A workaround is to install tesseract on your PC.

The workflow in Matlab is to print the image you want to run OCR to a .tif (.jpg works too), do a system call to tesseract, then read its output into matlab.

For example:

imwrite(im,'image.tif'); 
system('tesseract image.tif res'); 
a = importdata('res.txt');

you may want to use textscan instead of importdata....

That article still requires using the OCR function, and therefore computer vision toolbox.

The topic of recognizing text is known as Optical Character Recognition, often abbreviated to OCR. Any technique that can recognize text in images is an ocr technique. It is not possible to recognize text without using ocr, because anything recognizes text is defined to be ocr.
