3. INTRODUCTION
• Cancer is a condition in which cells in the body become uncontrolled.
• Lung Cancer starts in the lungs and spread to lymph nodes or the organs such as brain
inside the body.
• Cancer can potential spread to the lung from the other organs. Various CT Scan
image were obtained from various sources.
Lung Cancer may be divided into two sub categories :-
1.Non Cancerous Tumor 2.Cancerous Tumor

4. 1.2 DEEP LEARNING APPROACH
IT is a sub set of machine learning that uses neural network with at least 3 layers compare to a
network with just one layer can delivermore accurate result. BOTH RNN and CNN are used in
deep learning dependingon the application.
This project consists of four major stages, the first stage is Image acquisition, the second stage is Image
Processing Techniques, third stage is consists of Image Segmentation operations & the fourth or the last
stage is Feature Extraction of any image

7. PREPROCESSING :-
A preliminary processing of data in order to prepare it
for the primary processing or for further analysis.
Plot Histogram
Noise Detection
Salt & Pepper Noisy Image
Filter by Sobel Operator
Gray Scale Image
Pre-Processing Operations:
FIG4.Algorithm for Preprocessing ofCT Image
In pre-processing technique we
basically follow three step….
➢ Plot the histogram
➢ Detect the Noise
➢ Use a suitable filter to removenoise

8. NOISE PRESENT IN THIS DATA SET OF CT
IMAGES
After the pre-processing of the CT images we have
found a same type of noise present in our image and i.e IMPULSE VALUED
NOISE that is also known as SALT AND PEPPER NOISE.
SALT AND PEPPER NOISE :-
This type of noise is also called data drop noise because statistically its drop
the original data values.
In this type of noise some pixel value is replaced by the the 0 or 255
(minimum i.e dark or maximum i.e bright)pixel values.
This type of noise is clearly seen in the data transmission of image .In this the
pixel valuve of image is replaced by the corrupted value i.e either 0 or 255.

9. Image Enhancement:
Enhancement Techniques:
➢ Using Histogram Equalization
➢ CLAHE Techniques
Histogram Equalization
- Enhancement technique basically used to improve the
contrast in images by stretching out intensity range of image
pixel value.
It is a techniquewhich is used to improve the quality of the image & to get the betterimage than the
provided one
CLAHE Method
- : It is Contrast-limited adaptive histogram
equalization (CLAHE). It works on small areas of an image
calledtiles rather than the complete image.

Sobel filter
“THE SOBEL METHOD or SOBEL FILTER IS A GRADIENT BASED METHOD THAT LOOKS FOR STRONG CHANGES IN
THE FIRST DERIVATIVE OF AN IMAGE.”
The sobel filter edge detectoruses a pair of 3*3 convolutionmasks, one estimating the gradient in the
x - direction and the otherin theY – direction.

16. Performance Analysis of Parameters
1. PSNR: The PSNR computes the peak signal-to-noise ratio, in decibels, between two images.
2. SSIM: The Structural Similarity Index (SSIM) is a perceptual metric that quantifies image quality degradation caused
by processing such as data compression or by losses in data transmission.
3. MSE: The MSE represents the cumulative squared error between the compressed and
the original image, whereas PSNR represents a measure of the peak error.
4. Energy: The term energy describes the local change of a certain quality of the image. An example of quality
would be brightness or intensity. Energy is specifically important for applications such as image compression
5. Contrast: It is created by the difference in luminance reflected from two adjacent surfaces. In other words,
contrast is the difference in visual properties that makes an object distinguishable from other objects and the
background.
6. Entropy: The entropy or average information of an image is a measure of the degree of randomness in the
image.

18. SEGMENTATION :-
➢ Segmentation is basically defined as sub
division of image into its constituent regions
or object. The level of detail to which the
subdivision is carried depends on the
problem being solved.
➢ THRESHOLDING:it converts the RGB image into a
Binary image i.e. black and white image which has only
two shades which represent the level 0 and 1 only the
thresholdvalue for this will be lies between 0 and 1
because it has only two levels., after achieving the
thresholdvalue; image will be segmented based on it.

19. OBJECTIVE
This Project is mainly based on Image Processing using Deep Learning Techniques. In this work MATLAB have
been used through every proceduremade.
- To study the medical image processing underthe conceptsof MATLAB
- The Main Objective of this project is to find out the early stage of lung cancer and explorethe accuracy levels
of various deep learning algorithms.
- Removing noises from several CT Scan Image using several denoising filters
- Image Enhancement using Histogram Equalization/CLAHE Method
- Image segmentation using ThresholdingApproach.
- Extractingthe necessary information from the resultant output images.

20. RESULT & CONCLUSION
As we know Lung Cancer is one of the dangerous Diseases in the world. An image improvement technique in developing for
earlier disease detection and treatment stages. Correct Diagnosis and curly detection of lung cancer can increase the survival rate.

21. FUTURE WORK
We are aiming to get the more accurate results by using various enhancement and segmentation technique, different
segmentation strategies and calculations are the root idea of digital image. processing the more accurate rent will be more
helpful and good for the diagnosis solution and the penon can have more chances of survival from this dangerous disease and
we can do one more thing apart from using different strategies we can use a fusion method of all this techniques or the hybrid
methods to get the more accurate result. We can also develop the system as a real time system in future It means the system will
work at the time of diagnosis as well as with the time when we take the (CT) images, the advantage of the real time system
will be that it helps the person to cure the disease as soon as possible and provides a help for curly treatment so the survival
chance can be increase. In future by parameter and area calculation of the tumor at the time of detection we can also find that
tumor has been in which stage.
I will work to find several other parameters in detection of cancerous cell while extracting the features of the resultant images
of lung. Parameters are as follows:
