Multimodal Medical Image Fusion Based On SVDIOSR Journals
Image fusion is a promising process in the field of medical image processing, the idea behind is to
improve the content of medical image by combining two or more multimodal medical images. In this paper a
novel fusion framework based on singular value decomposition - based image fusion algorithm is proposed.
SVD is an image adaptive transform, it transforms the matrix of the given image into product USVT
, which
allows to refactor a digital image into three matrices called tensors. The proposed algorithm picks out
informative image patches of source images to constitute the fused image by processing the divided subtensors
rather than the whole tensor and a novel sigmoid-function-like coefficient-combining scheme is applied to
construct the fused result. Experimental results show that the proposed algorithm is an alternative image fusion
approach.
A Survey on Segmentation Techniques Used For Brain Tumor DetectionEditor IJMTER
In recent years Brain tumor is one of the most commonly found causes for death among
children and adults. Early detection of tumor is a must in order to reduce the death rate. For tumor
detection various image techniques can be used. In this paper we mainly concentrate on the images
obtained from MRI scans. In MRI images, the tumor may appear clearly, but for further treatment
the physician need to be a qualified and well experienced person. In order to help the radiologist in
detection computer-aided diagnosis was developed. The generation of a CAD system consists of
several processes and among them segmentation is considered to the most important process. Image
Segmentation is a process of partitioning an image into multiple segments. The main objective of
segmentation is to represent the image into a simplified form so as to increase the efficiency and
accuracy of the system. Therefore the segmentation of brain tumor can be considered as an important
role in the medical image process. Hence in this paper we concentrate on the recently used
segmentation techniques for the detection of tumor using MRI images.
AN AUTOMATIC SCREENING METHOD TO DETECT OPTIC DISC IN THE RETINAijait
The location of Optic Disc (OD) is of critical importance in retinal image analysis. This research paper carries out a new automated methodology to detect the optic disc (OD) in retinal images. OD detection helps the ophthalmologists to find whether the patient is affected by diabetic retinopathy or not. The proposed technique is to use line operator which gives higher percentage of detection than the already existing methods. The purpose of this project is to automatically detect the position of the OD in digital retinal fundus images. The method starts with converting the RGB image input into its LAB component. This image is smoothed using bilateral smoothing filter. Further, filtering is carried out using line operator. After which gray orientation and binary map orientation is carried out and then with the use of the resulting maximum image variation the area of the presence of the OD is found. The portions other
than OD are blurred using 2D circular convolution. On applying mathematical steps like peak classification, concentric circles design and image difference calculation, OD is detected. The proposed method was evaluated using a subset of the STARE project’s dataset and the success percentage was found
to be 96%.

Interactive liver tumor segmentation using eSAT Journals
Abstract This literature review attempts to provide a brief overview of the most common segmentation techniques, and a comparison between them. It discusses the “Grab-Cut” technique, and" Graph Cut" techniques. GrabCut is a way to perform 2D segmentation in an image that is very user friendly. The user only need to input a very rough segmentation between foreground and background .The Graph Cut approaches to segmentation can be extended to 3-D data and can be used for segmenting 3-D volumes. Other segmentation techniques use either contour or edge segmentation to perform segmentation. The Graph Cut techniques use both contour and edge detection. Typically this is down by drawing a rectangle around the object of interest. The way that this is accomplished technically is by using a combination of Graph Cuts and statistical models of the foreground and background structure in the colour space. Grab Cut Technique use very minimum energy to separate Foreground and Background Images. Keywords - Interactive Image Segmentation, Object Selection, Foreground extraction, Graph Cut, Grab cut

Abstract: These days analysing patient data in the form of medical images to perform diagnose while doing detection
and prediction of a disease has emerged as a biggest research challenge. All these medical images can be in the form of
X-RAY, CT scan, MRI, PET and SPECT. These images carry minute information about heart, brain, nerves etc within
themselves. It may happen that these images get corrupted due to noise while capturing them. This makes the complete
image interpretation process very difficult and inaccurate. It has been found that the accuracy rate of existing method is
very less so improvement is required to make them more accurate. This paper proposes a Machine Learning Model based
on Convolutional Neural Network (CNN) that will contain all the filters required to de-noise MRI or USI Images. This
model will have same error rate efficiency like those of data mining techniques which radiologists were interested in. The
filters used in the proposed work are namely Weiner Filter, Gaussian Filter, Median Filter that are capable of removing
most common noises such as Salt and Pepper, Poisson, Speckle, Blurred, Gaussian existing in MRI images in Grey Scale
and RGB Scale.

AN EFFICIENT WAVELET BASED FEATURE REDUCTION AND CLASSIFICATION TECHNIQUE FOR...ijcseit
This research paper proposes an improved feature reduction and classification technique to identify mild and severe dementia from brain MRI data. The manual interpretation of changes in brain volume based on visual examination by radiologist or a physician may lead to missing diagnosis when a large number of MRIs are analyzed. To avoid the human error, an automated intelligent classification system is proposed
which caters the need for classification of brain MRI after identifying abnormal MRI volume, for the diagnosis of dementia. In this research work, advanced classification techniques using Support Vector Machines based on Particle Swarm Optimisation and Genetic algorithm are compared. Feature reduction
by wavelets and PCA are analysed. From this analysis, it is observed that the proposed classification of SVM based PSO is found to be efficient than SVM trained with GA and wavelet based feature reduction technique yields better results than PCA.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Abstract
In the previous paper the medical images detect the edges and boundaries using various edge detection
algorithms. Several disadvantages to apply edge detection in medical image such as noise sensitivity, inaccurate
does not responding to some of edges and major drawbacks (i) complicated (ii)complex computations. But in
proposed systemising watershed algorithm to detect the boundaries and edges in medical images. There is
internal and external markers and its has global thresholding, region merging and splitting or watershed
transform.
Keywords: Image, Image Segmentation, Edge detection algorthims, Watershed algorithm.

INTRODUCTION
Image
A digital image is represents a twodimensional image. It is a finite set of digital values
and referred as picture elements or pixels.
Pixels
Pixel values typically classify into gray
levels, colours, heights, opacities etc.
Common image formats include
– 1 sample per point (B&W or Grayscale)
– 3 samples per point (Red, Green, and Blue)
– 4 samples per point (Red, Green, Blue, and
“Alpha”, a.k.a. Opacity)
1.1 IMAGE SEGMENTATION
Image segmentation is a process of a
image(digital) into multiple segments.
It’s represent set of pixels and also known as
superpixels.
Image segmentation is used to locate
boundaries and objects (curves, lines, etc.) in images.
The image segmentation is partition an image
into meaningful regions with respect to a
particular application
The segmentation is measured from the image
that represents greylevel, colour, texture, depth or
motion.
Image segmentation classify into three stages:
a) Greyscale
b) Texture
c) Motion
1.2. EDGE DETECTION ALGORITHM
It to identifying points in a digital image at
which the image brightness and changes sharply.

TYPES OF EDGE DETECTION
ALGORITHM
2.1 SOBEL
: The Sobel operator performs a 2-D
spatial gradient measurement on an image and so
emphasizes regions of high spatial frequency that
correspond to edges.
2.2 PREWITT : The prewitt edge detector is an
accurate way to approximation the magnitude and
orientation of an edge.
2.3 CANNY : The Canny algorithm can be used an
optimal edge detector based on a set of criteria which
include finding the most edges by minimizing the
error rate, marking edges as closely as possible to the
actual edges to maximize localization, and marking
edges only once when a single edge exists for
minimal response.
2.4. Common disadvantage of edge detection
algorithms
Sensitivity to noise,
Inaccurate responding to some of the existing
edges.
Malfunctioning at corners, curves and where the
gray level intensity function varies.
It not finding the orientation of edge because of
using the Laplacian filter Colour Edge
Detectors: Complicated, Complex Computations
2.5 Image segmentation based watershed
1. Use internal markers to watershed lines of the
gradient of image to be segmented.
2. Use watershed lines as external markers
3. Each region defined by the external markers
contains a single internal marker and part of the
background
4. The solution is reduced to partitioning each
region into two parts: object (it containing
internal markers) and a single background (it
containing external markers)
–
Region growing, global thresholding,region
merging and region splitting, or watershed
transform.

the employee. However, workplaces can help
employees to perform these tasks safely and easily by
implementing and maintenance proper policies and
procedures. The lumbar region which is most one of
the important parts in the spine has played a vital role
in the researches. The anatomy of lumbar region, the
lumbar spine, the back pain and their relationship are
put together in literature. The finite element analysis
in the field of orthopaedics for the lumbar region has
also been explained with its uses. The evaluation and
management of occupational low back disorders and
back pains were studied. The movement of human by
motor control and biomechanics are explained in
various aspects. Such similar investigations are made
on the spine disk and reported. Till date, the motion
segment of the spine consists of two parts of which
one is a vertebrae and the other one a disc.To
explicate proper information from the images, a
fundamental tool used is the Edge detection
technology. This provides the outlines of an image
and boundaries.This also proves as a tool to remove
the noises in the images to enhance the appearance.
To detect the correct boundary in a noisy image is
still difficult. Based on the evaluation the watershed
algorithm is used to detect the boundaries of spine
disc image from the noisy CT scanned image produce
a better result. The vertebral body of each lumbar
vertebra is large, wider from side to side than from
front to back, and a little thicker in front than in back.
It is flattened or slightly concave above and below,
concave behind, and deeply constricted in front and at
the sides.

3.1 Watershed introduction
Watershed transform proposed by Digabel
and Lantu_ejoul and improved by Beucher and
Lantu_ejoul
is the method used for image
segmentation. In this section we introduce de_nitions
of the watershed transform, it explain about the
generalization of the skeleton by inuence zones
(SKIZ) to grey value images.
The key functions of the Human spine as a
composite structure is to protect the spinal cord.

RESULTS AND DISCUSSION
To further evaluate the efficiency of the
proposed method in addition to the visual inspection,
the proposed boundary detection method numerically
