ABSTRACT:
This paper presents an approach for reducing speckle
in ultrasound images using Coupled Partial Differential
Equation (CPDE) which has been obtained by uniting second-
order and the fourth-order partial differential equations. Using
PDE to reduce the speckle is the noise-smoothing methods
which is getting attention widely, because PDE can keep the
edge well when it reduces the noise. We also introduced a
median regulator to guide energy source to boost the features
in the image and regularize the diffusion. The proposed
method is tested in both simulated and real medical
ultrasound images. The proposed method is compared with
SRAD, Perona Malik diffusion and Non linear coherent
diffusion methods, our method gives better result in terms of
CNR, SSIM and FOM.
