Effect of Symlet Filter Order on Denoising of Still Images
Sarita Kumari · Advanced Computing An International Journal · 2012
In wavelet-based image coding the choice of wavelet is crucial and determines the coding performance.The current compression techniques involve time taking procedures to find out the optimal basis.In this paper, we show that Sym 5 represents the best results for compression and denoising of natural images.The performance of compression is measured in terms of CR and PSNR and it is analyzed that with increase of filter order PSNR value increases but visual quality of the compressed image degrades rapidly.
