I have a very low resolution, almost pixelated images for processing. The characters can be recognized if zoomed in and a quick eye scan is performed with the aid of basic English grammar and vocabulary set. I have a tried many ICRs and OCRs, but none proved to be useful. Is/Are there any OCR/s that I might have possibly missed on? P.S.The cursive font seems to be the problem.
Tesseract 4.0 is probably your best bet for getting accurate results from images like that.
It's open source and is available for Linux (As well as binaries for Windows).
I suggest giving it a shot with the image resized to about 300DPI and in black and white, as per Izzy's Comment.
If the results aren't as accurate as you would like, you could always Train the Neural Network for that image so you can get a more accurate OCR for future images of that relative type.
