Read the output line by line

How to read the text line by line? i dont know where to put it. Now, it show rubbish output. this is the code.

[file,path]=uigetfile({'*.jpg;*.bmp;*.png;*.tif'},'Choose an image');
s=[path,file];
picture=imread(s);
[~,cc]=size(picture);
picture=imresize(picture,[300 500]);

if size(picture,3)==3
  picture=rgb2gray(picture);
  figure
  imshow(picture)
  title ('GRAY')
end
% se=strel('rectangle',[5,5]);
% a=imerode(picture,se);
% figure,imshow(a);
% b=imdilate(a,se);
threshold = graythresh(picture);
picture =~im2bw(picture,threshold);
picture = bwareaopen(picture,30);
imshow(picture)
title ('first')

if cc>2000
    picture1=bwareaopen(picture,3500);
else
picture1=bwareaopen(picture,3000);
end
figure,imshow(picture1), title ('show')
picture2=picture-picture1;
figure,imshow(picture2), title ('thresh 1')
picture2=bwareaopen(picture2,200);
figure,imshow(picture2), title ('BoundingBOx')

[L,Ne]=bwlabel(picture2);
propied=regionprops(L,'BoundingBox');
hold on
pause(1)
for n=1:size(propied,1)
  rectangle('Position',propied(n).BoundingBox,'EdgeColor','g','LineWidth',2)
end
hold off


figure
final_output=[];
t=[];
for n=1:Ne
  [r,c] = find(L==n);
  n1=picture(min(r):max(r),min(c):max(c));
  n1=imresize(n1,[42,24]);
  imshow(n1)
  title ('alphabet found')
  pause(0.2)
  x=[ ];

totalLetters=size(imgfile,2);

 for k=1:totalLetters
    
    y=corr2(imgfile{1,k},n1);
    x=[x y];
    
 end
 
 t=[t max(x)];
 if max(x)>.45
 z=find(x==max(x));
 out=cell2mat(imgfile(2,z));

final_output=[final_output out];
end
end

file = fopen('TextDetect.txt', 'wt');
    fprintf(file,'%s\n',final_output);
    fclose(file);                     
    winopen('TextDetect.txt')

my output are like this : and the 'DO' part cant be read.

Hi,

Not sure if I understand the problem correctly... are you trying to given an image with text get the text into MATLAB?

If yes, there is a simple way: OCR is in the Computer Vision System Toolbox. The example is really useful.

If no, can you further explain what you are looking for:) It also is often useful to share a "dummy" image with the community, so we can use it for helping you.

hi!, thanks for the respond. Actually i want to insert a code that read the output line by line because u can see from the ouput that i get, the word is scramble. I think it read the word (from the image) vertically. And about the OCR, i already use that code but it gives a wrong output, it can only gives the exact output if the image is really clear and no shadow like my picture. This code is best when the image only have one line or two line.
