Mammography is the primary modality that helped in the early detection and diagnosis of women
breast diseases. Further, the process of extracting the masses in mammogram represents a challenging task
facing the radiologists, due to problems such as fuzzy or speculated borders, low contrast and the presence of
intensity inhomogeneities. Aims to help the radiologists in the diagnosis of breast cancer, many approaches
have been conducted to automatically segment the masses in mammograms. Towards this aim, in this paper,
we present a new approach for extraction of tumors from region-of-interest (ROI) using the algorithm of Fuzzy
C-Means (FCM) setting two clusters for semi-automated segmentation. The proposed method meant to select
as input data the set of pixels that enable to get the meaningful information required to segment the masses
with high accuracy. This could be accomplished through eliminating unnecessary pixels, which influence on this
process through separating it outside of the input data using an optimal thresho ld given by monitoring the
change of clusters rate during the process of threshold decrementing. The proposed methodology has
successfully segmented the masses, with an average sensitivity of 82.02% and specificity of 98.23%.

The search for improvement in the result of segmentation of regions of interest in medical images has continued to be a source of challenge to researchers. Several research efforts have gone in to delineate regions of interest in the prostate gland from Trans-rectal ultrasound (TRUS) 2D-images. In this work, we develop a fast algorithm based on radial/axial scanning of the pixels of the prostate gland image with the goal of detecting hyper-echoic pixels that are bound within the boundaries of the gland TRUS 2D-images. The algorithm implements expert knowledge and utilizes the features extracted from the intensity of the TRUS images, primarily the relative intensity and gradient to delineate region of interest. It employs radial/axial scanning of the image from common seed point automatically selected to detect the region of the gland and subsequently hyper-echoic pixels which indicate suspected cancerous tissue cites. Evaluation of the algorithm performance was done by comparing detection result with that of expert radiologists. The detection algorithm gave an average accuracy of 88.55% and sensitivity of 71.65%.

Early Detection of Lung Cancer Using Neural Network TechniquesIJERA Editor
Effective identification of lung cancer at an initial stage is an important and crucial aspect of image processing. Several data mining methods have been used to detect lung cancer at early stage. In this paper, an approach has been presented which will diagnose lung cancer at an initial stage using CT scan images which are in Dicom (DCM) format.

Classification techniques using gray level co-occurrence matrix features for ...IJECEIAES
Lung cancer, which causes the majority of fatalities worldwide each year, is one of the deadliest diseases. The survival rate of cancer patients could be improved with better cancer detection methods. Image processing and machine learning have both been used to aid in lung cancer detection, but a method that both increase accuracy and increases a patient’s survival rate has yet to be identified. In an effort to find the most effective method for the accurate lung cancer recognition, this paper analyses and compares several classification algorithms. Lung computed tomography (CT) images are enhanced by removing noise using a median filter. For filtered image, threshold segmentation is used to segment it into distinct parts. From the segmented image different features are extracted using the grey level co-occurrence matrix (GLCM). several classification strategies, including support vector machine (SVM), random forest (RF), k-nearest neighbor (KNN), and decision tree (DT) methods, are used to classify lung images as malignant or normal based on the extracted features. Methods are evaluated based on a number of various performance measures, like accuracy, a precision, the recall, and the F1-Score. Based on the experimental outcomes, SVM outperforms other classification methods in accurately detecting lung cancer with an accuracy of 99.32%.

Considering Two Sides of One Review Using Stanford NLP Frameworkrahulmonikasharma
Sentiment analysis is a type of natural language processing for tracking the mood of the public about a particular product or a topic and is useful in several ways. Polarity shift is the most classical task which aims at classifying the reviews either positive or negative. But in many cases, in addition to the positive and negative reviews, there still many neutral reviews exist. However, the performance sometimes limited due to the fundamental deficiencies in handling the polarity shift problem. We propose an Improvised Dual Sentiment Analysis (IDSA) model to address this problem for sentiment classification. We first propose a novel data expansion technique by creating sentiment-reversed review for each training and test review. We develop a corpus based method to construct a pseudo-antonym dictionary. It removes DSA’s dependency on an external antonym dictionary for review reversion. We conduct a range of experiments and the results demonstrates the effectiveness of DSA in addressing the polarity shift in sentiment classification. .

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Abstract— Mass segmentation methods are commonly used nowadays in modern diagnostic centers and research centers working in the field of
lung cancer detection and diagnosis. We have implemented k-means and fuzzy cluster means (FCM) techniques for mass segmentation of lung
CT images. The methods were compared in terms of area, perimeter and diameter. FCM outperforms K-means in terms of better detection of
lung cancer area and effective values of dimensional features of lung cancer as compared to K-means method.
Keywords- Computed tomography (CT), Fuzzy c-means (FCM), K-means.

I. INTRODUCTION
Presently low dose CT is the core interest area for detection of
lung cancer. Mass region detection is a rising research work
field that has received continuous focus in the research group
over the past decades. Image segmentation is a process to
partitioned digital image into several regions [1-9]. Each of the
pixels in the region has same characteristics like color,
intensity, texture etc. For early diagnosis of lung abnormalities
CT images are widely used by radiologist to detect cancer
nodule with some feature such as area, diameter and size
[13].The efficient segmentation algorithm provides good
accuracy and higher decision confidence value to the
radiologist to make better remark. There are several issues
related to image segmentation that required detailed review of
literature. The most important part of image segmentation is to
detect the proper area of mass by selecting suitable method for
isolating different object from the background. The two
existing clustering techniques have been used for segmentation
purpose but for actual segmentation some morphological
operation has been used over clusters. The performance of
these two techniques is also evaluated and results are screened.
Judice et al. (2013) presented an automated computer added
diagnosis (CAD) system in which wiener filter is used to
remove noise. Hidden Markov Model algorithm was proposed
which increase the confidence level of diagnosis and taken less
time also[5].
Maivizhi et al. (2013) used K-means and Fuzzy c-means
algorithm to find out cancer affected gene and proposed
modified fuzzy c-means algorithm to grasp cancerous nodule.
An experimental system has been implemented and tested to
demonstrate the effectiveness of proposed method on the basis
of parameter such as no of cluster, time, space and
performance calculation and cluster evolution [9]. Niranjana et
al. (2014) worked on Neural fuzzy Network (NFN) and a
Fuzzy c-mean (FCM) clustering algorithm for segmenting the
early stage of lung cancer. A thresholding technique as a pre-
processing step in all images to extract the nuclei regions was
applied, because most of the quantitative procedures are based
on its nuclei feature. This thresholding algorithm had
succeeded in extracting the nuclei regions. Moreover, it
succeeded in determining the best range of thresholding
values. The NFN and FCM methods are designed to classify
the image of N pixels among M classes and tested over many
color images, and NFN has shown a better classification result
than FCM [11]. Kumar et al. (2013) compared Artificial
Neural Network (ANN), Fuzzy C-Mean (FCM) and Fuzzy
Min-Max Neural network (FMNN) which is very effective and
helpful in cancer diagnosis for its several advantages. The
motive behind that the fault tolerance, flexibility, non linearity
are the factors of artificial neural network. FCM provides
finest findings for overlapped data set; data point may be
connected with more than one cluster centre. Non-linear
separability, soft and hard decision, less training time, online
adaptation is the advantages of FMNN. The classification
methods are applied to both FMN and FCM on the X-ray 130
cancerous and noncancerous datasets available. Hence using
FCM and FMNN to diagnose lung cancer is good[12].
Jaffer et al. (2009) proposed a method by using Fuzzy c-mean
(FCM) and morphological techniques for detection of tumor
from lung computed tomography (CT) images. Initially, the
automated segmentation of lungs has been done using fuzzy.
Region of interests (ROIs) have been extracted by using 8
directional searches slice by slice and then 3D ROI image
have been constructed. A 3D template has been constructed
and convolves with the 3D ROI image. Finally FCM have
been used to extract ROI that contain nodule. The technique
was tested against the 50 datasets of different patients received
from Aga Khan Medical University, Pakistan and Lung Image
Database Consortium (LIDC) dataset [22]. Patel et al. (2010)
developed an adaptive k means clustering algorithm for
mammographic images segmentation for detection of breast
cancer at early stage. The feature extraction is performed with
the data base of 150 breast cancer images taken from BSR

APPOL with the parameter such as number, color and shape of
object[23].
Fatma et al. (2011) presented Hopfield Neural Network (HNN)
and a Fuzzy c-mean (FCM) clustering algorithm, for
segmenting sputum color images for detection of lung cancer in
early stages. The above methods are designed to classify the
image of N pixels among M classes. They used 1000 sputum
color images to test both methods, and HNN has shown a better
classification result than FCM, the HNN succeeded in
extracting the nuclei and cytoplasm regions [33]. Kaur et al.
(2015) reviewed two methods i.e. Neural Network (NN) and
Fuzzy c-mean Clustering Algorithm for sputum color images
for early diagnose of lung cancer. They compared these two
methods with their advantage and disadvantage and conclude
that Fuzzy c-mean (FCM) clustering algorithm is not good at
low intensity variations [35].
II. PROPOSED METHODOLOGY
The proposed method follows several steps which include
taking input image for pre processing for removal of noise and
enhance the contrast of input image for better segmentation
Fig. 1: Flow diagram of proposed system
using various clustering techniques such as K-means and
Fuzzy c-means. To find out accurate mass region process such
as binary, dilation, erosion, opening and closing are performed
step by step on each image. Finally, evaluate parameter like
area, diameter and perimeter for comparison of better method.
The flow diagram of proposed system has shown in Fig. 1.
III. RESULTS AND DISCUSSION
In this work we have compared two clustering techniques K-
means and FCM for better lung mass segmentation in CT
images that are used in CAD system. Both the methods are
compared with several morphological operation and from the
Fig. 2 it has been notice that the K-means techniques gives
little bit smooth rounding edges for suspected nodule whereas
FCM bordered more accurately because cancer nodule has not
any specific size and somehow in zigzag pattern. The
parameter such as area, perimeter and diameter calculated by
FCM are more accurate as compare to K-means for each
nodule. These parameters calculating by K-means is lesser due
to smooth surfacing in nodule but FCM calculate these
parameter values for each nodule efficiently which helps to
further classify the nodule for T staging. Both the techniques
gives prominent result but FCM is better for marking proper
suspected area in case of single and multiple nodule detection
in CT image of lung The comparative study of K-means and
Fuzzy c-means algorithms in terms of several parameters such
as area, diameter and perimeter has been evaluated.
Experimental data have been consisting of more than 50
images and comparative results of 6 images are shown in
Table 1.
