This paper presents a VLSI Architecture to implement the forward and inverse 2-D Discrete Wavelet Transform (FDWT/IDWT), to compress medical images for storage and retrieval. Loss...
Abstract. Users of some systems are at risk of being compelled to disclose their keys or other private data, and this risk could be mitigated if access control mechanisms supported...
There is a class of sparse matrix computations, such as direct solvers of systems of linear equations, that change the fill-in (nonzero entries) of the coefficient matrix, and invo...
This paper presents a novel VLSI architecture for high-speed data compressor designs which implement the well-known LZ77 algorithm. The architecture mainly consists of three units...
In a spatial database, an object may extend arbitrarily in space. As a result, many spatial data structures e.g., the quadtree, the cell tree, the R+-tree represent an object by p...
