Introduction
The term MATLAB refers to the multi paradigm numerical computing process which is
produced by the Mathworks. It is one of the advanced computer software which is used
in the field of information technology. Image processing is one of the best applications
of MATLAB software where it detects and process image through numerical codes.
Aim and objectives
 To analyse the concept of image processing through MATLAB software
 To recognize the number plate of the vehicle
 To highlight and evaluate the method of image processing with the help of
MATLAB
 Review of papers
RECOGNITION OF VEHICLE NUMBER PLATE USING MATLAB
This journal paper was written by the Ragini Bhat and Bijender Mehandia in the year
2014. The objective of this investigation is to analyse the concept of MATLAB and
recognize the number plate of vehicles. According to the researcher the vehicle number
plate detection using MATLAB is one of the common topics for the investigation [1].
These papers reduce the research gaps occurred in the previous investigation and
provided in-depth analysis about number plate detection. The author also performed
this project on MATLAB software and compared results with the previous study. It is
analysed that the number plates of the vehicles are in different size and shape which
can be managed with the help of MATLAB software. The author used the morphological
and sobel edge detection methods in the MATLAB software because both are very
simple for the detection of number plates. In which researcher involved various key
aspects regarding the image processing such as vehicle image captured by the camera,
extraction of the number plate, segmentation and recognition process and display
vehicle number. From this study, it has been identified that the MATLAB is one of the
best platforms for designing and implementing the image processing project where it
uses the segmentation and recognition process to detect a number plate of the vehicle.

This journal study was written by the two authors such as Bassel shanwar and nizar
zarka in the year 2016. This paper is completely based on vehicle number plate
detection using MATLAB software. The aim of this investigation is to highlight the
importance of MATLAB software in the detection of the number plate. According to the
researcher, number plate recognition is one of the simplest projects which can be done
with the help of some codes and it can be performed in the MATLAB software [8]. The
main problem faced by the researcher is the detection of boundaries of the number
plates. Moreover, the investigator involves major two kinds of approaches such as
morphological operation and sobel edge recognition. It is observed that first, an image
of number plate captured through camera after that extraction process is used in order
to extract the number plate location. The author used the segmentation and recognition
processes for detecting the number plate of the vehicle. From this paper, it has been
observed that the morphological process is the very best technique to extract the
number plate location and the researcher used the neural network in order to detect the
characters of number plates.
TRACKING NUMBER PLATE FROM VEHICLE USING MATLAB
This paper was provided by the Manisha Rathore and Saroj kumara in the year 2014
and the aim of this study is to track the number plate of a vehicle with the help of
MATLAB technique. The researcher identified that in the field of traffic surveillance the
detection of the number plate is a very important task that can be done by using
MATLAB software [7]. It is analysed that the MATLAB has the potential to produce the
under defined function and provide a way to complete the image processing task by
using numerical computation. There are few steps used by the researcher for detecting
the number plate such as image acquisition, dilation of a picture, horizontal and vertical
edge processing, and segmentation and recognition process. It has been concluded that
the detection of number plate through MATLAB is 90% accurate and effective which can
easily recognize the character of the number plate.

recognition of number plate can be achieved by using MATLAB algorithm [3]. In which
the investigator used the surveillance system which involves acquisition, detection,
extraction and recognition process. From this paper, it has been analysed that traffic
surveillance is the best approach that can be used in the number plate detection project.
The researcher observed that there are few key factors which increase problems in the
detection of number plates such as weather situation, vehicle movement, and lighting,
license plate placement in the image and damage in the plate [2]. This paper provided
an in-depth analysis of the number plate detection and conducted numbers of projects
for recognizing the number plate. From this study, it has been concluded that the
detection of number plate using MATLAB is a more effective process which also provide
90% accuracy to find characters of number plates.

detection using MATLAB software. There are several journal papers involved in the
research for analysing the viewpoints of other authors. Moreover, the best research
methodology also increases the quality of the study and it also helps the researcher to
reduce the research gaps and issues occur during the investigation.
Research approach
It is one of the important parts of the research method that evaluate the cause of
choosing the specific process of research. Mainly, the research approach is divided into
various sections, for example, the deductive process and in-deductive approach [9]. The
in-deductive process is used to access the depth analysis of facts and data and deductive
approach is used for accessing the theoretical information about the research topic.
With the help of the formulation of a hypothesis, the investigator can accept and reject
the research process which is linked with the issues and challenges.

Research design
It is observed that the research design is an effective method for conducting research
about number plate detection using MATLAB. With the help of this process, the
researcher can receive the right direction in order to comprehend the study issue and
improve the overall effectiveness of the investigation. Such kind of research method
also helps the researcher for achieving the objectives of the study [10]. Furthermore,
the research design also involves the plan of investigation and helps them to make
answer the few questions about research work. In this study, the investigator will
involve two kinds of research designs such as qualitative and quantitative process. The
qualitative research focuses on the theoretical information about the research topic and
the quantitative research process focuses on numerical data and facts. Both research
designs will help researcher for understanding the concept of number plate detection
and reducing the issues developed during the investigation. By using, such kind of
research design the author can achieve the aims and objectives of this investigation in
specified time duration.
Research strategy
Such kind of method is beneficial for the investigation in order to assess the data
collecting methods by which research will improve the effectiveness of the paper. In
which, the researcher will use the literature review, journal papers, and online
resources for understanding the concept of number plate detection using MATLAB [4]..
During this investigation, the researcher will use the survey with only theoretical facts
and data about the MATLAB software and results will be compared with the theoretical
facts. Moreover, this type of research strategy will be involved for assessing the specific
investigation matter within the limitation of the MATLAB. The literature review will
collect the viewpoints of other researchers about number plate detection and analyse
the findings and results obtained by the previous studies. However, using an
appropriate research strategy will help the investigator to gain a better conclusion and
achieve better results.
Data collection method
The data collection technique is a more important step for research which will help the
researcher to analyse the theoretical and numerical data. In this study, the researcher
will use a secondary type method for collecting the facts and information about the
