R. China PetroChina Research Institute of Petroleum Exploration and Development Beijing 100083 P R China Abstract In stratum micromodel system the underground -images always go with non -uniform background ill mination and optical axis misregistration which can affect the efficience of image segmentation and image pickup therefore background correction is needed to avoiding the bad effect of back ground asymmetry. This system imple- mented surface fitting and image filter in background correction. The principles and implement steps of the two method are introduced a comparison and analysis are made. Surface fitting can earn the exact back ground correc tion template but the operation is complex which need professional engineer who were familiar with surface equa tion the image filter can earn the background correction template by computer did not need people' s intervene Both can meet the needs of practical application Key words stratum model background correction surface fitting filter 心少少少小少少少心少少少少少心少少少少>少少少心 6497 3 Wolfgang mauerer.

When a process attempt to write access a memory address which belongs to a page whose permissions are read-only with the requested-results in an access violation exception.
