Due to the absence of any specialized drugs, the novel coronavirus disease or Посетить страницу источник is one of the biggest threats to mankind Although the RT-PCR test is the gold standard to confirm the presence of this virus, some radiological investigations find some important features from the CT scans of the chest region, which are helpful to identify the suspected COVID patients.
This article proposes a novel fuzzy superpixel-based unsupervised clustering approach that can be useful to automatically process the CT scan images without any manual annotation and helpful in the easy interpretation. The proposed approach uses a novel superpixel computation method which is helpful to effectively windows 10 1703 download iso italy covid symptoms the pixel intensity information which is beneficial for the optimization process.
Superpixels are further clustered using the proposed fuzzy artificial cell swarm optimization approach. So, a twofold contribution can be observed in this work which is helpful to quickly diagnose the patients in an unsupervised manner so that, the suspected persons can be isolated at an early phase to combat the spread of the COVID virus and it is the major clinical impact of this work. Both qualitative and quantitative experimental results show the effectiveness of the proposed approach and also establish it as an effective computer-aided tool to fight against the COVID virus.
On average, the proposed approach achieves 1. The general direction of this research is worthwhile pursuing leading, eventually, to a contribution to the community. Automated computer-aided systems prove their effectiveness and real-life applicability in various scenarios. Automated systems have a diverse domain of applications and sometimes, these systems are inevitable to perform certain jobs efficiently and in a cost-effective and highly time-bound manner.
This domain is evolving day-by-day and continuous effort can be observed from various researchers to enhance this domain. Windows 10 1703 download iso italy covid symptoms systems can be categorized in two ways. The first one is the supervised approach in which some properly annotated data are required to perform the classification and interpretation job [1][2]. Therefore, these automated systems are dependent on the ground truth data typically produced by some domain experts.
But, it may not be always possible to acquire the properly annotated ground truth data due to the involvement of human experts [3]. Sometimes, some cases are not well-defined or not seen earlier, на этой странице therefore, it is very difficult to get some ground truth data for those cases.
Unsupervised systems can windows 10 1703 download iso italy covid symptoms helpful in this context because these systems are not dependent on the ground truth data and can automatically explore some patterns from the underlying dataset by utilizing the windows 10 1703 download iso italy covid symptoms knowledge [4][5][6][7].
So, the unsupervised approaches are helpful in those situations where a sufficient amount of properly annotated ground truth data продолжить not available. The unsupervised computer-aided systems are widely applied in different domains of research [8][9]. Biomedical image analysis is no exception and exploits the advantages of unsupervised automated systems in various phases.
Radiology is one of the important and frequently used parts of the biomedical imaging domain which is serving as an important tool for noninvasive diagnostic systems. X-ray, CT Scan, etc. Automated systems are helpful to analyze and diagnose different patients automatically and automated radiological image analysis systems are also helpful in preparing precise and timely reports by reducing the human intervention and also reducing some unintentional human-made errors. Physicians, radiological technicians, and all other concerned domain experts can be significantly benefitted from the advancement in the field of computer-aided radiological image analysis systems.
Apart from the automated analysis of the radiological images, computer-assisted systems can be helpful in parameter tuning of the image acquisition hardware, image preprocessing, quality control, selecting the appropriate level of radiation, and many more.
Therefore, automated systems can act as a helping hand in the decision-making process. In Table 1 windows 10 1703 download iso italy covid symptoms of the related biomedical image segmentation works of literature are discussed which is helpful in a better understanding of the current trend and status of the same.
Apart from these works, some comprehensive studies can be found in [13][14][15][16][17]. Apart from these works, some of the most recent and relevant works can be found in [28][29][30][31][32] that can be referred to, to understand the further advancements of this domain. In this context, it is worth mentioning here that the active contour model is an effective way of image segmentation. There are several variations available of this approach. The traditional active contour approach was proposed in [33].
A modified version of the traditional active contour approach is proposed in [34] and it is known as geometric active contours. This approach uses gradient information of an image windows 10 1703 download iso italy covid symptoms construct the edge stop function. A region information-based approach is proposed in [35]. This approach is developed by Chan and Vese and this is a parametric representation. Some deep learning approaches are developed that use the loss function of the active contour model as their loss function [36].
Although the mortality rate is not very high, the highly infectious nature of this virus is the main threat to society. Due to the absence of any specialized drug, it is very difficult to restrict the drastic spread of this virus. Apart from using various protective equipment, early detection and isolation can be very effective to combat the spread of this highly infectious virus.
In the middle of this pandemic scenario, some vaccines are invented and are being applied to the people and it is a ray of hope to fight against this virus. As per the report of the world health organization, , numbers windows 10 1703 download iso italy covid symptoms confirmed cases can be observed in countries and 4, people are already expired due to this disease as of 15th Octoberpm CEST [40].
From these statistics, it is clear that windows 10 1703 download iso italy covid symptoms worldwide mortality rate основываясь на этих данных approximately 2.
The major risk factor lies in the highly infectious nature of this virus. Hopefully, 6,, vaccine doses have already been administered worldwide which may be helpful in reducing the mortality rate. Many countries are not prepared with the appropriate infrastructures to support COVID infected patients. Moreover, many people from remote areas are not even able to arrange protective gear like masks, sanitizers, etc. The reverse transcription-polymerase chain reaction test i.
It is a quite inspiring finding because CT scan images can be used to isolate some suspected patients at an early phase and therefore, the drastic spread of this virus can be stopped to some extent. The presence of some prominent features like ground-glass opacities, crazy paving, etc. Typically, the absence of properly annotated data makes the automated biomedical image analysis job difficult.
As the name suggests, the proposed approach is based on the superpixels and type 2 fuzzy systems where the type 2 fuzzy objective function is modified to incorporate the advantages of superpixels to efficiently process a large amount of spatial information.
The fuzzy objective function is optimized with the recently developed metaheuristic procedure i. The proposed method allows automated and efficient analysis of the CT scan images which is beneficial to enhance http://replace.me/11380.txt computer-aided diagnostic systems to act as a tool against the COVID virus.
To summarize, the major contributions are as follows: 1 A novel superpixel-based image segmentation technique is proposed that reduces the incurred computational cost for processing a high amount of spatial information, 2 Type-II fuzzy system is incorporated with the superpixel-based approach, 3 A recently developed metaheuristic procedure ACSO is further enhanced, 4 The conventional fitness function of the FCM clustering approach is enhanced to exploit the advantages of superpixel 5 The cluster centers are updated with the help of the proposed fuzzy ACSO approach.
The remaining article is prepared in the following way: Sections 23 describes the artificial cell swarm optimization method and the type 2 fuzzy clustering framework respectively. Section 6 discusses some of the relevant points and a brief conclusion is presented in Section 7.
This is a recently developed metaheuristic procedure адрес страницы is inspired by the artificial cell division procedure. The artificial cell swarm optimization procedure mimics the artificial cells as the search agents. The actual artificial cell division approach [46] is slightly modified to design the optimization procedure.
The incorporated modifications are listed below [47] :. The hierarchical tree structure is formed throughout the generations due to the artificial cell division process. Swarms of artificial cells are considered in the optimization process to take part in the привожу ссылку cell division process.
No communication is allowed between any pair of artificial cells. Lifespan of the k th artificial cell at a certain timestamp t s is an important parameter and it is directly dependent on the fitness value f i t n e s s k здесь given in Eq.
A huge number of powerpoint free download 2019 can significantly increase the fitness evaluations and a small number of swarms can increase time to converge and therefore, is essential to decide the swarm count moderately. In this work, the swarm читать is considered is a fixed parameter.
One artificial cell can produce some new cells and the production of new cells occur at a certain distance which is inversely dependent on the fitness of the producer cell as expressed in Eq. The distance between the k th cell and any of the l th cell, which are produced from the same parent cell, must be same. Therefore, if a cell is near to global optima, then it can generate some other cells at a smaller distance and vice-versa.
Windows 10 1703 download iso italy covid symptoms steps help to search the nearest portions of the global optima cautiously so that the global optima may not be missed accidentally. A cell does not have any effect on the population once its lifespan is over. This property helps to maintain the size of the population and prevents getting overpopulated. The successor cells of a cell can produce some other cells by the cell division process to maintain the population. The life span of a cell can belong it belongs to the near-optimal area.
The quality of a population is evaluated using the lambda function which is given in Eq. Algorithm 1 illustrates the artificial cell swarm optimization approach in brief [47]. The proposed approach adopts the type 2 fuzzy logic-based clustering approach to effectively windows 10 1703 download iso italy covid symptoms and handle the random uncertainties. In most real-life applications, the uncertainty cannot be predicted in advance.
A wide range of input types can produce random uncertainties. Hence, it is essential to cope up with the random uncertainties in real-life scenarios. The fuzzy C-means clustering approach is one of the widely used clustering approaches which is suitable to various problems of different domains [48][49][50][51].
The main reason behind the increasing popularity of fuzzy systems is the suitability of this approach in different scenarios where the crisp clustering approaches do not perform well. A single point can be a member of more than one cluster at the same time with some membership values. The total sum of all membership values for a certain point must be one. So, the value of the membership can be anything between 0 and 1.
The dissimilarity function which is optimized by the fuzzy C-means clustering approach is given in Eq. The cluster centers can be updated using Eq. The type 2 fuzzy logic systems use separate sets of membership values that are also fuzzy in nature. This approach allows efficient modeling of dynamic input uncertainties by providing additional degrees of freedom. In this work, the type 2 fuzzy logic-based clustering approach is adopted to overcome some of the common problems of type 1 fuzzy systems like noise sensitivity, relative membership values, etc.
It is essential to improve the outcome of the segmentation process. Windows 10 1703 download iso italy covid symptoms uncertainty of a point must be decided depending on the membership value i. So, windows 10 1703 download iso italy covid symptoms lower membership value indicates higher uncertainty and vice-versa.
