Problems generating final image

I have a code that returns a single RGB value for every pixel. I run it over a loop through all pixels and I keep storing them in a matrix after every loop. In the end i have a matrix lets say out(412324,3) as the dimensions of the matrix. After reshape() and converting it to RGB matrix I try to get the final picture out of it.
My problems:- 1. The final picture is very different than expected. It is not a clear picture at all. 2. It is skewed. I have uploaded 2 pictures. One is expected and the other is obtained
Here is my code: numberOfImages=3; pic=imread('1.tif'); sizeOfY=size(pic,1); sizeofX=size(pic,2); totalSizeOfImage=sizeofX*299;
k=0; out= zeros(totalSizeOfImage,3);
for y=370:sizeOfY for x=1:sizeofX
for i=1:numberOfImages
filename=[num2str(i), '.tif'];
rgbImage=imread(filename, 'tif');
R = rgbImage(y, x, 1);
G = rgbImage(y, x, 2);
B = rgbImage(y, x, 3);
RGBMatrix(i,:) =[R,G,B];
end
for imageNumber=1:numberOfImages
match=0;
jitter=0;
for j=numberOfImages:-1:1
RedChannelDifference=abs(double(RGBMatrix(j,1))-double(RGBMatrix(imageNumber,1)));
GreenChannelDifference=abs(double(RGBMatrix(j,2))-double(RGBMatrix(imageNumber,2)));
BlueChannelDifference=abs(double(RGBMatrix(j,3))-double(RGBMatrix(imageNumber,3)));
if (RedChannelDifference+GreenChannelDifference+BlueChannelDifference)<=10
jitter=jitter+RedChannelDifference+GreenChannelDifference+BlueChannelDifference;
match=match+1;
end
end
match=match-1;
matchMatrixOfAllImages(imageNumber,:)=[match];
end
%fprintf('The maximum value of matches is : %d \n', max(matchMatrixOfAllImages(:)));
index=find(matchMatrixOfAllImages == max(matchMatrixOfAllImages(:)));
if size(index,1)>1
jitterMatrixOfAllImages(imageNumber,:)=[jitter];
% fprintf('Jitter values of ONLY MATCHES');
jitterMatrixOfMatchedImages=jitterMatrixOfAllImages(index,:);
indexForJitter=find(jitterMatrixOfMatchedImages == min(jitterMatrixOfMatchedImages(:)));
if size(indexForJitter,1)>1
indexOfPictureNeeded=indexForJitter(1,:);
filenameOfImage1=[num2str(indexOfPictureNeeded), '.tif'];
rgbImage1=imread(filename, 'tif');
R1 = rgbImage1(y, x, 1);
G1 = rgbImage1(y, x, 2);
B1 = rgbImage1(y, x, 3);
RGBMatrix1(indexOfPictureNeeded,:) =[R1,G1,B1];
k=k+1;
out(k,:) =RGBMatrix1 ;
else
indexOfPictureNeeded=indexForJitter(1,:);
filenameOfImage1=[num2str(indexOfPictureNeeded), '.tif'];
rgbImage1=imread(filename, 'tif');
R1 = rgbImage1(y, x, 1);
G1 = rgbImage1(y, x, 2);
B1 = rgbImage1(y, x, 3);
RGBMatrix1(indexOfPictureNeeded,:) =[R1,G1,B1];
k=k+1;
out(k,:) =RGBMatrix1 ;
end
else
jitterMatrixOfAllImages(imageNumber,:)=[jitter];
jitterMatrixOfMatchedImages=jitterMatrixOfAllImages(index,:);
indexForJitter=find(jitterMatrixOfMatchedImages == min(jitterMatrixOfMatchedImages(:)));
indexOfPictureNeeded1=indexForJitter(1,:);
filename1=[num2str(indexOfPictureNeeded1), '.tif'];
rgbImage2=imread(filename, 'tif');
R1 = rgbImage2(y, x, 1);
G1 = rgbImage2(y, x, 2);
B1 = rgbImage2(y, x, 3);
RGBMatrix2(indexOfPictureNeeded1,:) =[R1,G1,B1];
k=k+1;
out(k,:) =RGBMatrix2 ;
end
end
end
for i=1:totalSizeOfImage R(i,1) = out (i,1); G(i,1) = out (i,2); B(i,1) = out (i,3); end
R = reshape(R, 299, sizeofX); G = reshape(G, 299, sizeofX); B = reshape(B, 299, sizeofX);
RGB(:,:,1)=R; RGB(:,:,2)=G; RGB(:,:,3)=B;
