Different digital media used by steganography to carry secrete information. This paper presents an algorithm to perform image steganography by combinational approach of genetic algorithm and trained auto associative neural network (TAANN). The proposed algorithm reduce needed time and needed space at encryption and at decryption level because of memory holding ability of neuron of auto associative...
Over the years ElectroCardioGram (ECG) signal has been used to assess the cardiovascular condition of humans. In practice, real time acquisition and transmission of the ECG may contain noise signals superimposed on it. In general, the signal processing algorithms employed for denoising provide optimal performance and eliminate the high frequency noise between any two beats contained in a continuous...
Paper presents a wavelet based, high performance image denoising scheme implemented in a parallel virtual machine (PVM) environment. Performance of generalized cross validation (GCV) based threshold selection scheme is poorer from CPU time viewpoint when implemented sequentially. In contrast to the traditional parallel approaches, which rely on specialized parallel machines, the present work explores...
