This paper proposes a rectangle expansion model, which is deduced from active contour model, especially for page layout analysis. The advantage of this model is the robust flexibility; there is no need to set so many thresholds as conventional method. Page layout analysis is an important part of an OCR system to implement printed documents digitization, so this approach can improve the performance of character recognition.
