Effect of Symlet Filter Order on Denoising of Still Images

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 thispaper, 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 withincrease of filter order PSNR value increases but visual quality of the compressed image degradesrapidly.
