Noise Diminution Through Wavelet Based Hybrid Filter to Segment an Image

Author(s): A. Chitradevi and V. Sadasivam

Image denoising is a complicated task to remove noise from an image and also to maintain the quality, which is based on the nature of noise. In this paper, an image denoising method wavelet based asymmetrical triangular median fuzzy filter (WATMED) is proposed based on wavelet transform with fuzzy filter, wiener filter and median filter. This paper also discusses the performance analysis of various existing image denoising algorithms to remove the different types of noise. The projected filtering technique provides improved outcomes for removing all type of noises except salt and pepper noise where median filter gives good results.
