A good watermarking scheme should be able to perform equally well on all types of images irrespective of image contents because practically watermarking has to be applied to images of all types. In this paper, it is shown that in wavelet based spread spectrum technique, watermarking at level 1 decomposition is better for textured images while watermarking at level 2 decomposition is better for ...

This paper describes the implementation and performance results for a few standard linear algebra routines on the Denelcor HEP computer. The algorithms used here are based on high-level modules that facilitate portability and perform efficiently in a xvide range of environments:The modules are chosen to be of a large enough computational granularity so that reasonably optimum performance may be...

The quality of the software's internal structure tends to decay due adaptation environmental changes. Therefore, it is beneficial maintain software benefit future phases life cycle. A common correlation exists between decaying structures and problems like smell maintenance costs. Refactoring a process artifacts based on smell. Decomposition classes one most refactoring actions Blob performed at...
