Role of fuzzy in multimodal biometrics systemKishor Singh
Person identification is possible through the biometrics using their physiological and behavioral characteristics such
as face, ear, thumb print, voice, signature and key stock. Unimodal biometric systems face a range of problems, including noisy
data, intra-class versions, small liberty, non-university, spoof assaults, and unsustainable error rates. Some of these drawbacks
can be overcome by multimodal biometric technologies, which incorporate data from various information sources. In this paper
we work on multimodal biometric using three modalities face, ear and foot to find the optimal results using fuzzy fusion
mechanism and produces final identification decision via a fuzzy rules that enhance the quality of multimodalities biometric

Robust Analysis of Multibiometric Fusion Versus Ensemble Learning Schemes: A ...CSCJournals
Identification of person using multiple biometric is very common approach used in existing user
validation of systems. Most of multibiometric system depends on fusion schemes, as much of the
fusion techniques have shown promising results in literature, due to the fact of combining multiple
biometric modalities with suitable fusion schemes. However, similar type of practices are found in
ensemble of classifiers, which increases the classification accuracy while combining different
types of classifiers. In this paper, we have evaluated comparative study of traditional fusion
methods like feature level and score level fusion with the well-known ensemble methods such as
bagging and boosting. Precisely, for our frame work experimentations, we have fused face and
palmprint modalities and we have employed probability model - Naive Bayes (NB), neural
network model - Multi Layer Perceptron (MLP), supervised machine learning algorithm - Support
Vector Machine (SVM) classifiers for our experimentation. Nevertheless, machine learning
ensemble approaches namely, Boosting and Bagging are statistically well recognized. From
experimental results, in biometric fusion the traditional method, score level fusion is highly
recommended strategy than ensemble learning techniques.
In the age of Biometric Security taking over the traditional security features, this is a small intro to the Biometric features one can use to enhance the security. The various modalities have been explained.
Integrating Fusion levels for Biometric Authentication SystemIOSRJECE
— Recently a lot of works are presented in the literature for the multimodal biometric authentication. And such biometric systems have been widely accepted with increasing accuracy rates and population coverage, reducing the vulnerability to spoofing. This paper descripts about the proposed multimodal biometric system that combines the feature extraction level and the score level fusion of iris and face unimodal biometric systems in order to take advantage of both fusion techniques. The experimental results shows the performance of the multimodal and multilevel fusion techniques which are analysed using TRR and TAR to study the recognition behaviour of the approach system. From the ROC Curve plotted, the performance of the proposed system is better compared to the individual fusion techniques.
Review of Multimodal Biometrics: Applications, Challenges and Research AreasCSCJournals
Biometric systems for today’s high security applications must meet stringent performance requirements. The fusion of multiple biometrics helps to minimize the system error rates. Fusion methods include processing biometric modalities sequentially until an acceptable match is obtained. More sophisticated methods combine scores from separate classifiers for each modality. This paper is an overview of multimodal biometrics, challenges in the progress of multimodal biometrics, the main research areas and its applications to develop the security system for high security areas
Multimodal Biometrics Recognition from Facial Video via Deep Learning cscpconf
Biometrics identification using multiple modalities has attracted the attention of many
researchers as it produces more robust and trustworthy results than single modality biometrics.
In this paper, we present a novel multimodal recognition system that trains a Deep Learning
Network to automatically learn features after extracting multiple biometric modalities from a
single data source, i.e., facial video clips. Utilizing different modalities, i.e., left ear, left profile
face, frontal face, right profile face, and right ear, present in the facial video clips, we train
supervised denosing autoencoders to automatically extract robust and non-redundant features.
The automatically learned features are then used to train modality specific sparse classifiers to
perform the multimodal recognition. Experiments conducted on the constrained facial video
dataset (WVU) and the unconstrained facial video dataset (HONDA/UCSD), resulted in a
99.17% and 97.14% rank-1 recognition rates, respectively. The multimodal recognition
accuracy demonstrates the superiority and robustness of the proposed approach irrespective of
the illumination, non-planar movement, and pose variations present in the video clips.

Intelligent multimodal identification system based on local feature fusion be...nooriasukmaningtyas
Biometric identification systems, which use physical features to check a person's identity, ensure much higher security than password and number systems. Biometric features such as the face or a fingerprint can be stored on a microchip in a credit card, for example. A single modal biometric identification system fails to extract enough features for identification. Another disadvantage of using only one feature is not always readable. In this article, a smart multimodal biometric verification model for identifying and verifying a person's identity is recommended based on artificial intelligence methods. The proposed model is identified the iris and finger vein unique patterns each individual to overcome many challenges such as identity fraud, poor image quality, noise, and instability of the surrounding environment. Several experiments were performed on a dataset containing 50 people by using many matching methods. The results of the proposed model were provided a higher accuracy of 98%, with FAR and FRR of 0.0015% and 0.025%, respectively.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

3. Introduction
Unimodal biometrics has several problems such as:
Noisy data.
Intra class variation, feature sets of a same individual
Inter class similarities, feature sets belonging to
different individuals
Non universality.
Spoofing.
which cause this system less accurate and secure.
4. Multimodal biometrics systems
improve performance
A combination in a verification system
improves system accuracy
A combination in an identification system improves
system speed as well as accuracy
A combination of uncorrelated modalities (e.g. fingerprint
and face, two fingers of a person, etc.) is expected to
result in a better improvement in performance than a
combination of correlated modalities (e.g. different
fingerprint matchers)
5. When designing a multi-biometric
things must be considered:
1. The biometric features to use
2. The methods of evaluation
3. The level of fusion
4. How it will be performed, .
5. Cost
6. Operational Mode
7. Multimodal Database
7. Scenarios in a multimodal
biometric system
Multiple sensors : multiple sensors are used to sense the
same biometric identifier.
Multiple Biometrics : sense different biometric identifiers.
Multiple Units : fingerprints from two or more fingers.
Multiple Snapshots : more than one instance of the same
biometric.
Multiple Matching algorithm : combines different
representation and matching algorithms
8. Reasons to combining
(a) the ear is part of the face
(b) the ear can be acquired using the same sensor
as the face
(c) the same type of feature extraction and
matching algorithms can be used for both
9. Project Goals
To use both face and ear recognition techniques in
a single tool for enhanced security and flexibility
Compare the performance of both biometrics
Identify common sources of errors for both
techniques
10. Face Biometrics
Passive physiological method
Natural method – humans recognize people by
looking at their faces
Fast development of new algorithms
Still many unsolved problems including compensation
of illumination changes and pose invariance
Some popular methods
2D- 3D
11. EAR BIOMETRICS
Human ears have been used as major feature in the
forensic science for many years.
Ear prints found on the crime scene have been used as a
proof in over few hundreds cases in the Netherlands and
the United States.
Human ear contains large amount of specific and unique
features that allows for human identification.
Ear images can be easily taken from a distance and
without knowledge of the examined person.
Therefore suitable for security, surveillance, access
control and monitoring applications.
12. EAR BIOMETRICS
Ear does not change during human life, and face changes
more significantly with age than any other part of human
body
Colour distribution is more uniform in ear than in human
face.
Not much information is lost while working with the
greyscale or binarized images
Ear is also smaller than face , which means that it is
possible to work faster and more efficiently with the images
with the lower resolution
Ear images cannot be disturbed by glasses, beard nor
make-up. However, occlusion by hair or earrings is
possible Ear images can be easily taken from a distance
and without knowledge of the examined person
13. Implementation
Acquiring an image of the subject from
scanner/digital camera/video recording
Detect the location of any face or ear in the image
Analysis of the spatial geometry of distinguishing
features of face/ear and generate a template
Compare the template with those in the database of
known faces/ears
Declare match or mismatch depending on the
similarity and security configuration
14. Fusion
Multimodal biometric systems integrate information
presented by multiple biometric indicators. The
information can be consolidated at various levels.
Fusion is divided into three parts.
1. Fusion at the feature extraction level before matching
2. Fusion at the matching score (confidence or rank)
level.
3. Fusion at the decision (abstract label) level
15.
16. Feature Level Fusion
Combining feature vectors
Fusion at feature level is expected to provide better
recognition results but it has also observed that when
features of different modalities are compatible with each
other then fusion at feature level achieves more accuracy
17. Matching Score Level Fusion
Feature vectors are processed separately and individual matching score
is found and finally these matching scores are combined to make
classification.
One important aspect has to be addressed in the matching score level is
the normalization of scores obtained from multiple modalities
18. Decision Level Fusion
Each biometric system makes its own recognition
decision based on its own feature vector.
19. Advantages of Multi-modal Biometrics
• More accurate.
• Multibiometric systems can effectively address the problem
of noisy data.
• Multibiometric systems can be effectively used in tracking
or continuous monitoring system where only one trait is not
sufficient
• A multibiometric system may also be viewed as a
fault tolerant system.
• Multibiometric systems can offer substantial improvement
in the matching accuracy.
• Multibiometric system makes the life of any impostor
harder.
• Multibiometric systems provide better recognition
performance.
20. Disadvantages of Multi-modal
Biometrics
High cost.
High enrolment time.
High transit times.
Increase system development and complexity.
Reduced Matching Level: if a stronger biometric is used
with a weaker biometric, the result is not a stronger
combined system. The error rate of the weaker biometric
can bring down the overall effectiveness of the system
21. Conclusion
