Abstract :
We have previously developed a sum-table method for fast motion estimation with different motion estimators such as normalized cross-correlation (NCC), sum of square differences (SSD), sum of absolute differences (SAD). In this paper, more details of the sum table methods for different motion estimators were provided. The computational time of different motion estimators was compared in both ID and 2D cases. A fast method of strain calculation was also described. The sum-table method was further implemented in a clinical ultrasound system to image the pulse wave in the aorta in real time.
