Paper Abstract

A new approach towards the recognition and removal of the speckle artefact in ultrasound pulse-echo images is presented. The technique utilises the behaviour of the signal's instantaneous frequency, which is the time derivative of the temporal phase. In contrast to all other approaches, the proposed method allows the speckle artefact to be recognised on a deterministic and local basis. Although presented in the context of medical ultrasound imaging, the technique is of much wider generality.
