We are highly indebted to Babaria Institute of Technology for their guidance and constant supervision as well as for providing necessary information regarding the project & also for their support in completing the project, our project’s internal guide helped us a lot in this project and they are always there for our solution.
We would like to express our gratitude towards our parents ;members of Babaria Institute of Technology for their kind co-operation and encouragement which helped us in completion of this project. We would like to express our special gratitude and thanks to industry persons for giving us such attention and time.
Our thanks and appreciations also go to our colleague in developing the project and people who have willingly helped us out with their abilities.
The purpose of our project “Tumor Detection from Brain MRI Image” is to make people aware about the new technology and hence provide a technological buffer that helps people understand and process the current technology to benefit them in their day to day life.
This approach is made to make some improvements in addition with being updated to the new technology related to gesture controlling via mathematical algorithm. Here medical diagnosis through machine learning is considered to be important issues of artificial intelligence. Here in this project we present a machine learning approach to detect whether the MRI image of brain contains tumor or not. We are trying to make the design user friendly so that there will not be any problems while using. We hope that we would be successful in completing the project in a proper way.

Under the guidance of professor Ashish Prajapati, we the students of the Babaria Institute of Technology pursuing Computer Engineering are presenting our project “Tumor Detection From Brain MRI Image” which can be used as standard analytical tool for Brain Tumor Specialists around the world.
1.1 Problem Summary
If we talk about the number deaths that occur because of malignant brain tumor and other tumor then it will be in millions, here because of late diagnosis and false diagnosis the survival rate decreases, thus making it difficult to survive from these brain tumor diseases. The average survival rate for malignant brain is also low that is between 30-40%.
In this project we classified whether tumor is malignant or benign, size of tumor, category of tumor etc, which will help the specialists to take more informed decisions.
1.2 Aim and Objective of the project
Our Aim is to create an application which will take MRI images as input, segment the tumor in the image and transfer the segmented images to specialist’s id, these are analyzed by the specialists having all the case details via Web and Mobile application, this creates a directory of patients for the specialists, so that they can check it at any time via cloud.
Current manual tumor segmentation takes lot of time to segment out tumors in each individual slice in 3D image as a result of it effort increases.
Here the classification of tumor will be accurate if tumor segmentation is automated using deep learning techniques it will increase the efficiency and accuracy significantly, it will also reduces time and effort.
The statistical analysis of MRI images will also help the specialists to find details like tumor size etc, it will result into the accurate and precise treatment plans for patients.
1.3 Problem Specification
The objective of our current project is to remove/reduce the problems of the currently used method of segmentation i.e. manual segmentation performed by specialists.
The main problems of the current method are:
Prone to Errors
Not Very Accurate
Depends on Experience of the Specialist
Thus, to resolve the above mentioned problems we plan to propose a method for automatic segmentation of tumor from brain MRI using deep learning.
1.4 Literature Review
Review paper we referred to indicates four phases for effective detection of brain tumor from MRI images, it consists of four phases:
In these phase MRI input image is processed in such a way that it becomes suitable for the further processing.
In these phase image which contains unwanted noise is removed which gets added due to MRI scan.
These phase include to improve the appearance i.e. contrast and visibility.
In image enhancement Gaussian filter is applied to improve quality of image and removal of noise.
Segmentation In Segmentation EDPSO method is used for detection and segmentation of tumor from MRI images.
Neuro-fuzzy is sophisticated framework for multi-object classification. Fizzy rules are selected to classify an abnormal image to corresponding tumor type.
This technique is fast in execution, efficient in classification and easy in implementation.
1.5 Plan of work
To make the development process of our project fast, efficient and smooth, we have decided to divide the project in to a set of task which are as follow:
Surveying the cancer specialist hospitals to know in detail about the current problems in the manual method of segmentation.
Gathering the required training data-set for training our model from various hospitals and online open sources.
Finding a method to convert the 3D MRI images into 2D image slices and a way to represent them so that the specialists can view each image slice by slice.
Searching and testing suitable automated deep learning models such as BiSeNet, U-Net, SegNet, etc. to find a model which suits our requirements and gives best result with our current training data-set.
After finding the suitable model, we will develop the model and keep the model for training using the training data-set acquired from various sources.
After the training is over, we test the model using test data-set to check whether the model works as intended and give high accuracy.
Finally, we will consult various specialists regarding our project and take their suggestion to further improve the project and make it better for them.

1. Kailash was a farmer, he was diagnosed with brain tumor but due to scarcity of brain tumor detection tools and specialists in the village hospital, he was unaware of the disease and later when he went to city hospital for diagnosis it was already too late to cure the tumor and he ultimately died.
2. In one hospital, because of large number of MRI images to be segmented, quick segmentation with high accuracy became difficult for the radiologists, as a result the life expectancy decreased because of the delay in treatment.

4.1Advantages of the System
As we know by now that manual segmentation of an MRI image is a tedious task and takes a lot of time thus making the method inefficient, and along with the segmented parts of the MRI, doctors can plan out efficient recovery paths by considering relevant analytical data but manual segmentation does not provide any relevant analytical data for the doctors to consider. When taking real life situations into account a single radiologist might take multiple MRI scans throughout a single day, thus this additional time required for manual segmentation adds up. This additional time can instead be used to take even more MRI scans.
One of the underrated advantages of the system is that it transfers all this medical data to the cloud with state of the art security, thus making the system secure and more accessible when compared to physical repositories of data.
Thus the automated segmentation method using deep learning is not just efficient but also offers analytics that can possibly change the space of brain tumor research for the upcoming future.
4.2 Unique Features
Our product provides analytical data like Volume of varieties of tumors
Rate of growth with multiple MRIs of the same patient
Faster and more efficient than manual segmentation
Combines medical expertise with the advantages of data analytics
Minimizes manual labor and large repositories by saving all the data in the cloud
Easily accessible on demand
4.3 Scope of further work
The methodology used for this project can further be improved and can be applied in a variety of fields in medical science like surgery and bone damage repair and in the future with a large enough dataset, this model might even cluster multiple cases and suggest possible treatments that have worked in the past for various other cases.
