BEMD Based Ultrasound Image Speckle Reduction Technique Using Pixel-Wise Wiener Filtering

In this paper, an improved Bidimensional Empirical Mode Decomposition (BEMD) based speckle reduction technique for ultrasound images has been proposed. The noisy image decomposed into its Intrinsic Functions (IMFs) and a~residue. noise component of the low order IMFs is removed with pixel-wise Wiener filtering. reconstructed these filtered IMFs, high residue. performance proposed method tested on synthetic as well real having components different variance. experimental results show that algorithm performs better than other existing methods in terms various quality matrices.
