In data fusion, we have several approximations to the desired objects, and we need to fuse them into a single – more accurate – approximation. In the traditional approach to data fusion, we usually assume that all the given approximations were obtained by minimizing the same distance function – most frequently, the Euclidean (L) distance. In practice, however, we sometimes need to use approxima...

In the past decade, the advancement in data communications was significant during explosive growth of the Internet, which led to the demand for using multimedia in portable devices. Video and Audio data streams require a huge amount of bandwidth to be transferred in an uncompressed form. The objective of this paper is to minimize the number of bits required to represent an image and also the ac...

Abstract: Thee transform coding is a major block in any compression technique. Transform coding helps in decorrelating the input data and for energy compaction which are required to implement compression. DCT is standard transform used in JPEG image compression standard and DWT is used in JPEG2000image compression standard. The DHT is a transform which provides flexibility in terms of hardware ...

We present a new method to investigate a class of diagrams which generalizes the sunset topology to any number of massive internal lines. Our attention is focused on the computation of the spectral density of these diagrams which is related to manybody phase space in D dimensional space-time. The spectral density is determined by the inverse K-transform of the product of propagators in configur...
