Abstract
A text-recognition system and method include a trained classifier configured to identify a font of a frame of text line image. The system also includes an adaptive sliding window configured to divide the frame into a plurality of cells. A first cell is located around a prominent writing line of the text line image. Additional cells are located above the prominent writing line and below the prominent writing line, such that each of the additional cells above the prominent writing line has a same percentage of ink-pixels and each of the additional cells below the prominent writing line has a same percentage of ink-pixels. The system also includes a font-specific feature parameters database configured for extraction of text features from each of the cells. The system also includes one or more trained font-specific recognizers configured to recognize the extracted text features using an associated font-specific recognizer for the identified font.
