Direct comparison of feature tracking and autocorrelation for velocity estimation
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control
Feature tracking is an algorithm for estimating tissue motion and blood flow using pulse-echo ultrasound. It was proposed as a computationally simpler alternative to other techniques such as autocorrelation and time-domain cross correlation. The advantage of feature tracking is that it selectively extracts easily identifiable parts of the speckle signal (e.g., the local maxima), reducing the amount of information being processed. Studies on feature tracking to date have used stationary,doi:10.1109/tuffc.2007.309 fatcat:wzlftbonkncupp5dedqlrzf4yy
