Analysis of Denoising with Wavelet and Wavelet Package Decomposition Methods (original) (raw)

In this presented study, it is compared that the wavelet and wavelet package decomposition for image denoising. The results shows that increasing of decomposition depth does not affect significantly PSNR rate. In the examination made on standart test images, it is concluded that although it does not show the same performance for every image, wavelet decomposition is superior to wavelet package decomposition. It is decided that it is more suitable to use denoising method based on wavelet decomposition when considering processing load as well.
