FACE EXPRESSION IDENTIFICATION USING IMAGE FEATURE CLUSTRING AND QUERY SCHEME...Editor IJMTER
Web mining techniques are used to analyze the web page contents and usage details. Human facial
images are shared in the internet and tagged with additional information. Auto face annotation techniques are used
to annotate facial images automatically. Annotations are used in online photo search and management.
Classification techniques are used to assign the facial annotation. Supervised or semi-supervised machine learning
techniques are used to train the classification models. Facial images with labels are used in the training process.
Noisy and incomplete labels are referred as weak labels. Search-based face annotation (SBFA) is assigned by
mining weakly labeled facial images available on the World Wide Web (WWW). Unsupervised label refinement
(ULR) approach is used for refining the labels of web facial images with machine learning techniques. ULR
scheme is used to enhance the label quality using graph-based and low-rank learning approach. The training phase
is designed with facial image collection, facial feature extraction, feature indexing and label refinement learning
steps. Similar face retrieval and voting based face annotation tasks are carried out under the testing phase.
Clustering-Based Approximation (CBA) algorithm is applied to improve the scalability. Bisecting K-means
clustering based algorithm (BCBA) and divisive clustering based algorithm (DCBA) are used to group up the
facial images. Multi step Gradient Algorithm is used for label refinement process. The web face annotation scheme
is enhanced to improve the label quality with low refinement overhead. Noise reduction is method is integrated
with the label refinement process. Duplicate name removal process is integrated with the system. The indexing
scheme is enhanced with weight values for the labels. Social contextual information is used to manage the query
facial image relevancy issues.
IRJET - Visual Question Answering – Implementation using KerasIRJET Journal
This document summarizes a research paper that implements visual question answering using Keras deep learning frameworks. The researchers combine image features extracted from VGG-16 with question vectors from spaCy word embeddings to produce answers to questions about images. A multi-layer perceptron is used to merge the CNN and RNN models and produce categorical classes as answers. The implementation uses Keras with TensorFlow backend to extract image features from VGG-16 and question vectors from spaCy, which are then combined in the multi-layer perceptron to answer questions about the images.

3. 1.1. Overview
As the connectivity increasing so though the amount of data transferred is increasing, this has led to sharing
all type of data like images, voice etc. As we look at the images, we know that computer can only understand
numbers only and also as for human they might not understand all the hidden aspect of images. So to help
computers understand images the process of image segmentation was developed which is the process of
partitioning a digital image into multiple segments.
The goal of segmentation is to simplify and/or change the representation of an image into something that is
more meaningful and easier to analyze. This helps in computer in understanding the image and also help
human analyzing the images. In this one we will use two architectures of it known as Unet and mask-RCNN.

4. 1.2. Motivation
3-01-2023 Image Segmentation Using Machine Learning Department of CSE, BMSCE
With the increase of the technology and modernization, there has been increase in the data. This data contains text,
images, and many more. But as we know that computer can only understand the numbers only so understanding of
the images by the computer was a hefty thing. But with the booming of the Machine learning and deep learning
this task has become easier for computer to understand the images and even analyze and classify them.
Few of the tools and architectures have helped such as U-net architecture and Mask-RCNN has helped in our task.
How these architectures work and classify images is the motivation here.
5. 1.3. Objectives
3-01-2023 Image Segmentation Using Machine Learning Department of CSE, BMSCE
The objective of our project is simple. There are two of them firstly since we know that computer can only
understand the numbers so our first objective is to make computer understand the images. With the release
of the Pytorch and tensorflow it has helped us in achieving.
This is done by understanding what exactly the images are made up of and how computer perceive them. It
is one of the technologies that help digital world interact with the physical world. Second Objective is to
understand how these technologies work and various architecture used in these. Thus, we will demonstrate
the following architectures and show how they work.

Authors: NAHIAN SIDDIQUE, SIDIKE PAHEDING, COLIN P. ELKIN and VIJAY
DEVABHAKTUNI
In this paper, it was aimed to provide a starting point for researchers who wish to explore U- net, which is a
powerful deep learning model used extensively for medical image segmentation. To do so, firstly we started
with the definition of Unet and what it is and then we explored the many variants of Unet and its diverse
applications on a multitude of image modalities. We also examined the major deep learning methods and
their application areas for all of the papers in this survey. Indeed U-net based architecture is quite
groundbreaking and valuable in medical image analysis. We also saw that the growth of U-net papers since
2017 lends credence to its status as a premier deep learning technique in medical image diagnosis. Thus,
despite the many challenges and limitations remaining in deep learning- based image analysis, we expect U-
net to be one of the major paths forward.
8. U-Net: Convolutional Networks for Biomedical Image
Segmentation

Author: Olaf Ronneberger, Philipp Fischer, and Thomas Brox
This paper introduces the Unet architecture and talks about its architecture and design when it was designed
for first time. It also shows us the experimental details which show it has high accuracy than another model
despite using less dataset. It also shows how it is beneficiary for medical field. The u-net architecture
achieves very good performance on very different biomedical segmentation applications. Thanks to data
augmentation with elastic deformations, it only needs very few annotated images and has a very reasonable
training time of only 10 hours on a NVidia Titan GPU (6 GB). We are sure that the u-net architecture can be
applied easily to many more tasks.

This paper talks about Mask-RCNN and also about its application and working. It is faster RCNN and also
instance segmentation and talks about various of the Mask – RCNN applications and also talks about the
implementation details and also compare them to many other architectures like FCIS+++ and have shown to
outperform them. The experiment was done on the coco dataset 2015-2016 and also. But one thing is clear
from it is that it can used for many more things.
10. Classification of Image using CNN
3-01-2023 Image Segmentation Using Machine Learning Department of CSE, BMSCE
Authors: Md. Anwar Hossain and Md. Shahriar Alam Sajib
This paper focuses on Convolutional Neural Networks which currently is the state-of-art technique for image
classification. The authors have used the CIFAR-10 dataset which has around 60,000RGBimages. It has ten
classes, and they are an airplane, automobile, bird, cat, deer, dog, frog, horse, ship, truck. The images are of
size 32x32 pixels. The dataset consists of 50,000training and 10,000 testing examples. Optimization
algorithm used is the Stochastic Gradient Descent algorithm (SGD) which is a variation of Gradient Descent
algorithm (GD). Upon successful training of the images, among 10,118 test cases, the model misclassified a
total of661 images after three hundred epochs which corresponds to 93.47%recognitionrate. Authors also
found that higher the number of epochs the higher would be the accuracy.

3-01-2023 Image Segmentation Using Machine Learning Department of CSE, BMSCE
● Gradient Descent
● Stochastic Gradient Descent
● Backpropagation
The algorithm and the techniques go hand in hand for efficient and fast execution. Techniques help reduce the
complexity of data on which algorithms work on. The techniques make sure to get rid of some extreme edge
cases with which our program might crash or with which development time would increase. Thus techniques
are equally important to algorithms.
14. 4. Tools used
3-01-2023 Image Segmentation Using Machine Learning Department of CSE, BMSCE
Tools that were used to learn and implement CNN model were mainly frameworks and packages that were
open source and implemented in python. These packages helped us get a faster grasp of the field and eased the
task of understanding and solving the problem, also to solve some trivial problems. Yet one should not just use
the packages but must also understand the working of the packages. Under the hood mechanism must also be
learnt so that any future problems which require deeper understanding of the field could be solved.
Tools that were used were:
● TensorFlow
TensorFlow is an end-to-end open-source platform for machine learning. It has a comprehensive, flexible
ecosystem of tools, libraries and community resources that lets researchers push the state-of-the-art in ML
and developers easily build and deploy MLpowered applications.
15. 3-01-2023 Image Segmentation Using Machine Learning Department of CSE, BMSCE
● Matplotlib
Matplotlib is a comprehensive library for creating static, animated, and interactivevisualizations in
Python. Matplotlib makes easy things easy and hard things possible.
● NumPy
This is a package that is used for making efficient and multi-dimensional arrays that are efficient. This
package also includes many features like Random number generation, generation of values between a range
with equal difference between them and so on. Basically this package is used to play with numbers and arrays.
These were the tools that were selected for the implementation.
The modules were implemented on Kaggle.

MODULE 1: UNET – ARCHITECTURE
U-Net architecture is a deep learning image segmentation architecture introduced by Olaf Ronneberger,
Philipp Fischer and Thomas Brox in 2015. It’s an encoder-decoder architecture convolutional neural network
that was specifically designed tobe used in Biomedical Imaging.
The main goal for this architecture was to tackle two important issues in the field of medical imaging which
are:
1. Lack of large training datasets –
Traditional convolutional neural networks with fully connected layers, require large datasets because of the
large number of parameters needed to learn. Since medical imaging has small datasets, this architecture ensures
maximum learning from the information provided because a fully connected layer is replaced with series of up
convolutions on the decoder side.

2. Capturing context accurately at different resolutions and scales.
Its U shape design consists of two parts. The left side is known as the contracting path or encoder path,
where repeated typical convolutions are applied followed by ReLU and max pooling operations. The right side
is known as the expansive path which has transposed 2D convolutional layers where upsampling technique is
performed.

3-01-2023 Image Segmentation Using Machine Learning Department of CSE, BMSCE
Modern methods used to perform image segmentation use dilated convolutions at the core to extract high-
resolution features. This architecture is used for instance image segmentation which extends Faster R-CNN
(an architecture proposed by Shaoqing Renetal to eliminate selective search and allow the network to learn
region proposals) by adding an object mask predictor as a parallel branch to bounding box recognition.
