I have a binary image consisting of characters (alphanumeric), I can find the total number of characters in the Image but How do I find the nth charecter
I have also attatched the image, how do i find out the 5th character in the image?

filename = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/1152713/AlphanumericBinaryImage%20copy.png';
I = imread(filename);
t = ocr(I)
t =
ocrText with properties: Text: 'GJ03ER0563↵↵' CharacterBoundingBoxes: [12×4 double] CharacterConfidences: [12×1 single] Words: {'GJ03ER0563'} WordBoundingBoxes: [95 59 442 70] WordConfidences: 0.8790
n = 5
n = 5
t.Words{1}(n)
ans = 'E'
This would need a slight bit more work if there were multiple words and you wanted to know the n'th character wrapping through the words (for example, the 15th character from the beginning.) One of the questions would be whether the break between words should count as a letter for this purpose -- are you effectively transcribing the text (which would expect a space between words) ?

For this task each characters are separated by a space and the task is completed, I wonder how characters in a sentence where words are separated by spaces are detected?

The Words property would be a cell array of character vectors.
