N2 - In this paper a multiple frame based technique to enhance text in digital video is presented. After extracting a reference text block, we use an image matching technique to find the corresponding text blocks in consecutive frames. We register these text blocks to subpixel levels by using image interpolation techniques to improve both correspondence and text resolution. The registered text blocks are averaged to obtain a new text block with a clean background and a higher resolution. Experiments conducted on several video sequences show that our enhancement scheme can improve the accuracy of commercial off-the-shelf OCR considerably.
