%0 Journal Article %A Zapata Pérez, Juan Francisco %A Ruiz Merino, Ramón Jesús %T Reduction of the speckle noise in echocardiographic images by a cubic spline filter %D 2010 %U http://hdl.handle.net/10317/1418 %X 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. %K Electrónica %K Puntos de ruido en ultrasonido %K Filtros de adaptación %K Ranura cúbica %K Ultrasound speckle noise %K Adaptive filters %K Cubic Spline %K Medical imaging %K Imagen médica %~ GOEDOC, SUB GOETTINGEN
