I need to extract the characters in the image.But,I get error.I have attached my code below.I need to extract all the characters in my image.Can anyone please help me in rectifying my error.

My error is:

Index exceeds array bounds.

Error in te (line 6)

word = results.Words{2};

% Load an image

Please check the variable:

results.Words

It is empty in your case.....ocr didnot capture any words.......As the variable is empty..you are getting an error.

It works fine.But,I don't get any output (i.e),I don't get any characters as output.What shouls I do?

Can you tell me what does

results.words

outputs? It is an empty cell. ocr doesnt throw any error it doesn't mean, it could capture the characters.

So how should I capture the characters.I have segmented all the characters from my image.Now,how should I capture the characters from it?My character segmentation code is attached below.Now how should I identify the segmented characters.I have attached my input image also.

clear all;
close all;
I = imread('test3.png');
BW = im2bw(I, 0.9);
BW = ~BW;
stats = regionprops(BW);
for index=1:length(stats)
if stats(index).Area > 200 && stats(index).BoundingBox(3)*stats(index).BoundingBox(4) < 30000
      x = ceil(stats(index).BoundingBox(1))
      y= ceil(stats(index).BoundingBox(2))
      widthX = floor(stats(index).BoundingBox(3)-1)
      widthY = floor(stats(index).BoundingBox(4)-1)
      subimage(index) = {BW(y:y+widthY,x:x+widthX,:)}; 
      figure, imshow(subimage{index})
      end
  end
