This paper dealts with a method for using Hausdorff distance to analyse the page layout based on bottom-up approach through Qo relation. Firstly, objects were isolated by out-contours. Then, the objects have the size smaller than a given tolerance would grouped by nearest Hausdorff distance to create a region. The other, which has smaller size, would be analysed as a document image. T6m t~t. Bid bao nay de c~p dgn ph an tich trang van bdn h5n hop thanh cac than h phan theo tigp c~n dU'lyilen
