This talk concerns about mathematical mechanism for transmission error concealment. The previous methods involve concealing the transmission error for DCT (Discrete Cosine Transform) based compression line (e.g. MPEG and JEPG adopted by ISO/IEC). In this talk, we consider the mechanism to recover the transmission error of DWT(Discrete Wavelet Transform) based compression process. Also operation...

to date, a number of numerical methods, including the popular finite-difference time domain (fdtd) technique, have been proposed to simulate ground-penetrating radar (gpr) responses. despite having a number of advantages, the finite-difference method also has pitfalls such as being very time consuming in simulating the most common case of media with high dielectric permittivity, causing the for...
