E Divya, P.rajkumar . Steganographic Data Hiding using DWT and Particle Swarm Optimization. International Journal of Computer Applications. 117, 14 ( May 2015), 30-34. DOI=10.5120/20624-3357
Abstract
This paper discusses the steganographic data hiding using the wavelet approach and the optimisation technique. The Discrete Wavelet Transform Using Haar Wavelet gives the excellent peak signal to noise ratio (PSNR) and less computation time. The particle swarm optimisation algorithm (PSO) is also used to hide the data so that the PSNR is improved. The results reveal the DWT using Haar wavelet and PSO algorithm gives excellent PSNR.
