Heuristic adaptation method for heterogeneous document

摘要: The invention discloses a heuristic adaptation method for heterogeneous document. is used performing binary processing on the According to method, local layout analysis performed to-be-read region based judgment of types connected components with being basic objects from user click position which serves as seed point. During homogeneous expansion, an initial component, transverse initialization expansion measured according homogeneity, longitudinal new line searched for, whether previous needs continue judged line, continued till left/right and up/down lines all reach boundary, preliminary obtained. optimization, segmentation or combination conditions, so that aspect ratio optimized adaptive screen ratio. An original image corresponding final be adapted reading, can read previous/later exit reading state reselect region.
