Hi Mayank, To clarify, are you attempting to extract image metadata (e.g., timestamp, width, height) or convert a photo/graphic of text into a text string using optical character recognition (OCR).
If the former (metadata), Joe has you on the correct track for digging deeper. If OCR, has been done by others with NiFi using custom processors. Keyword search is "NiFi OCR". I would recommend giving Jeremy Dyer's Tesseract Processor [1] a look. Here is a guide Jeremy published [2].

Did you look at the flow file attributes after the extraction? Can you share a jpeg you're using that is not working as you'd expect?
