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: |
