Since the late 1990s the information extraction on web tables was probed into study, and at present, all the research on it is still quite preliminary. according to the technology studied at present, there are two methodologies. one is based on wrapper, which is a traditional methodology used in ie area and inherently highly web source or domain specific and always non - reusable. the other one is based on table structure recognization, which is mainly study in this thesis. the focus of this thesis is to investigate a methodology which is domain - independent and can adapt more web source to recognize table structure

Afterwards, in order to decrease the contradiction between the more complex and mass remote sensing image data and relatively slow speed of information extraction, an improved sfim image fusion method is proposed. this modified algorithm is on the base of sfim fusion technique, combines ihs method and sfim method and then replaces the former mean filter by an adaptive weighted mean filter. compared with the results of several common fusion techniques through a set of simulation tests between multispectral images and panchromatic images, it is proved that the new method can get an excellent result for the aim of improving spatial resolution while preserving the spectral information of multispectral images
