Review of Image Segmentation Techniques based on Region Merging ApproachEditor IJMTER
Image segmentation is an important task in computer vision and object recognition. Since
fully automatic image segmentation is usually very hard for natural images, interactive schemes with a
few simple user inputs are good solutions. In image segmentation the image is dividing into various
segments for processing images. The complexity of image content is a bigger challenge for carrying out
automatic image segmentation. On regions based scheme, the images are merged based on the similarity
criteria depending upon comparing the mean values of both the regions to be merged. So, the similar
regions are then merged and the dissimilar regions are merged together.

An Automated Solution for Extracting and Counting of White Blood Cells in a B...ijtsrd
There are various tools present commercially for automatic counting of Blood Cells. These tools are used for counting and finding the different types of Blood Cells present in the Blood Smear. The count of White Blood Cells is important for detecting various diseases as well as to follow the accurate treatment for the diseases like Anemia, Leukemia, Inflammation, Systemic illness, Allergy and Burn-Induced etc. The White Blood Cell count gives the vital information about the diseases which is used for diagnosing the patients. The old conventional method of counting White Blood Cells under microscope gives an inaccurate and unreliable results depending upon how the laboratory technician works on it. Another method for White Blood Cell counting is done through cell counter machine, which is very expensive and cannot be afforded to remote rural areas, hence to overcome such problems this paper proposes a cost-effective approach, i.e, automated solution using smart phone based solution for extracting and counting of White Blood Cells.

Detection and classification of blood cancer from microscopic cell images usi...IJARIIT
Leukemia is a cancer of the blood and bone marrow, the spongy tissue confidential the bones where blood cells are
made. Acute myeloid leukemia (AML) is one of the most common types of leukemia among adults. The signs and symptoms of
leukemia are non-specific in nature and also they are comparable to the symptoms of other mutual disorders. Manual
microscopic inspection of stained blood smear or bone marrow aspirate is the only way to an effective diagnosis of leukemia.
But this method is time consuming and less accurate. In this paper, a technique for automatic detection and classification of
AML in blood smear is presented. K-means algorithm is used for segmentation. KNN, NN, and SVM are used for
classification. GLCM is used for optimizing the spectral features. The local binary pattern is used for texture description.
Blood microscope images were tested and the performance of the classifier was analyzed.
Investigation of white blood cell biomaker model for acute lymphoblastic leuk...journalBEEI
Acute Lymphoblastic Leukemia (ALL) is a disease that is defined by uncontrollable growth of malignant and immature White Blood Cells (WBCs) which is called lymphoblast. Traditionally, lymphoblast analysis is done manually and highly dependent on the pathologist’s skill and experience which sometimes yields inaccurate result. For that reason, in this project an algorithm to automatically detect WBC and subsequently examine ALL disease using Convolutional Neural Network (CNN) is proposed. Several pretrained CNN models which are VGG, GoogleNet and Alexnet were analaysed to compare its performance for differentiating lymphoblast and non-lymphoblast cells from IDB database. The tuning is done by experimenting the convolution layer, pooling layer and fully connected layer. Technically, 70% of the images are used for training and another 30% for testing. From the experiments, it is found that the best pretrained models are VGG and GoogleNet compared to AlexNet by achieving 100% accuracy for training. As for testing, VGG obtained the highest performance which is 99.13% accuracy. Apart from that, VGG also proven to have better result based on the training graph which is more stable and contains less error compared to the other two models.
Leukemia Blood Cancer Detection Using MATLABChristo Ananth
Christo Ananth, P. Thenmozhi, Stalin Jacob, Dr.A. Anitha, “Leukemia Blood Cancer Detection Using MATLAB”, Turkish Journal
Christo Ananth et al. discussed about detection of leukaemia using a small picture handling method that distinguishes between red blood cells and young white cells. Visual examination of minuscule photos by looking at alterations such as surface, calculation, shading, and measurable research of photographs is now the only recognisable proof of blood trouble. One of the leading causes of death in humans is leukaemia. Its success rate and prognosis are largely dependent on the early detection and detection of infection. The goal of this project is to identify and test leukemia-affected cells. Leukemia can be recognised and classified based on the presence of juvenile cells, as well as whether it is persistent or intense. A variety of procedures, including histogram levelling, straight difference extending, and morphological methods such as region opening, region closing, disintegration, and expansion, are used to differentiate juvenile cells. When compared to current procedures, the Proposed Method has produced better results.

Description:
Christo Ananth et al. discussed that Blood leukemia can be diagnosed with greater precision and specificity when red blood cells are separated from young white blood cells. The only way to tell if someone has a blood disorder is to take photographs of their skin, calculate, shade, and measure them. According to the World Health Organization, leukemia is the fifth leading cause of death in the world. Early detection and identification of infection are critical to the treatment's success and outcome. It is hoped that the researchers will be able to identify and test cells that are linked to leukemia in this study. This disease can be classified according to whether or not it has immature cells and the severity of persistent or intense leukemia. A more uniform distribution of data points can be achieved by using histogram levelling and straight difference extending with morphological methods such as region opening, region closing, disintegration, and expansion. Thus, the Proposed Method is more effective than other previous methods.
Classification of Leukemia Detection in Human Blood Sample Based on Microscop...ijtsrd
Nowadays, the automatic specific tests such as Cytogenetics, Immunophenotyping and morphological cell classification can identify the leukemia disease by making experienced operators observing blood or bone marrow microscopic images. The early identification of Acute Lymphoblastic Leukemia ALL symptoms in patients can greatly increase the probability of recovery. When typical symptoms appear in normal blood analysis, those methods are not included into large screening programs and are applied only. The method of blood cell observation using Cytogenetics and Immunophenotyping diagnostic methods are currently preferred for their great accuracy with respect to present undesirable drawbacks slowness and it presents a not standardized accuracy since it depends on the operator's capabilities and tiredness. The detection of leukemia in human blood sample using microscopic images is suitable for low costs and remote diagnosis systems. In this paper presents an implementation of detection and classification of leukemia. The system will use features in microscopic images and examine changes on texture, shape and color analysis. Support Vector Machines SVM is used as a classifier, which classifies into cancerous or not. The detection and classification of ALL is implemented with MATLAB programming language.

Computer Aided Diagnosis for Screening the Shape and Size of Leukocyte Cell N...IJECEIAES
Hematology tests are examinations that aim to know the state of blood and its components, one of which is leukocytes. Hematologic examinations such as the number and morphology of blood generally still done manually, especially by a specialist pathologist. Despite the fact that today there is equipment that can identify morphological automatically, but for developing countries like Indonesia, it can only be done in the capital city. Low accuracy due to the differences identified either by doctors or laboratory staff, makes a great reason to use computer assistance, especially with the rapid technological developments at this time. In this paper, we will emphasize our experiment to screen leucocyte cell nucleus by identifying the contours of the cell nucleus, diameter, circumference and area of these cells based on digital image processing techniques, especially using the morphological image. The results obtained are promising for further development in the development of computer-aided diagnosis for identification of leukocytes based on a simple and inexpensive equipment.
PPT-Detection of Blood Cancer in Microscopic Images of Human Blood.pptxdevnamu
Identifying the leukemia type at an early stage is essential in determining the most appropriate treatment for the specific type of leukemia. It is necessary to perform a complete blood count in order to detect leukemia. If the patient’s blood cells count is abnormal, it is recommended that they consult with a doctor. As a result, morpho-logical bone marrow and peripheral blood slide analyses are performed to confirm leukemic cells’ presence. When a hematologist examines some cells under a light microscope, he will look for abnormalities in the nucleus or cytoplasm of the cells, allowing him to classify the abnormal cells into the various types and subtypes of leukemia present in the sample. It is then up to a hematologist to sort out the abnormal cells and classify them according to the various types and subtypes of leukemia that have been diagnosed within the laboratory. According to this classi-fication, it is possible to predict the clinical behavior of the disease, and treatment should be admred to the patient following the predicted clinical behavior.

A survey on Energy Efficient ProtocolsLEACH, Fuzzy-based approach and Neural ...IJEEE
Wireless Sensor Networks (WSN) plays a very important role in transmitting the data from source to destination but energy consumption is one of the major challenges in these networks. WSN consists of hundreds to thousands of nodes which consume energy while transmitting the information and with a span of time whole energy get consumed and network life time gets reduced. Clustering and Cluster head (CH) selection are important parameters used to enhance the lifetime of the WSN. Clustering use two methods: rotating CH periodically in every round to distribute the energy consumption among nodes and the node with more residual energy becomes CH.This research paper is focused on the performance of the techniques used to enhance the energy efficiency in Wireless Sensor Networks (WSNs). Low- Energy Adaptive Clustering Hierarchy (LEACH), Fuzzy- Based and Neural Network are some of the important techniques used. MATLAB simulation tool is considered in this paper.

Automated Air Cooled Three Level Inverter system using ArduinoIJEEE
The output voltage of a three level inverter is stepped voltage in which the output voltage have three possible values. Such systems can be used to interface renewable energy sources with the grid. Temperature has significant effect on performance of power MOSFETs. Typically, the MOSFETs used as power switches in such applications are a significant source of heat, and the heat energy dissipated by these components must be carefully controlled if operating temperatures are to be maintained. So for the system to work efficiently cooling of MOSFETs is required. This paper proposed an automated air cooled 3 level H-bridge inverter. The system consists of MOSFETs, LM 35 temperature sensor, Optocouplers for isolation. Arduino is used to control the on-off operation of fan. When temperature rises above certain level fan turns on to cool the MOSFETs.

An Approach to Speech and Iris based Multimodal Biometric SystemIJEEE
Biometrics is the science and technology of human identification and verification through the use of feature set extracted from the biological data of the individual to be recognized. Unimodal and Multimodal systems are the two modal systems which have been developed so far. Unimodal biometric systems use a single biometric trait but they face limitations in the system performance due to the presence of noise in data, interclass variations and spoof attacks. These problems can be resolved by using multimodal biometrics which rely on more than one biometric information to produce better recognition results. This paper presents an overview of the multimodal biometrics, various fusion levels used in them and suggests the use of iris and speech using score level fusion for a multimodal biometric system.
An Overview of EDFA Gain Flattening by Using Hybrid AmplifierIJEEE
Data communication systems are increasingly engrossing optical fiber communication system as the transmission paths for the information, the information is in the form of light pulses sending from one place to another through the optical fiber. Several types of optical amplifiers have been developed in optical fiber communication system to amplify the optical signals. The erbium doped fiber amplifier is one of the optical fiber amplifiers which are used for long distance communication. The most significant points in any optical amplifier design are gain and noise figure. They are connected to one another. The other optical amplifier, Raman amplifier has wide gain bandwidth. The EDFA gain spectrum has variations over 1536 to 1552 nm, therefore the gain flattening is a research issue in recent years with the development of high capacity DWDM. The gain variation becomes a problem as the number of channels increases. The gain of EDFA depends on large number of device parameters such as, Erbium ion concentration, amplifier length, core radius, pump power. Raman amplifiers can be combined with EDFAs to expand the optical gain flattened bandwidth. This paper focuses on different methods used for the gain flattening.

In the past few years Autonomous vehicles have gained importance due to its widespread applications in the field of civilian and military applications. On-board camera on autonomous vehicles captures the images which need to be processed in real time using the image segmentation algorithm. On board processing of video(frames)in real time is a big challenging task as it involves extracting the information and performing the required operations for navigation.This paper proposes an approach for vision based autonomous vehicle navigation in indoor environment using the designed image segmentation algorithm. The vision based navigation is applied to autonomous vehicle and it is implemented using the Raspberry Pi camera module on Raspberry Pi Model-B+ with the designed image segmentation algorithm. The image segmentation algorithm has been built using smoothing,thresholding, morpho- logical operations, and edge detection. The reference images of directions in the path are detected by the vehicle and accordingly it moves in right or left directions or stops at destination. The vehicle finds the path from source to destination using reference directions. It first captures the video,segments the video(frame by frame), finds the edges in the segmented frame and moves accordingly. The Raspberry Pi also transmits the capture video and segmented results using the Wi-Fi to the remote system for monitoring. The autonomous vehicle is also capable of finding obstacle in its path and the detection is done using the ultrasonic sensors.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Abstract- Nowadays, many diseases which were incurable to
human become the main topic in every country. Solemn
illness that becomes killer to mankind was the kind that
cannot be detect early, no early symptoms, and can spread
throughout the body without notice. Sometimes, it can only
be realized after critical conditions. This kind of disease was
incurable and cause death to the infected person. One of the
challenges in medical science is to detect and identify
diseases for early detection by medical imaging technology.
Medical imaging modalities such as X- Ray, Computed
Tomography (CT) Scan, Magnetic Resonance Imaging
(MRI), and Ultrasound produce medical image captured
from human body arrangement for analysis and diagnosis.
In addition, analysis in medical field for diagnosis was done
by counting cells from microscopic images. Moreover, blood
related diseases such as anemia or leukemia due to lack or
extreme production of blood cells also become serious
illness which causes death. Early discovery of these
diseases needs to be done to reduce death rate. One of the
technologies used to solve the problem is by image
processing. However, this method required knowledge and
ability to apply many different methods in an analysis.
Therefore, a simple and easy method needs to be identified
to help clinician.
Index Terms- Blood cancer detection, Color based
clustering, WBC Count, K-means clustering.
I. INTRODUCTION
The main objective of this project was to determine the
easier and simple method for white blood cell (WBC)
extraction, and count the number of WBCs detected in blood
sample images. The scope of this project was to analyze on
fifty images of Blood cell having cancerous infection and
perform extraction and counting the number of WBC. It will
use clustering of each color part in the images and extracting
the affected area. To count the number of cell, we will
use grayscale intensity approach. This project will used
MATLAB image processing toolbox from Math Work.
While analysis, it was found that the affected area i.e. the
WBCs in any blood cell image has color as Dark blue, red,
violet and which can be extracted by using color based
clustering and extracting them from the rest of the image and
then counting the affected area. The foremost criteria of this
paper is counting the no. of WBC cells which helps people
in laboratory to declare if someone has blood cancer. In the
study of the blood cell images, it was found that the images
showing blood cells have WBCs as dark blue color. The k-
means clustering takes out clusters of three different colors
in the image. It makes sure that the resolution of the image is
not taken up for counting process.
A. BLOOD CELL DESCRIPTION
Blood circulatory system is one of the most important
systems in human‘s body. The function of this system is to
transport blood throughout the body. This system consists of
blood vessels which are arteries, veins, and capillaries, heart
that act as pumping system, and blood that act as the
medium for the system. Blood transportation is very
important in order to supply oxygen to our body, carries
carbon dioxide for gaseous exchange, minerals, nutrients,
and ensure healthiness. Blood cell composed of White
Blood Cells (WBCs), Red Blood Cells (RBCs), platelets,
and plasma. There are five types of WBC which are
Monocyte, Lymphocyte, Neutrophil, Basophil, and
Eusinophil. Each component in the blood cells plays their
own role in maintaining living activities and health. The
number of each element plays important role to ensure
healthiness. Lack or extreme amount of blood cells, and the
shape of RBC‘s in the body can cause disease such as
leukemia or anemia, and other medical problem. WBCs
number is important to conclude human‘s health state. This
is due to the number or quantity of this cell determined the
individual health condition and indicates diseases which
might occur. WBCs involve directly in human body defend
system. Knowledge on typical range of WBC counts in
Afro-Caribbean adults will be immediate clinical value to
physician and the WBC counts in Jamaicans are comparable
to those African origin. There are several ecological factors
that affect the result obtained which are widespread
infections, migrant populations living in the developed
countries, and social factor. Therefore, orientation value of
WBC must be obtained from their native habitat population
for accurate analysis in cell counting. Blood cells sample

images taking from microscopic can be analyzed to count
the number of target cells by manual counting and automatic
counting. Manual counting can be very detail but might not
accurate due to human error. Meanwhile, computerized
technique using software was developed to improve the
quality of analysis. However, some problem might occur
when system failed to count WBC number precisely due to
cell overlapping with other cells. This is due to the
technique used was based on the cell size and shape.
Incomplete shape of cell in image also will cause problem to
count the cell accurately. Research need to be done to
overcome the problem by using other technique, or
improving existing technique.
B. PREVIOUS FINDINGS FOR BLOOD RELATED
DISEASES
From the clarification on pathology of blood cells, especially
on WBC, it can be said that normal quantity of WBC is
important to ensure person healthiness. Normal number of
WBC in average human adult was about 7000/micro liter,
about 1% of total blood cell in the body. Increase in the
number of WBC in the body was called leukocytosis,
while decrease in the number of WBC was called
leucopenia. Leukocytosis was most likely to occur
compared to leucopenia. The example of leukocytosis was
shown in fig(1), when excessive amount of WBC is
recognized in a sample of microscopic blood image.
The dark blue cells indicate WBC‘s, while light blue
indicates RBC‘s. From the image, it shows that WBC‘s
number was high or most likely same as the number of
RBC‘s. Meanwhile, the comparison between normal WBC
quantity and abnormal WBC numbers can be seen through
fig (2).

C. PROPOSED METHOD
The method mentioned in this paper for WBC extraction
and counting is Color based clustering method by
focusing on image intensity level. There are several steps
needed to be done in this method to get the desired
result. fig (3) shows the block diagram of flow
processes involved in this research. It shows that this
research and study is started by importing the input
image into MATLAB workspace (m-file). Then, the
image will be transformed into grayscale image by using
specific function called grayscale conversion.
Then, the grayscale image undergoes next process by
using different techniques and functions for further
analysis. Meanwhile, for WBC extraction and counting,
it only needs contrast adjustment and function for
counting the number of WBC by referring to the number
of boundaries detected. Below figure shows the flow of
the process:
The steps involved in the processing of images are as below:
Steps for clustering
1.Read the image.
2.Convert image from rgb to lab color space.
3.Combine a&b color space i.e both the color axis while

E. RESULTS & CONCLUSIONS
With the implementation of proposed method, we get the
results which calculates the minimum number of pixels
detected because there can be huge no. of RBCs, fluid and
WBCs and the percentage of RBCs & fluid in the complete
cell would be more than the WBCs in the image. So, when
calculating the cancerous area, it would be the minimum of
the overall area covered by colored pixels. The proposed
method can be very helpful in diagnosing the blood cancer at
early stage. This method is generalized to detect cancer at
initial stage wherein cancerous cells would be lesser. So,
here we conclude the results achieved:
1. Number of cells counted manually are same in some of
the case because the images are clear and the cells are
prominent in size to be captured by human eyes.
2. Number of cells are not same in some of the case where
the images do not have WBCs defined in prominent size.
They cannot be detected and extracted through naked eyes.
Hence, the one detected by color based clustering are actual
count of WBC Cells.
