Hello guys, I’m trying to use Tesseract on images taken with a hand held cellular camera. When the picture is taken with a less than perfect ligthing, the images are often blured (I assume this is caused by longer exposure time and shaky hands) and recognition accuracy drops very badly.
Is there any pre-proccessing I could do on the image before passing it to Tesseract? Sharpening filter? I need something light that would could be run easely on smart phone. The images are usually snapshots from magazines text columns and then cropped to include only the text. Also, images are RGB and passed directly to TessBaseAPI::TesseractRect() Thanks!
