Abstract :
A method is described for the determination of an immobile region of an ultrasound image of the heart. Following a noise reduction operation using an optimal signal-adaptive algorithm, a luminance-based block matching technique is used to determine the motion field. Subsequently, the motion field map as processed and the immobile region is extracted by using a 2-D texture separating algorithm
