Project Methodology: Color Image Converted in to Gray scale Then by using “Sobel filter” detected the required

Text Subtract the selected required Text from the Gray

scale starting image Adjust gray color at extracting place with

neighbors color Convert the image again back from gray to RGB scale

by comparing colors of the Starting image Add text “buhahaha ” below the good night location

text Add the smiley to the image

1)Directly ADD the Image of Smiley (or)2)Made simple Smiley by Polygon

Save the final image

MATLAB CODE:clc;clear all;%k=input('Enter the file name','s'); % input image; color image

Functions Used in MATLAB:

1. For GRAY to RGB conversion function R=gray2rgb(img1,img2)ticclc;warning off;imt=img1;ims=img2;[sx sy sz]=size(imt);[tx ty tz]=size(ims);if sz~=1 imt=rgb2gray(imt);endif tz~=3 disp ('img2 must be a color image (not indexed)');else imt(:,:,2)=imt(:,:,1); imt(:,:,3)=imt(:,:,1); % Converting to ycbcr color space nspace1=rgb2ycbcr(ims); nspace2= rgb2ycbcr(imt); ms=double(nspace1(:,:,1)); mt=double(nspace2(:,:,1)); m1=max(max(ms)); m2=min(min(ms)); m3=max(max(mt)); m4=min(min(mt)); d1=m1-m2; d2=m3-m4;% Normalization dx1=ms; dx2=mt; dx1=(dx1*255)/(255-d1); dx2=(dx2*255)/(255-d2);



[mx,my,mz]=size(dx2);%Luminance Comparison disp('Please wait..................'); for i=1:mx for j=1:my iy=dx2(i,j); tmp=abs(dx1-iy); ck=min(min(tmp)); [r,c] = find(tmp==ck); ck=isempty(r); if (ck~=1) nimage(i,j,2)=nspace1(r(1),c(1),2); nimage(i,j,3)=nspace1(r(1),c(1),3); nimage(i,j,1)=nspace2(i,j,1); end end end rslt=ycbcr2rgb(nimage) R=uint8(rslt); tocend

2. For Circle made function [X Y] = circle(center,radius,n) THETA = linspace(0, 2 * pi, n);RHO = ones(1, n) * radius;[X Y] = pol2cart(THETA, RHO);X = X + center(1);Y = Y + center(2);end
