Real-time speckle and impulsive noise suppression in 3-D imaging based on robust linear combinations of order statistics

This paper presents an approach based on linear combinations of order statistics for speckle and impulsive noise reduction in the 3-D ultrasound images. The proposed technique uses the Rank M-type (RM) estimator and this one is adapted to 3-D image processing applications. The real-time implementation is presented using real clinical ultrasound images by means of use of the DSP TMS320C6711. In addition, the results from known techniques are compared with the proposed method to demonstrate its performance in terms of noise suppression, fine detail preservation, and processing time criteria.
