Abstract

In accord with embodiments consistent with the present invention, a first action in recognizing text from image and video is to locate accurately the position of the text in image and video. After that, the located and possibly low resolution text can be extracted, enhanced and binarized. Finally existing OCR technology can be applied to the binarized text for recognition. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
