[GDI-BitmapSRAD

Description: This paper provides the derivation of speckle reducing anisotropic diffusion [SRAD], a diffusion method tailored to ultrasonic and radar imaging applications. SRAD is the edge-sensitive diffusion for speckled images, in the same way that conventional anisotropic diffusion is the edge-sensitive diffusion for images corrupted with additive noise.

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.
