Two approaches to multiple specular echo detection using split spectrum processing: moving bandwidth minimization and mathematical morphology

摘要

A split spectrum processing technique using a novel moving bandwidth minimization (MBM) method was developed to detect multiple specular targets having different spectral characteristics. Mathematical morphology (MM) algorithms were alsoimplemented in order to compare the results. An experimental approach to optimal parameter determination is described. These non-linear filtering methods are applied to medical in vivo imaging to illustrate specular detection and signal to noise ratio(SNR) enhancement.
