This paper proposes a new approach to adaptively detect and to code the region of interest of scanned document
which makes use of the result of a fast segmentation algorithm based on the bi-level reduced image in order to satisfy the needs of application of the digital library. The paper Frstly describes in detail a block technique to reduce the original image
a modified smearing method to simplify computation and a fast segmentation algorithm. Based on the result of document segmentation
the paper then introduces a generating algorithm of ROI mark image and the max-shift method of document compression. Finally the paper shows an example of compressing scanned document
