How can I read text from pdf in Matlab? I tried this code
a=OCR(unit8(test.pdf);
After the execution of the above code value of a is empty.
There is any other option which one I can use.

the image file itself is gone, converted to pixel representation.

It is probably easier to invoke external software to extract the images. Once you have the images you can ocr them. http://www.peteryu.ca/tutorials/publishing/pdf_manipulation_tips2

I tried this but not able to find the exact solution. I also tried OCR but it works for a small image.
Thanks
