# PHD THESIS MATLAB CODE

Matlab play an important role for research scholars to effectively done their PHD thesis work. We Provide Phd Thesis Matlab Code for academic students. Image processing concepts are selected to done PHD thesis and it should be implemented using matlab simulation.

Matlab Processes:

• Matlab has several vectorized operations.
• Matlab graphical output is optimized for interaction.
• Matlab allows to perform numerical calculations and visualize results.
• No need for complicated and time consuming programming.
• Matlab allows users to accurately solve problems, produce graphics easily and produce code efficiently.

PhD Thesis Matlab Code for Signal generation and visualization:

set(gcf,’NumberTitle’,’off’);
set(gcf, ‘Name’,’Signal Generation using Signal Processing Toolbox’);

Fs = 2000; % Sampling Frequency: 2000 Hz
t = 0:1/Fs:1; % Time 1-sec duration
f = 50; % 50 Hz signal

% Generate Known Signals

% Square Wave
sqWave = square(2*pi*f*t);
plotSig(1,sqWave,’50 Hz Square Wave’);

% Sawtooth wave
sawtoothWave = sawtooth(2*pi*f*t);
plotSig(2,sawtoothWave,’50 Hz Sawtooth Wave’);

% Sine waveform
sineWave = sin(2*pi*f*t);
plotSig(3,sineWave,’50 Hz Sine Wave’);

%Chirp Signal
chirpSig = chirp(t, 0,0.5,150);
plotSig(4,chirpSig,’Linear Chirp Signal’);

input_image_path = ‘image1.jpg’;

PhD Thesis Matlab Code for skin color detection:

I=double(I);[hue,s,v]=rgb2hsv(I);
cb = 0.148* I(:,:,1) – 0.291* I(:,:,2) + 0.439 * I(:,:,3) + 128;
cr = 0.439 * I(:,:,1) – 0.368 * I(:,:,2) -0.071 * I(:,:,3) + 128;[w h]=size(I(:,:,1));
for i=1:w
for j=1:h
if 140<=cr(i,j) && cr(i,j)<=165 && 140<=cb(i,j) && cb(i,j)<=195 && 0.01<=hue(i,j) && hue(i,j)<=0.1
segment(i,j)=1;
else
segment(i,j)=0;
