00:00 - 00:03
I'm here to present to my final thesis which is
00:03 - 00:06
based on a comparative study to classify the denomination and
00:06 - 00:08
detection counterfeit of indian magnets.
00:09 - 00:12
So with no further delay, let's start with the presentation.
00:13 - 00:17
I would remove my uh huh better front background and
00:17 - 00:18
you have to move into the presentation.
00:20 - 00:25
So my presentation consists of seven slides, seven sections.
00:26 - 00:30
Introduction, problem statement aims and objectives, literature, review, research methodology,
00:30 - 00:32
analysis and discussion, conclusion and recommendation.
00:33 - 00:35
Yeah. Let's move ahead.
00:36 - 00:36
So an introduction.
00:37 - 00:39
The moment organizations plays a crucial part.
00:40 - 00:44
Gas transaction can easily be a victim of their currency.
00:46 - 00:48
Annual report in 2018 says that in India it's a
00:48 - 00:50
big concern fake news of a big concern.
00:50 - 00:52
There has been around 5 22,000 and 8 to 300
00:53 - 00:54
ft notes which are available in the market.
00:55 - 01:00
We need to stop this and to stop illegal business
01:00 - 01:01
activities and economical terrorism.
01:03 - 01:05
What is if I see and so if I see
01:06 - 01:09
any is fake indian currency note, which is usually used
01:10 - 01:12
by the National Crime Records Bureau in India and the
01:13 - 01:14
media to address fake notes.
01:17 - 01:21
Uh, so how can machine learning help us uh to
01:21 - 01:22
identify fake notes?
01:22 - 01:26
So advancement in machine learning has been created.
01:27 - 01:31
Uh, the image recognition especially they're really cost effective, accurate
01:31 - 01:33
systems and portable and easy to use.
01:34 - 01:38
Uh, so we're here, we're also planning or aiming to
01:38 - 01:40
create a cost effective and efficient way of identifying.
01:40 - 01:46
Banknotes are using deep learning and image recognition techniques related
01:46 - 01:50
works. So most of the related works were based on
01:50 - 01:54
optical or electrical sensors, uh focusing on the inbuilt photos
01:55 - 01:58
instead of holographic features of the notes are based on
01:58 - 02:01
images or visual attributes which are classified to accept features.
02:01 - 02:04
This is mostly used in deep learning and machine learning
02:04 - 02:09
techniques. Let's go through some examples of previous papers or
02:09 - 02:13
study by military dancing, which was focused on Canaan for
02:14 - 02:16
classification and S.
02:16 - 02:16
V. M.
02:17 - 02:18
Of a classification and H.
02:18 - 02:18
O. G.
02:19 - 02:23
Was used for image feature extraction, which was around 90%
02:24 - 02:27
accurate. Then there was another study where serena nadine in
02:28 - 02:31
which a hybrid model was used using ocr simple face
02:31 - 02:35
recognition model and half transformation for ultraviolet clients detection.
02:36 - 02:37
It was around 93% effective.
02:38 - 02:41
Then there was another study by roger in which metal
02:41 - 02:42
and Canaan techniques were used.
02:43 - 02:47
Uh These images were cropped segmented and the intensity of
02:47 - 02:49
the features are being used for the detection of fake
02:50 - 02:52
notes. What are the problems with these studies?
02:52 - 02:55
The limitations that were generally noticed were uh they were
02:56 - 03:01
really gen rick uh for all the denominations uh limited
03:01 - 03:06
studies on more updated and efficiency nN models uh Color
03:06 - 03:09
spaces were not really experimented with.
03:10 - 03:13
All invalid notes were not considered because they can also
03:15 - 03:18
be part of fake notes are a problem for visually
03:19 - 03:24
impaired. What makes this tastes different?
03:25 - 03:27
So for these species, we have considered all the denominations.
03:28 - 03:31
Uh Different color spaces have also been taken into account
03:32 - 03:34
both handcrafted and techniques.
03:35 - 03:39
Both hand capture techniques and CNN techniques were used uh
03:40 - 03:40
for classification.
03:44 - 03:46
What is the aim and objective to create a system
03:46 - 03:51
that is accurate uh able to successfully classify denominations and
03:51 - 03:52
identify fake notes.
03:54 - 03:55
Outline of the objectives.
03:56 - 03:59
To use a traditional and modern machine learning techniques to
03:59 - 04:03
use hand crafted and also deploying techniques to extract features
04:04 - 04:06
to do a comparative study of the models they can
04:06 - 04:10
in SPM and CNN uh and then suggest the most
04:10 - 04:12
appropriate and optimized approach.
04:14 - 04:18
Uh significance and scope, contribution to successful bank no detection,
04:19 - 04:23
uh including comparative study, which can be later used uh
04:23 - 04:32
for further improvement Literature review in 2016, New currencies were
04:32 - 04:35
introduced and the whole currencies, all denominations of 500 and
04:36 - 04:37
100 Anna were not legal anymore.
04:39 - 04:42
So modern image recognition can make use of this newly
04:43 - 04:48
visually different banknotes introduced for fake node dissection.
04:51 - 04:53
Let's discuss some of the security features in the new
04:53 - 05:00
banknotes security thread, there's a watermark micro lettering latin image
05:00 - 05:02
portrait of Mahatma Gandhi which are also there previously.
05:03 - 05:07
Then they're bleed lines and then see to register optically
05:07 - 05:12
variable ink and a panel guarantee close Here are two
05:12 - 05:16
images of Iron Ore 500 showing the features of the
05:17 - 05:17
new banknotes.
05:19 - 05:19
All right.
05:20 - 05:24
So how image recognition is done using neural networks.
05:25 - 05:29
So neuron, it was basically replicates or try to replicate
05:29 - 05:32
human brain, how it works or is being inspired by
05:32 - 05:37
it. Uh So it has been used to successfully to
05:37 - 05:41
attain a lot of complex activities like speech recognition image
05:41 - 05:45
processing. There are also successful implementation in the healthcare industry
05:46 - 05:51
for complex structure analysis has been also used to develop
05:52 - 05:54
intelligent traffic system and there are a lot of other
05:55 - 05:55
examples like this.
05:57 - 06:00
So what are the techniques that are being used here?
06:00 - 06:03
We have used a Canon model can and model is
06:03 - 06:08
to kenya's algorithm which is basically focused on the distance
06:09 - 06:13
of the data points and classify the images based on
06:14 - 06:15
the features which are closest to it.
06:16 - 06:22
It's it's a very, quite popular um algorithm for classification.
06:23 - 06:24
Then there is S.
06:24 - 06:25
V. M.
06:25 - 06:25
S. V.
06:26 - 06:27
M belongs to linear machine learning models.
06:28 - 06:34
They are extremely efficient, extremely accurate, Especially good when there
06:34 - 06:41
are only two groups for classification, then there is of
06:41 - 06:45
course the neural networks, uh, neural networks are extremely advanced,
06:46 - 06:46
they're really efficient.
06:47 - 06:53
Uh They have this tendency to improve their performance with
06:54 - 06:55
more and more training.
06:56 - 07:03
And it is, it's so it's quite advanced than usually,
07:04 - 07:07
uh more advanced in the traditional machine learning algorithms.
07:10 - 07:14
Uh, so for testing uh, train split, we are used
07:15 - 07:19
to cross validation, especially the careful cross validation over here.
07:19 - 07:22
Cross validation help in eliminating under fitting and overfitting problems.
07:22 - 07:24
Um Kay fooled.
07:24 - 07:28
Cross validation is especially helpful when the number of data
07:29 - 07:29
sets are really limited.
07:30 - 07:34
Mm And there is also a ah class imbalance in
07:34 - 07:38
which case we use stratification or stratified, careful cross validation.
07:41 - 07:42
Let's move into research methodology.
07:43 - 07:46
So over here, the system is that working on images
07:46 - 07:49
of indian magnets for verification and classification.
07:50 - 07:52
Uh, We have considered both front and rear view of
07:53 - 07:54
the banknotes.
07:55 - 07:58
So, and we have included both modern and all magnets
07:59 - 07:59
that are currently in use.
08:03 - 08:07
So let's look at the workflow utilization of button both
08:07 - 08:09
front and back view of images.
08:09 - 08:13
Uh, Traditional machine learning algorithms has mused again.
08:13 - 08:13
NNS VM.
08:14 - 08:16
Also CNN uh neural networking has been used.
08:17 - 08:17
H. I.
08:17 - 08:21
G. Has been used for uh feature extraction in hand
08:21 - 08:21
grocery techniques.
08:22 - 08:23
Are we able to use the modern C.
08:24 - 08:25
And techniques for feature extraction?
08:26 - 08:30
Um Kay fold, stratified, careful cross validation has been used
08:30 - 08:34
for testing and split a sudden evaluation metrics have been
08:35 - 08:38
taken into consideration like area, under curve classification, accuracy, scoring
08:39 - 08:43
position. School different colours, species had also been accounted for.
08:44 - 08:45
This is basically the workflow.
08:46 - 08:47
The data moves into the pre processing state.
08:48 - 08:51
Uh It's processed and feature extraction is done.
08:51 - 08:55
Classification model classified into different denomination, invest on the denomination
08:56 - 09:01
denomination. It is uh fetch to that particular flow where
09:01 - 09:02
the features are getting extracted.
09:03 - 09:07
We referred to that classification model and then authentication is
09:07 - 09:15
done. The data sets includes both self taken and images
09:16 - 09:16
which are available online.
09:17 - 09:22
Uh It included different images with different backgrounds and different
09:23 - 09:23
lighting conditions.
09:27 - 09:32
Pre processing was stunned where it was passed through a
09:32 - 09:36
caution filter to remove noise and smoothing was done.
09:37 - 09:40
Then they were transformed into two separate color spaces.
09:40 - 09:42
RGB NLB uh to compare the performances.
09:43 - 09:46
Feature extraction was done during one of the handcrafted techniques
09:47 - 09:47
of H O.
09:47 - 09:50
G. And then a neural net was like VG 19
09:51 - 09:51
and squeezed.
09:51 - 09:59
It train interests split was done using stratified, careful cross
09:59 - 10:01
validation technique as discussed.
10:02 - 10:07
Earlier evolution metrics included a UCC F on precision and
10:08 - 10:11
recall a from school and recalled school were given the
10:11 - 10:13
highest priority order based on the requirement.
10:17 - 10:20
Let's look into the work floor so the images through
10:21 - 10:23
data preparation, flu then data pre processing.
10:23 - 10:24
The middle was transformed.
10:24 - 10:27
Feature was extracted, shouldn't desperate was done.
10:28 - 10:30
And then it was fed to the classification models.
10:31 - 10:32
All the NATO was classified.
10:33 - 10:34
And then we did the performance evaluation.
10:36 - 10:36
Uh huh.
10:39 - 10:45
So data filtering was done using Goshen filter remove noise.
10:45 - 10:50
Is this is a picture of a lab color transformed
10:51 - 10:52
image of the note.
10:57 - 11:00
And then we moved into feature extraction in the first
11:00 - 11:02
phase, the north for classified into different denominations.
11:03 - 11:07
Uh and then uh feature was extracted and then fed
11:07 - 11:10
to a different classifies of KMs human.
11:10 - 11:15
And um ah then in the second phase After the
11:15 - 11:20
denomination was considered uh then it features were extracted using
11:20 - 11:22
squeeze net and GT 19 and Hawk feature.
11:23 - 11:27
Um The features are extracted for both RGB NLB transformed
11:28 - 11:32
images and then for two networks classifies like ken and
11:32 - 11:36
feminine. And uh let's look at the training workflows.
11:37 - 11:41
Both kind of transformed images like RGB NLB affair to
11:41 - 11:45
feature extraction, which is done using hog 19, squeezing it
11:45 - 11:47
and then train desperate was done and then fit models
11:48 - 11:50
again and spm and neural networks and then model liberation
11:50 - 11:52
was done on them Discussion.
11:53 - 11:58
Okay, so for classification of notes and it was performed
11:58 - 11:59
the best with an F one score of 0.907.
12:01 - 12:04
Uh For classification of, not based on authenticity is being
12:04 - 12:05
performed the best.
12:05 - 12:10
Um When the model was trained on RGB images, squids
12:11 - 12:18
net uh was performing better for seeing model extraction and
12:19 - 12:20
it was not the best in the outcome, but the
12:20 - 12:21
performance was consistent.
12:22 - 12:26
CNN uh Squeezing it improved the performance because it was
12:26 - 12:29
faster and more efficient and which is 19 and CNN
12:29 - 12:33
techniques took longer than handcrafted techniques.
12:34 - 12:39
Uh but they were much more accurate and performed better
12:39 - 12:43
than H O G mhm extraction technique.
12:43 - 12:44
and it takes a longer time level.
12:44 - 12:45
Of course within.
12:46 - 12:49
It needs more consistent and takes a fraction of time.
12:50 - 12:52
More. Rgb color space proved to be more effective.
12:52 - 12:55
Which was really surprising because early because of space to
12:55 - 13:00
considered very close to humanize perception uh turned out to
13:00 - 13:00
be less effective.
13:02 - 13:08
So conclusion recommend recommended to use quiz net for image
13:08 - 13:09
and merging and invest.
13:09 - 13:11
Model can be used to classify the north based on
13:11 - 13:13
denominations. After determining the denominations.
13:14 - 13:16
Those can be fed to an SV model to detect
13:16 - 13:16
its authenticity.
13:18 - 13:20
For emails, denomination is the model should be trained for
13:20 - 13:21
detection of technique.
13:22 - 13:26
Notes specific is via model increases the accuracy and effectiveness
13:27 - 13:30
of the model dramatically specific when it is specific to
13:30 - 13:33
denominations rather than generate models.
13:35 - 13:37
Uh So what are the future recommendation in future?
13:38 - 13:38
A system?
13:39 - 13:42
We recommend to create a system that can detect multiple
13:42 - 13:45
notes of different denominations in a single scene and calculate
13:45 - 13:46
the total valuation.
13:46 - 13:49
That will be really good and helpful in real life.
13:50 - 13:53
Uh Then we can also enhance the present study through
13:53 - 13:57
various augmentation techniques applied on the images, like for example,
13:58 - 14:02
cropping them and the object and eviction cropping it and
14:02 - 14:03
changing its orientation.
14:05 - 14:08
And then individual feature detection counters for security features to
14:08 - 14:09
check authenticity of the notes.
14:10 - 14:14
Um This can prove to be much more efficient and
14:14 - 14:14
much more accurate.
14:16 - 14:18
Ah So that's it from a presentation.
14:19 - 14:21
Uh It was a pleasure.
14:22 - 14:23
Thank you.
14:24 - 14:24
Have a nice day.
