android OCR?

i'm currently doing a project on text recognition based on a image capture in android phone. I want to ask how the text can be extracted from image?

Does have any openCV or OCR tesseract tutorial for extracting ?

Solution

The fastest way (maybe not the ideal) is to implement the following steps:

• Use OpenCV to detect the paper sheet or the text area;
• Perform any processing necessary to deskew the image (if necessary);
• Save the image to disk as TIFF;
• and finally, call Tesseract cmd-line application passing the TIFF image as parameter to start the text recognition process.
