Abstract :
The vast majority of copied documents generally consist of text, and the copy quality mostly depends on the text´s reproduction quality. A new technique to enhance dark text on light background of scanned mixed mode documents (containing text, graphics and photo) is presented to improve copy quality. This technique incorporates various image processing filters that enhance dark text without disturbing image and graphics content of scanned documents. Copy samples are provided to show improved text and overall copy quality
