In this paper, a novel algorithm for a car license recognition system is presented. We employ a double back-projection super-resolution image enhancement technique. Modification of initial guess estimation idea has resulted in accuracy improvement and convergence speed up. Bi-lateral back-projection filtering scheme which has been employed as an advanced preprocessor can achieve edge-preserving...

Recently, sequences generated by nonlinear dynamical systems have been considered in CDMA spread spectrum application and it has been shown that they can behave better than classical ones. In almost all cases, classical criterium have been considered to design good spreading sequences, they are based on periodic or aperiodic correlation functions, like Figure Of Merit or Maximal Correlation Pic...

In this work, we developed the concept of supercompression, i.e., compression above the compression standard used. In this context, both compression rates are multiplied. In fact, supercompression is based on super-resolution. That is to say, supercompression is a data compression technique that superpose spatial image compression on top of bit-per-pixel compression to achieve very high compres...
