Description: In Medical digital images, produced by various
imaging devices like x-ray, CT, magnetic resonance imaging
(MRI), ultrasound, etc., use for diagnosis of diseases. Ultrasonic
imaging is a widely used medical imaging procedure because it is
economical, comparatively safe. The main problem during
diagnosis is the distortion. These distortions are termed as
‘Noise’. This study focus on one type noise, namely, ‘Speckle
Noise’, produced by ultrasonic devices. This paper concentrated
to reduce speckle noise and the studies the effect of different
filtering techniques for speckle reduction. The paper introduces
the speckle reducing anisotropic diffusion (SRAD) method that
reduces the noise effectively without loss of original image. The
experimental results proved that SRAD gives higher PSNR. The
performance of SRAD was superior compared to traditional lee,
frost, kaun filter. Platform: |

Description: R-EEMD facilitates
nonuniform and trial-dependent weights obtained by an
optimization procedure during ensemble combination and results
in less decomposition errors when compared with the conventional
ensemble empirical mode decomposition techniques. A theoretic
result is then extended to demonstrate that R-EEMD has an ability
to solve the mode mixing problem frequently encountered in EMD
and improve the decomposition performance with adequate noise
strength when separating a composite two-tone signal. Based on
the proposed R-EEMD framework, a novel clutter rejection filter
for ultrasound color flow imaging is designed Platform: |
