Abstract
One of the main problems to resolve in the processing of
biomedical images is the reduction of noise. The problem
is specially important if the noise has a multiplicative nature
(speckle noise), for instance if the object of analysis is
an ultrasonic image. In this report we carry out a review of
techniques which can be used to reduce this type of noise
on four-chamber view B-mode echocardiographic images
in an appropriated way. Different ways of nonlinear filtering,
adaptive techniques based on the statistical ordering
and a cubic spline interpolation will be shown as suitable
techniques for this objective but regarding quantitative and
qualitative results we have obtained, we can confirm that
a cubic spline filter is the most suitable filter that we have
reviewed.
