i want to be extract text from image, i try to below code but i did not get correct output ,please help me to solve my problem.........

%%Image segmentation and extraction
%%Read Image
imagen=imread('C:\Users\shankar\Documents\MATLAB\filtering\text.jpg'); %%imagen   365x550   200750  logical   
%%Show image
figure(1)
imshow(imagen);
title('INPUT IMAGE WITH NOISE')
%%Convert to gray scale
if size(imagen,3)==3 % RGB image
  imagen=rgb2gray(imagen);
end
%%Convert to binary image
threshold = graythresh(imagen);
imagen =~im2bw(imagen,threshold);
%%Remove all object containing fewer than 30 pixels
imagen = bwareaopen(imagen,30);
pause(1)
%%Show image binary image
figure(2)
imshow(~imagen);
title('INPUT IMAGE WITHOUT NOISE')
%%Label connected components
[L Ne]=bwlabel(imagen);   %%Ne   1x1     8  double
%%Measure properties of image regions
propied=regionprops(L,'BoundingBox');  %%%%Measure properties of image regions
hold on
%%Plot Bounding Box
for n=1:size(propied,1)  %%n is single matrix 1X1
  rectangle('Position',propied(n).BoundingBox,'EdgeColor','g','LineWidth',2) %%g =green color
end
hold off
pause (1)
%%Objects extraction
figure
for n=1:Ne
  [r,c] = find(L==n);  %%n is single matrix 1X1 , L = 365x550 , r= 31X1 matrix
  n1=imagen(min(r):max(r),min(c):max(c));
  imshow(~n1); %% n1    12x7        84  logical 
  pause(0.5)
  imsave();
end
%%CROP
 %[area, bbox] = step(hblob, imagen);
