    • Enhanced VLSI Manufacturability Using an Integrated CAD Framework 

      Fossati, Humberto M.; Tittel, Frank K.; Wilson, William L.; Cavallaro, Joseph R. (1994-01-01)
      Continued improvements in VLSI performance, circuit density and production costs are possible, in part, do to significant advances in lithography. As feature sizes get smaller, design houses are faced with either improving ...
    • Enhancement of Decompressed Images at Low Bit Rates 

      Gopinath, Ramesh A.; Lang, Markus; Guo, Haitao; Odegard, Jan E. (1994-07-20)
      Transform coding at low bit rates introduces artifacts associated with the basis functions of the transform. For example, decompressed images based on the DCT (discrete cosine transform)- like JPEG<sup>16</sup> - exhibit ...
