Multiscale LMMSE-based image denoising with optimal wavelet selection

global MATLAB — Mon, 16 Apr 2018 13:53:23 +0000

In this paper, we presented an LMMSE-based denoising scheme with a wavelet interscale model and discussed the optimal wavelet basis selection for it. With OWE the wavelet coefficients at the same spatial locations at two adjacent scales are represented as a vector and the LMMSE is applied to the vector. The wavelet interscale dependencies are thus exploited to improve the signal […]

Noise Filtration Technique for Medical Imaging

global MATLAB — Sat, 20 Aug 2016 06:04:31 +0000

In medical images, noise suppression is a particularly delicate and difficult task. A trade off between noise reduction and the preservation of actual image features has to be made in a way that enhances the diagnostically relevant image content. Image processing specialists usually lack the biomedical expertise to judge the diagnostic relevance of the denoising results. For example, in ultrasound images, […]
