those that use (F-RCNN and SDD) [25, 26, 24, 27, 21] go for the performance
side and response time in FPS with higher results. Regarding the versions, it can be seen that there is a
tendency to look for the latest updates.

   Then 22 papers from Table 2 shows most used algorithms for face mask detection as YOLO, Mobile
Net, ResNet, and topen-source computer vision library of python OpenCV. YOLO V3 [28], YOLO V4 [29]
[30] and YOLO V5 [31] [11]; last one shows a high level of accuracy, major that 95%. After the analysis,
it can notice the article [32] has the highest accuracy with 99.7%, the algorithm used was MobileNetV2
with the dataset Face-Mask-Detection. Last 6 papers from Table 2 shows about proposal that include face
mask detection and social distancing where it is analyzed 4 of them work with YOLO V3 [9, 6, 7, 8], with
an average of 94.5% accuracy corresponding to the test evaluation scope; Faster R-CNN algorithm [9],
with an average accuracy of 99%; MobileNet algorithm [10] with an average of 99%, YOLO V5 [11], with
a precision/recall of 0.6/0.98 and finally the ResNet algorithm [10, 7, 11], with an average of 98.5%.

4.2. Datasets
In Table 4 includes a short description of the research purpose of Face mask dataset. In addition, it
shows the principal classes used, images, labels, total weight, metrics and access type. Next in Table 3
shows a brief of the main features of social distancing dataset as: Duration, resolution, weight, metric
and access type.

4.3. Challenges and limitations
The studies carried out to develop applications that use artificial intelligence techniques present many
challenges and limitations in research repositories that must be addressed with urgency and interest.
The current challenges are related to the transmission and contagion of COVID-19 due to the lack of

knowledge and complexity of this epidemic. Databases on COVID-19 are difficult for researchers to
access and have characteristics that often do not meet the needs of researchers or are synthetic databases.
Database construction requires the processing of large volumes of data that includes manual evaluation
of unstructured data. Other challenges are related to the transparency of information from governments
and public entities in charge of sanitary control, which could generate a bias in the results. Another
challenge present in research is the similar behavior of COVID-19 with other traditional diseases. Points
to take into account in the correct detection and accuracy given that there are inconveniences such
as children or babies because most of the measurements are not detected within the ’person’ regime.
Another important point to take into consideration with the shadows, given that in some detections
made by the angle of the camera, it is filtered as a person itself. These are cases that cause an impact
within the percentage of final accuracy for applications.

4.4. Recommendations
The objective of this research is to help researchers learn about research on artificial intelligence issues
and limitations and advances to mitigate the contagion of the pandemic generated by COVID-19 and
thus be able to contribute to generating new research. Studies, such as the one by [32] propose a deep
convolutional neural network (CNN) based on the MobileNetV2 architecture as a learning algorithm.
The results show an accuracy of 99.7 % in mask detection with a run time of 1.54 s. Another study [46]
uses ResNet-18; with 99.05% accuracy in the classification of protective masks. Finally [10] focuses
on implementing a face mask detection and social distancing model as an integrated vision system.
Pre-trained models such as MobileNet, ResNet Classifier, and VGG with an F1 score of 99%, a sensitivity
of 99%, a specificity of 99%, and an accuracy of 100%.


5. Conclusions
The research carried out allows knowing the technological advances in the area of artificial intelligence
aimed at solving problems generated by COVID-19. This research analyzed the different solution pro-
posals based on mask detection algorithms and social distancing methods, considering the performance
of machine learning models. Additionally, recommendations were established that will serve as a guide
for the selection of research proposals in the area of artificial intelligence that try to solve problems of
COVID-19. Finally, it is suggested to use specific terms in database queries to obtain optimal results
considering the quotes and logical connectors.
