Abstract :
An image processing technology for featal organ tracking in ultrasound image sequences is presented. The technology includes a variety of algorithms for image calibration, noise suppression, target locations, signal interpolation and image geometrical transformation and is based on an extensive use of nonlinear signal processing in the domain of orthogonal transforms such as DFT and DCT.
