Perhaps the template you're using isn't made for your work... Try modifying it or creating your own template. Here are a few suggestions; use an "image segmentation and extraction" code to crop the letters or characters and store them in a location. Use the appropriate template creation m-file to create the template. You can find these codes at the matlab "File Exchange".

ya.. i have seen d code posted dere and m using dat code. but tell me how to differentiate between 'C' and 'c' in template matching.. similarly in 'S', 's'. 'V' and 'v' like that..

Means when i am going to match the letter with the template then it is not differentiating between uppercase and lowercase as above stated.

Please guide..

Thanks

I don't know which of the OCR versions you are using. If you're using the one with both upper & lower case letters then consider replace the small character images in the folder "letters_numbers" with your own, cropped from the same image you're working on. Then run the "create_template" m-file to create your own template.

use

regexp(yourstring,'\w*')
regexp(yourstring,'[a-z]')

I am not going to match a regular expression..

I have to match the letters with its corresponding templates..

SO wat is this for?

Shavi, you did not specify that you were using OCR, and you did not specify that you were using an OCR routine that is not provided by Mathworks. http://www.mathworks.com/matlabcentral/answers/36057-how-to-read-special-characters-using-matlab-in-ocr
