Hello, I want to obtain the space between the two words in the given image(i.e,the space between 'A' and 'MOVE','MOVE' and 'to' so on..)i want the space in terms of mm(millimeters). Please help me.Thank you

I suggest that you look at the documentation for the Mathworks ocr() routine. It mentions the name of the tool that they use. You can then search for information about that tool and find the paper that was written about it and the site with the long description of how it works. Included there is a description of the three or four different processing layers that they found that they needed to go through in order to determine the number of pixels between the end of one word and the beginning of the next. If I recall correctly, it is something that they found that they were not able to do until they had already tentatively recognized two adjacent words and checked the dictionary and the corpus statistics to determine the probability that the two adjacent words were really one word with a longer spacing between letters.

To phrase this a different way: you cannot just use spacing between letters to determine whether you have reached the end of a word when you are using handwritten letters. Because of that there is no easy way to determine the space between words—because without going through a lot of work you are not sure whether a gap is a gap between letters in the same word or a gap between adjacent words. Of you were hoping to be able to break up the text into words according to spacing and then apply recognition one word at a time, that is not going to work.

i used your code and modified that to detect space between pixels as shown in pic attached

%//////////// your code ////////////////////////////////////

clc;    
clear all
close all
format long g;
format compact;
fontSize = 20;
fullFileName = fullfile(pwd, 'capture.png');
grayImage = imread(fullFileName);
[rows, columns, numberOfColorBands] = size(grayImage);
if numberOfColorBands > 1
  grayImage = grayImage(:, :, 2); % Take green channel.
end
% Display the original gray scale image.
figure(1)
imshow(grayImage, []);
title('Original Grayscale Image', 'FontSize', fontSize, 'Interpreter', 'None');
binaryImage = grayImage > 128;
figure(2)
imshow(binaryImage);
title('Binary Image', 'FontSize', fontSize, 'Interpreter', 'None');
hold on
%////////////// include this //////////////////////////////////////////
[m,n]=size(binaryImage);
[lab,num]=bwlabel(~binaryImage);
for i=1:num-1
    img_1=lab==i;
    img_2=lab==i+1;
      [r,c]=find(lab==i);
      [r1,c1]=find(lab==i+1);
      if(min(c1)-max(c) > fontSize)
          line([min(c1) max(c)],[round(m/2) round(m/2)],'LineWidth',3);
          text((min(c1)+max(c))/2,10,num2str(min(c1)-max(c)));
      end
end
hold off

try use code in this way

clc;    
clear all
close all
format long g;
format compact;
fontSize = 20;
fullFileName = fullfile(pwd, 'segmented_line.png');
grayImage = imread(fullFileName);
[rows, columns, numberOfColorBands] = size(grayImage);
if numberOfColorBands > 1
  grayImage = grayImage(:, :, 2); % Take green channel.
end
% Display the original gray scale image.
figure(1)
imshow(grayImage, []);
title('Original Grayscale Image', 'FontSize', fontSize, 'Interpreter', 'None');
binaryImage = grayImage;             %> 128;
figure(2)
imshow(binaryImage);
title('Binary Image', 'FontSize', fontSize, 'Interpreter', 'None');
hold on
%////////////// include this //////////////////////////////////////////
[m,n]=size(binaryImage);
se=strel('disk',8);
binaryImage1=imdilate(~binaryImage,se);
binaryImage1=bwareaopen(binaryImage1,500);
[lab,num]=bwlabel(binaryImage1);
figure(3)
imshow(binaryImage)
hold on
for i=1:num-1
    img_1=lab==i;
    img_2=lab==i+1;
      [r,c]=find(lab==i);
      [r1,c1]=find(lab==i+1);
      if(min(c1)-max(c) > fontSize  && max(c1)-min(c1)>10)
          line([min(c1) max(c)],[round(m/2) round(m/2)],'LineWidth',3);
          text((min(c1)+max(c))/2,10,num2str(min(c1)-max(c)));
      end
end

dear meghashree try this code

clear all
close all
clc
image=imread('capture.png');
figure(1)
imshow(image)
drawnow
img_1=image(:,:,1)<150;
figure(2)
imshow(img_1)
drawnow
se=strel('disk',5);
img_2=imdilate(img_1,se);
figure(3)
imshow(img_2)
drawnow
[lab,num]=bwlabel(img_2);
for i=1:num
    [r,c]=find(lab==i);
    img_3=image(min(r):max(r),min(c):max(c),:);
      figure(4)
      subplot(3,3,i)
      imshow(img_3);
      drawnow
  end

could you please, help me how i can separate each words in text image , then separate letter as bounding box in each word , i tried this code but without feasibility.

 {
%%Image segmentation and extraction
%%Read Image
%%dis_letter =4;
%%dis_word =30;
close all;
clear all;
fontSize = 20;
imagen=imread('scan0001.jpg');
%%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,15);
pause(1)
%%Show image binary image
figure(2)
imshow(~imagen);
title('INPUT IMAGE WITHOUT NOISE')
[m,n]=size(imagen);
%%Label connected components
[lab num]=bwlabel(imagen);
%%figure(3),imshow(L);
%%imtool(L)
% calculate distance between each label

%% figure(3), imshow(img_1);

%%figure(4), imshow(img_2);

%% Measure properties of image regions propied=regionprops(lab,'BoundingBox'); hold on %% Plot Bounding Box for n=1:size(propied,1) rectangle('Position',propied(n).BoundingBox,'EdgeColor','g','LineWidth',2) end hold off pause (1)

figure for i=1:num-1 img_1=lab==i;

img_2=lab==i+1;

 [r,c]=find(lab==i);
   [r1,c1]=find(lab==i+1);
 if(min(c1)-max(c) > fontSize  && max(c1)-min(c1)>10)
line([min(c1) max(c)],[round(m/2) round(m/2)],'LineWidth',3);
 text((min(c1)+max(c))/2,10,num2str(min(c1)-max(c)));
 figure(5), imshow(img_1);
 figure(6), imshow(img_2);
end
end

%% Objects extraction

%for n=1:Ne % [r,c] = find(L==n); % n1=imagen(min(r):max(r),min(c):max(c)); % imshow(~n1); % pause(0.5) %end }

I have a doubt in arrangement of code sections, help me please.

How do I use the values in the figure? for eg : if I want to take average of all the values?

sparsh garg 2021-8-28

Hey harjeet thanks for the code,in this we are able to figure out the spacing between two words.However for examples like this,I am also interested in looking at the spacing between the characters in a word.If anyone can give me pointers on how to go about this,it would be really useful.
