Abstract: The present invention relates to a method of image fusion, which uses the brightness difference of the current frame and the previous frame to determine whether the pixel in a frame image is static or dynamic. If the current pixel is static, the previous corresponding pixel is superimposed onto the current pixel; if the current pixel is dynamic, the previous corresponding pixel is replaced with the current pixel.

Abstract: A computer-implemented method, system and computer program product for improving accuracy and efficiency of auditing databases. A table, list or index of a database is analyzed to identify metadata, which includes time series data, user data, an Internet Protocol address and operation data. The identified metadata is associated with the corresponding record or row of the table, list or index from which the metadata was extracted. A determination is then made as to whether to record a raw data image associated with the record or row of the analyzed table, list or index based on the corresponding data operation. The identified metadata as well as the recorded data images, if any, are stored in a structured audit log. Auditing information is then obtained from a structured audit log based on matching the record or row identifier (RID) associated with the query with the RID associated with the structured audit log.
