## Abstract

Lung disease is one of the most harmful diseases in traditional days and is the same nowadays. Early detection is one of the most crucial ways to prevent a human from developing these types of diseases. Many researchers are involved in finding various techniques for predicting the accuracy of the diseases. On the basis of the machine learning algorithm, it was not possible to predict the better accuracy when compared to the deep learning technique; this work has proposed enhanced artificial neural network approaches for the accuracy of lung diseases. Here, the discrete Fourier transform and the Burg auto-regression techniques are used for extracting the computed tomography (CT) scan images, and feature reduction takes place by using principle component analysis (PCA). This proposed work has used the 120 subjective datasets from public landmarks with and without lung diseases. The given dataset is trained by using an enhanced artificial neural network (ANN). The preprocessing techniques are handled by using a Gaussian filter; thus, our proposed approach provides enhanced classification accuracy. Finally, our proposed method is compared with the existing machine learning approach based on its accuracy.

## 1. Introduction

Lung disease is one of the major diseases nowadays, so the early detection and prevention of the disease are more crucial; many researchers are involved to create more and more algorithms in detecting the accuracy of lung disease classifications. In simple words, lung diseases are considered a disorder that arises from different categories, and then the various types of diseases are found in the lung disease classifications, namely, asthma, COPD, infections like influenza, pneumonia, and tuberculosis, lung cancer, and many other breathing problems. The most common types of lung cancer are lung nodules, non-small-cell lung cancer, and mesothelioma. There are two types of lung cancer, namely, small cell lung cancer and non-small cell lung cancer [1–3].Non-small-cell lung cancer is further divided into three types, and these are all considered the normal form of the disease; thus, the carcinoma type has various types, namely, large cell carcinoma and squamous cell carcinoma; and adenocarcinoma is the most common lung cancer that is found all over the world. The Internet of Things plays a vital role in lung disease classifications and the artificial intelligence protocol plays an important role in the form of cell diseases. The researcherused the form of the support vector machine, the fuzzy-based clustering, and the K nearest neighbor technique to predict the better accuracy of the diseases, but it could not produce a better accuracy of the classifications. Thus, our paper implements an artificial neural network for the classification of the given datasets, and the feature extraction is detected by using particle swarm optimization. Artificial neural networks (ANNs) are statistical models that simulate the learning dynamics of the brain by replicating the biological organization of neural cells through a mathematical structure. Although there may be a variety of definitions for the term “ANN,” it typically refers to a neural network used for modeling nonlinear statistical data. The neural models used today in a variety of medical specialties, including oncology, are effective models for nonlinear regression or classification and do not seek to be physiologically realistic in every detail. Applications for ANN inference exist in tasks that demand attention and focus. The success of ANNs in clinical decision support depends critically on better integration with clinical protocols, awareness of the necessity of combining various paradigms to produce the overall reasoning structure that is the simplest and most transparent, and the willingness to test this in a real clinical setting. We have evaluated the evidence supporting advancements in the application of ANN in lung cancer research [4–14].

Thus, our paper provides an enhanced output when compared to the other existing techniques.


## 2. Overview of the Proposed Approach

The overview of the proposed approach explains the basic concepts of image processing. Figure1 implements that the overview of the proposed approach and the basic concepts of image processing are expressed clearly as the image processing techniques consist of the four major concepts, namely, preprocessing, segmentation, feature extraction, and classification techniques. The proposed artificial neural network provides enhanced results on the basis of feature extraction in image processing. Our proposed approaches imply the accuracy of classifications of lung diseases.Figure 1
Overview of the proposed approach.After the completion of feature extraction, the classification techniques take place. Our paper shows that the artificial neural network with the PCA methods is used to improve the classification accuracy when compared to the existing techniques.


### 2.1. System Model

The preprocessing technique is one of the important techniques in the image processing; the main function of the preprocessing technique is to help reduce the noise in the images and also enhance the RGB to the grey scale conversion in the images. In our proposed method, a Gaussian filter is used for removing the noise in the images.The Gaussian filter is nothing but a low-pass filter, which helps to reduce the noise in the filter and also helps to reduce the blurred images. It helps to enhance the quality of the images; thus, the output of the Gaussian images helps to easily enhance the feature extraction processes.(1)Gx=12∗3.14α2ey,y=x22σ2.The above equation shows Gaussian functions of image processing.


#### 2.1.1. Particle Compound Analysis

Normally, feature extraction is used to extract the given dataset images into a group of manageable images, and then, this provides better-enhanced results when compared to the other existing techniques [8]. This paper shows that feature extraction is used for both dimensional reduction and the feature reduction process. It enhances the quality of the images and reduces the blurring in the image. This paper implements the conditions of(2)P≤m,where P is considered as the number of the significant principal components and m is considered as all the principal components. The above conditions imply that the principle compound analysis is used for the dimensional reduction, or it provides the lower dimensional in the entire image processing system. Let us assume that the datasets Y and P are considered as the principal compound analyses and T is considered as the covariance of the eigenvectors,(3)1≤P≤m.


#### 2.1.2. Discrete Fourier Transform

Normally, the mathematical expression in image processing can be used for the conversion of the signals at the given frequency, accurately; thus, this paper implements the DFT for feature extraction. The stethoscope sounds are generated in various domains and at various frequencies; in the form of the DFT transform, they are transferred at the given signal separately.Thus, this function helps to predict the better accuracy of the classification obtained in this paper. Thus, the DFT transform does not give better results in the digital region. The form of medical image processing, especially in the lungs diseases classifications, provides enhanced accuracy classification results.(4)Sr=∑K=0N−1XkExp−2∗3.14jrkNr=0,…..N−1,where n denotes the number of samples and Sr denotes the DFT coefficient. Figure 2 shows the proposed artificial neural network approach. The presented artificial neural network approaches demonstrate that the input data samples are preprocessed using the Gaussian filter. In the image processing technique, the Gaussian noise is introduced into the input images in the usual ways and is removed using the Gaussian filter. After the preprocessing procedures are finished, feature extraction techniques are used. In certain circumstances, feature reduction is regarded as the key idea, which lowers the need for dimensional reduction throughout the entire image processing process. Since feature extraction is the key idea, it reduces the dimensional spaces throughout all the photos and then offers image sharpening and smoothing.Figure 2
