In order to improve watermark against geometric attacks, this paper proposed a color digital imagewatermarking embedding algorithm based on SIFT feature:first,we use the SIFT feature points to constru
Viterbi decoding has been widely used in many communication systems. Due to the large computa-tion complexity, it is usually implemented with ASIC chips, FPGA, or optimized hardware. However, in soft-
Finite element methods for the elliptic variational inequality of the second kind deduced fromfriction problems or nonlinear materials in elasticity have been discussed by R.Glowinski. In this paper,
GSN (Goal Structure Notion) can be used as a means of the system safety evaluation. Within someforeign countries, it has been adopted by a growing number of companies within safety-critical industries
