A NOVEL APPROACH FOR SEGMENTATION OF SECTOR SCAN SONAR IMAGES USING ADAPTIVE ...ijistjournal
The SAR and SAS images are perturbed by a multiplicative noise called speckle, due to the coherent nature of the scattering phenomenon. If the background of an image is uneven, the fixed thresholding technique is not suitable to segment an image using adaptive thresholding method. In this paper a new Adaptive thresholding method is proposed to reduce the speckle noise, preserving the structural features and textural information of Sector Scan SONAR (Sound Navigation and Ranging) images. Due to the massive proliferation of SONAR images, the proposed method is very appealing in under water environment applications. In fact it is a pre- treatment required in any SONAR images analysis system. The results obtained from the proposed method were compared quantitatively and qualitatively with the results obtained from the other speckle reduction techniques and demonstrate its higher performance for speckle reduction in the SONAR images.

An efficient method for recognizing the low quality fingerprint verification ...IJCI JOURNAL
In this paper, we propose an efficient method to provide personal identification using fingerprint to get better accuracy even in noisy condition. The fingerprint matching based on the number of corresponding minutia pairings, has been in use for a long time, which is not very efficient for recognizing the low quality fingerprints. To overcome this problem, correlation technique is used. The correlation-based fingerprint verification system is capable of dealing with low quality images from which no minutiae can be extracted reliably and with fingerprints that suffer from non-uniform shape distortions, also in case of damaged and partial images. Orientation Field Methodology (OFM) has been used as a preprocessing module, and it converts the images into a field pattern based on the direction of the ridges, loops and bifurcations in the image of a fingerprint. The input image is then Cross Correlated (CC) with all the images in the cluster and the highest correlated image is taken as the output. The result gives a good recognition rate, as the proposed scheme uses Cross Correlation of Field Orientation (CCFO = OFM + CC) for fingerprint identification.

COLOUR BASED IMAGE SEGMENTATION USING HYBRID KMEANS WITH WATERSHED SEGMENTATIONIAEME Publication
Image processing, arbitrarily manipulating an image to achieve an aesthetic standard or to support a preferred reality. The objective of segmentation is partitioning an image into distinct regions containing each pixels with similar attributes. Image segmentation can be done using thresholding, color space segmentation, k-means clustering.
Segmentation is the low-level operation concerned with partitioning images by determining disjoint and homogeneous regions or, equivalently, by finding edges or boundaries. The homogeneous regions, or the edges, are supposed to correspond, actual objects, or parts of them, within the images. Thus, in a large number of applications in image processing and computer vision, segmentation plays a fundamental role as the first step before applying to images higher-level operations such as recognition, semantic interpretation, and representation. Until very recently, attention has been focused on segmentation of gray-level images since these have been the only kind of visual information that acquisition devices were able to take the computer resources to handle. Nowadays, color image has definitely displaced monochromatic information and computation power is no longer a limitation in processing large volumes of data. In this paper proposed hybrid k-means with watershed segmentation algorithm is used segment the images. Filtering techniques is used as noise filtration method to improve the results and PSNR, MSE performance parameters has been calculated and shows the level of accuracy
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.

Edge detection of herbal plants is a set of mathematical methods which aim at identifying points in a digital image at which the image brightness changes sharply and has discontinuities. They are defined as the set of curved line segments termed edges. Effective edge detection for microscopic image of herbal plant is proposed through this paper which compares the edge detected images and then performs further segmentation. Comparison between Sobel operator, Prewitt, Canny and Robert cross operators is performed. Our method after efficient edge detection performs Gabor filter and K-means clustering to procure a better image. It is then subjected to further segmentation. Experimental methods in our proposed algorithm show that our method achieves a better edge detection as compared to other edge detector operators.

DIGITAL RESTORATION OF TORN FILMS USING FILTERING T ECHNIQUESAM Publications
The acceptance of digital imaging is motivating many photography enthusiasts to transfer their
photographic archive to digital form. Scans of negatives and positives are preferred to be scanned at high resolution
which makes small cracks and scratches very apparent. These unsightly defects have become an important issue
for consumers. Filtering techniques are used for the restoration process which is fully automatic whereas the existing
systems were semi-automatic or completely manual. The method used for the detection of tear is dilation process and
top-hat transform. Top-hat transform might misinterpret dark brush strokes as cracks. In order to avoid these
unwanted alterations to the original image, brush strokes are separated from the actual cracks using clustering
technique. Tear removal includes order statistics filtering which deals with the reconstruction of missing or
damaged image areas.

An Efficient Image Denoising Approach for the Recovery of Impulse NoisejournalBEEI
Image noise is one of the key issues in image processing applications today. The noise will affect the quality of the image and thus degrades the actual information of the image. Visual quality is the prerequisite for many imagery applications such as remote sensing. In recent years, the significance of noise assessment and the recovery of noisy images are increasing. The impulse noise is characterized by replacing a portion of an image’s pixel values with random values Such noise can be introduced due to transmission errors. Accordingly, this paper focuses on the effect of visual quality of the image due to impulse noise during the transmission of images. In this paper, a hybrid statistical noise suppression technique has been developed for improving the quality of the impulse noisy color images. We further proved the performance of the proposed image enhancement scheme using the advanced performance metrics.

Short term Multi Chain Hydrothermal Scheduling Using Modified Gravitational S...IJARTES
This paper proposes the modified Gravitational
search algorithm (GSA) to solve short term multi chain
hydrothermal scheduling problem while satisfying all
operational and physical constraints. The effect of the valve
point loading has been considered. Gravitational search
algorithm is based on the Newton’s law of gravitation. All
objects attract each other and global movement is towards
the heavier masses .However GSA has certain randomness
in search direction resulting in the weak local search ability.
In modified GSA, a time varying maximum velocity equation
is used which controls the exploration and improves the
convergence rate which strengthens its local search ability
and the quality of the hydrothermal solution.

Integrated Air Conditioning Unit for AutomobilesIJARTES
Integrated Air Conditioning Unit for
Automobiles
In this paper, the investigation was made for the utilization
of waste heat in an improvised manner, so that the total
power of the automobile is not going to change and the fuel
efficiency is going to be enhanced. Here the use of vapor
absorption refrigeration system for the air conditioning
system was proposed and analyzed. This system was taken as
it can run on very low grade energy, such as waste heat of
the exhaust gas. The recent trend is to use the vapor
compression refrigeration system, where the principal part is
the compressor, which takes the power from the engine or
from auxiliary power unit and hence the fuel consumption
rate is increased. In the recent global scenario reducing the
fuel consumption is the main research area. The cooling
load of the automobile is estimated about 1.37 TR and the
measured cop value for the proposed model is varied from
0.85 to 1.04.
Here the main problem definition is to design an air
conditioning system which runs on exhaust gas waste heat
by exchanging with the refrigerant R134-a inside a
generator which is the replacement of the compressor in a
vapor absorption refrigeration system. The calculation
related to the design of proposed shell and tube heat
exchanger i.e. the generator for the model is carried out and
the rest design is theoretical study and proposed model to be
implemented in large scale after prototype model testing.

Ijartes v2-i1-001Evaluation of Changeability Indicator in Component Based Sof...IJARTES
The maintaining of software system is a major
cost concern. The maintaining of a software system depends
on how the changes made to it. The maintainability of a system
depending on the folw of software, its design pattern and
CBSS. In Maintainability phase of a sotware system there are
4 parts, like analyzing, testing, stability, and changes made to
it. In some side areas, these systems emerged very rapidly.
There are many companies which purchase software instead
of developing it .These companies do not have any interst in
the testing of the system but wants to like smoothness in the
flow of the system during changes.
Changeability is one of the characteristics of maintainability.
Software changeability is associated with refactoring which
makes code simpler and easier to maintain (enable all
programmers to improve their code).Factors that affect
changeability include coupling between the modules, lack of
code comments, naming of functions and variables.
Basically,”changeabilty” is the ability of a product or software
to be able to change the structure of the program. It is the rate
the product allows the modification to its components.
In this paper changeability based cost estimation is done.
Initially we take four components; these components are
evaluated based on the coupling, cohesion and Interface
metrix. Next some changes are made to the existing
components and than again these components are evaluated.
Now, on the basis of these two evaluations some conclusion is
made for changeability cost.

Adaptive Source Provision System (ASPS) for
Proficient Freight Complementary in WiMAX
Network
Today in the wireless network field, WiMAX
(Worldwide Interoperability for Microwave access) has
emerged out as one of the promising networking
technologies. In order to compete with the existing wireless
technologies like Wi-Fi and Bluetooth (IEEE 802.15),
WiMAX has to promise cost efficiency and better quality of
service (QoS). The Adaptive source provision system is
proposed to control traffic rate and ensure load balancing in
the WiMAX network. The proposed approach considers
relay station in the network. When there is an arrival of new
users in the network, its data rate is computed and then
compared with the data rate of RS. When the data rate of
new user is less than that of RS, then the data rate of the
corresponding base station is compared. The connections
are switched from congested stations to non-congested
stations to minimize network load. The handover mechanism
is used by BSs for optimally balancing the traffic load within
the network. LB-based handover mechanism guarantee
user’s QoS and evenly distributes the traffic load. The
experimental analysis showed that the proposed method
achieves better traffic management and load balancing
when compared with the existing approaches.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
