How to use OpenCV / Tesseract to recognise Text on a poster images

Dear All,

I am new to OpenCV and Tesseract. Currently, I am working on a project which needs to recognise text on some poster images. I tried Tesseract but the result is not very good. I am thinking of should I use OpenCV to pre-process the image before using Tesseract to recognise the text. Can anyone kindly give me some high-level directions on what kind of OpenCV technologies I should applyC:\fakepath\vip2_trim_80.jpg. I attached a sample image that I want to extract text from the image.

Thank you very much for your help.
