20130238549 | Using Dimension Substitutions in OLAP Cubes - Systems, methods and computer program products that provide a framework for the creation, editing, manipulation and use of model-based, multidimensional analysis services (MAS) cubes and using substitute dimensions in such cubes are disclosed. To permit a user to obtain better and automatic access to business intelligence, a method of generating a model-based MAS cube comprises creating a data source comprising a data warehouse in the memory via the processor, creating a data source view providing a dimension, a fact and an outrigger from the created data source, and creating the MAS cube comprising at least one measure group. Using substitute dimensions comprises finding all relevant substitutions for a measure group, creating a table for the measure group in the data source view, adding a property as the primary key of the substitute dimension and generating a query containing an inner join logical link between the substitute and original dimension. | 09-12-2013 |
20100202652 | Video Fingerprinting Using Watermarks - Video fingerprinting using watermarks is described herein. A watermark encoder embeds a watermark into an input video to produce a watermarked video. The watermark encoder can choose particular regions of the video that are sufficiently complex for watermarking. Spatial and temporal complexity analyses can be performed on a per-pixel basis to locate suitable regions of the video. The watermarks can be embedded using a unique codeword associated with a given user. A watermark decoder can receive the watermarked video. In some instances, the watermarked video may have been attacked in some way after being output by the watermark encoder. In these instances, the watermark decoder can extract the watermark from the watermarked video. In turn, the watermark decoder can extract the codeword from the watermark, and compare the extracted codeword to a plurality of known codewords associated with respective users. | 08-12-2010 |
